Background

With the continuous development of terminal technology, more and more terminal devices with operating systems are provided. Generally, a terminal device manufacturer and an Application (APP) manufacturer can develop a plurality of functional modules that can be commonly used by applications (including system applications and third-party applications) based on an operating system of a terminal device, and these common functional modules are referred to as common feature functions.

At present, an application manufacturer will package a common feature function into an application, so that if the application is started, an operating system of a terminal device will load the common feature function in the application into a memory when the application is loaded, so that the application can implement the function provided by the common feature function.

However, when a plurality of applications in the terminal device use the same common feature function, the common feature function may be repeatedly loaded by the operating system of the terminal device for a plurality of times, so that the memory occupancy rate of the terminal device is relatively high, thereby affecting the performance of the operating system of the terminal device.

Disclosure of Invention

In the application, because the first application loaded by the system class loader is an application at an operating system level, other applications in the operating system can share the first application loaded in the memory, so that the other applications sharing the first application can directly call the first application in the memory after being started, and the first application does not need to be loaded again when the other applications sharing the first application are started, so that the first application can be prevented from being repeatedly loaded for many times when the other applications sharing the first application are started, the memory occupancy rate of the terminal device can be reduced, and the operating system performance of the terminal device can be improved.

In a first optional implementation manner of the first aspect, the method for determining, by the terminal device, that the first application is an application that implements a common feature function includes: and the terminal equipment determines the first application as the application realizing the public characteristic function according to the identifier of the first application included in the predefined public characteristic function list. In this way, the terminal device may determine, through the predefined common characteristic function list, that the first application is an application implementing a common characteristic function.

In a second optional implementation manner of the first aspect, the method for determining, by the terminal device, that the first application is an application that implements a common feature function includes: the terminal equipment inquires whether the identifier of the first application is included in a predefined public characteristic function list or not; and under the condition that the public characteristic function list comprises the identifier of the first application, the terminal equipment determines the first application as the application realizing the public characteristic function. In this way, the terminal device may determine whether the first application is an application implementing a common feature function through a predefined common feature function list.

In a third optional implementation manner of the first aspect, the method for determining, by the terminal device, that the first application is an application that implements a common feature function includes: the terminal equipment reads a first attribute of a first application (the first attribute is used for indicating whether the first application is an application realizing a common characteristic function); and in the case that the first attribute indicates that the first application is an application that implements a common characteristic function, the terminal device determines that the first application is an application that implements a common characteristic function. In this way, the terminal device can determine whether the application is an application that implements a common characteristic function by identifying the attribute of the application.

The symbol "/" herein denotes a relationship in which the associated object is or, for example, a/B denotes a or B.

The terms "first," "second," and "third," etc. in the description and claims of this application are used for distinguishing between different objects and not for describing a particular order of the objects. For example, the first application, the second application, the third application, and so on are for distinguishing different applications, and are not for describing a specific order of applications.

In the embodiments of the present application, words such as "exemplary" or "for example" are used to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary" or "e.g.," is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.

In the description of the embodiments of the present application, the meaning of "a plurality" means two or more unless otherwise specified. For example, a plurality of applications refers to two or more applications; multiple classes refer to two or more classes.

Some terms or expressions referred to in the embodiments of the present application are explained first below.

Common feature function: the method refers to a functional module which can be commonly used by a terminal equipment manufacturer and an application manufacturer based on a plurality of applications (including system applications and third-party applications) developed by an operating system of the terminal equipment.

The system application comprises the following steps: refers to an application carried by an operating system of the terminal equipment. System applications typically cannot be uninstalled or deleted.

A third party application: refers to an application developed by an application vendor, some organization, or an individual. Third party applications can typically be installed, uninstalled or deleted.

Class loader: the method refers to a tool for loading the application class into the Java virtual machine before the Java virtual machine runs the application class. The Class Loader comprises a root Class Loader (Boot Class Loader), a System Class Loader (System Class Loader) and a Path Class Loader (Path Class Loader). And under the default condition, the parent class loader of the path class loader and the parent class loader of the system class loader are root class loaders. In the software development process, a developer may modify the parent class loader of the path class loader according to actual usage requirements, for example, in this embodiment, the parent class loader of the path class loader may be set as a system class loader.

A system upgrade patch package: refers to a compressed package in which an application installation package set developed based on a specific version is packaged.

Upgrading a patch package: refers to a compressed package generated from members (each class including a plurality of members) in a certain class/classes after update (including repair and addition) in an application. The space occupied by the upgrade patch package is smaller than the space occupied by the system upgrade patch package, or the resources occupied by the upgrade patch package are less than the resources occupied by the system upgrade patch package.

At present, since application manufacturers usually package a common feature function into applications, if a plurality of applications in a terminal device use the same common feature function, the common feature function may be repeatedly loaded by an operating system of the terminal device for many times in the process of starting the applications, so that the memory occupancy rate of the terminal device is high, and the performance of the operating system of the terminal device is affected.

In addition, at present, when an application is upgraded, because an application installation package for repairing a problem and an application installation package with newly added functions are assembled and packaged into a system upgrade patch package for upgrading an operating system of a terminal device, that is, the system upgrade patch package may include a plurality of application installation packages, and each application installation package is upgraded and applied at a class granularity, resources occupied by the system upgrade patch package are large, the release period of the system upgrade patch package is long, and the operating system of the terminal device needs to be restarted for upgrading, so that the application cannot be quickly repaired.

In order to solve the foregoing problem, in an aspect, an embodiment of the present application provides a method for loading an application, where after a terminal device is started, if the terminal device determines that a certain application (for example, a first application in this embodiment) is an application that implements a common feature function (the determination process may be executed before the terminal device scans the application after the terminal device is started, or may be executed after the terminal device scans the application after the terminal device is started), the terminal device may load the application into a memory of the terminal device by using a system class loader. Because the application loaded by the system class loader is the application at the operating system level, other applications in the operating system can share the application loaded in the memory, so that the application in the memory can be directly called after the other applications sharing the application are started, and the application does not need to be loaded again when the other applications sharing the application are started, so that the application can be prevented from being repeatedly loaded for many times when the other applications sharing the application are started, the memory occupancy rate of the terminal equipment can be reduced, and the operating system performance of the terminal equipment is improved.

On the other hand, the embodiment of the present application provides an application upgrading method, where, when a terminal device determines that an application is upgradable, the terminal device sends an upgrade patch request message to a server to request an upgrade patch package from the server, and after the terminal device receives the upgrade patch package sent by the server, the terminal device uses the upgrade patch package to directly upgrade the application at a member granularity. On one hand, the upgrade patch package requested by the terminal device to the server is used for upgrading the application at the member granularity, so that compared with the prior art that the application is upgraded at the class granularity (one class includes a plurality of members), the upgrade patch package in the embodiment of the application is smaller, so that the resources occupied by the upgrade patch package can be reduced, and the release period of the upgrade patch package can be shortened, thereby enabling the application to be quickly repaired. On the other hand, because the application is directly upgraded in the embodiment of the application, compared with the prior art that the application is upgraded by upgrading the operating system of the terminal device, the operating system of the terminal device does not need to be restarted after the application is upgraded in the embodiment of the application, so that the application can be repaired more quickly.

The method for loading the application and the method for upgrading the application provided by the embodiment of the present application may be applied to a terminal device, and may also be applied to a functional module or a functional entity capable of implementing loading the application and upgrading the application in the terminal device, which is not specifically limited in the embodiment of the present application.

First, an exemplary description is given of a hardware structure of a terminal device provided in an embodiment of the present application.

Specifically, taking the example that the terminal device provided in the embodiment of the present application is a mobile phone, each component of the mobile phone is specifically described with reference to fig. 1.

For example, as shown in fig. 1, a mobile phone provided in an embodiment of the present application may include: a processor 10, a Radio Frequency (RF) circuit 11, a power supply 12, a memory 13, an input module 14, a display module 15, and an audio circuit 16. Those skilled in the art will appreciate that the configuration of the handset shown in fig. 1 does not constitute a limitation of the handset, and may include more or fewer components than those shown in fig. 1, or may combine some of the components shown in fig. 1, or may be arranged differently than those shown in fig. 1.

The processor 10 is the control center of the handset and connects the various parts of the entire handset using various interfaces and lines. The overall monitoring of the mobile phone is performed by executing or executing software programs and/or modules stored in the memory 13 and calling data stored in the memory 13 to perform various functions of the mobile phone and process the data. Optionally, the processor 10 may include one or more processing modules, for example, the processor 10 may integrate an application processor and a modem processor, wherein the application processor mainly processes an operating system, a user interface, an application program, and the like; the modem processor mainly handles wireless communication and the like. It will be appreciated that the modem processor described above may also be a processor separate from the processor 10.

The RF circuit 11 may be used to receive and transmit signals during the transmission and reception of information or during a call. For example, the downlink information of the base station is received and then processed by the processor 10; in addition, the uplink data is transmitted to the base station. Typically, the RF circuit includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a Low Noise Amplifier (LNA), and a duplexer. In addition, the handset can also communicate wirelessly with other devices in the network via the RF circuit 11. The wireless communication may use any communication standard or protocol, including but not limited to global system for mobile communications (GSM), General Packet Radio Service (GPRS), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), Long Term Evolution (LTE), email, and Short Messaging Service (SMS), among others.

The power supply 12 may be used to power various components of the handset, and the power supply 12 may be a battery. Optionally, the power supply may be logically connected to the processor 10 through a power management system, so as to implement functions of managing charging, discharging, power consumption management, and the like through the power management system.

The memory 13 may be used to store software programs and/or modules, and the processor 10 executes various functional applications and data processing of the mobile phone by operating the software programs and/or modules stored in the memory 13. The memory 13 may mainly include a storage program area and a storage data area, wherein the storage program area may store an operating system, an application program required by at least one function (such as a sound playing function, an image playing function, etc.), and the like; the storage data area may store data (such as audio data, image data, a phonebook, etc.) created according to the use of the cellular phone, and the like. Further, the memory 13 may include high speed random access memory, and may also include non-volatile memory, such as at least one magnetic disk storage device, flash memory device, or other volatile solid state storage device.

The input module 14 may be used to receive input numeric or character information and generate key signal inputs related to user settings and function controls of the handset. In particular, the input module 14 may include a touch screen 141 as well as other input devices 142. The touch screen 141, also referred to as a touch panel, may collect touch operations of a user (e.g., operations of the user on or near the touch screen 141 using any suitable object or accessory such as a finger, a stylus, etc.) thereon or nearby, and drive the corresponding connection device according to a preset program. Alternatively, the touch screen 141 may include two parts of a touch detection device and a touch controller. The touch detection device detects the touch direction of a user, detects a signal brought by touch operation and transmits the signal to the touch controller; the touch controller receives touch information from the touch sensing device, converts the touch information into touch point coordinates, sends the touch point coordinates to the processor 10, and can receive and execute commands sent by the processor 10. In addition, the touch screen 141 may be implemented in various types, such as a resistive type, a capacitive type, an infrared ray, and a surface acoustic wave. Other input devices 142 may include, but are not limited to, one or more of a physical keyboard, function keys (such as volume control keys, power switch keys, etc.), a trackball, a mouse, and a joystick.

The display module 15 may be used to display information input by or provided to the user and various menus of the cellular phone. The display module 15 may include a display panel 151. Alternatively, the display panel 151 may be configured in the form of a Liquid Crystal Display (LCD), an organic light-emitting diode (OLED), or the like. Further, the touch screen 141 may cover the display panel 151, and when the touch screen 141 detects a touch operation thereon or nearby, it is transmitted to the processor 10 to determine the type of the touch event, and then the processor 10 provides a corresponding visual output on the display panel 151 according to the type of the touch event. Although the touch screen 141 and the display panel 151 are shown as two separate components in fig. 1 to implement the input and output functions of the mobile phone, in some embodiments, the touch screen 141 and the display panel 151 may be integrated to implement the input and output functions of the mobile phone.

Audio circuitry 16, a speaker 161 and a microphone 162 to provide an audio interface between the user and the handset. In one aspect, the audio circuit 16 may transmit the converted electrical signal of the received audio data to the speaker 161, and convert the electrical signal into an audio signal for output by the speaker 161. On the other hand, the microphone 162 converts the collected sound signal into an electrical signal, converts the electrical signal into audio data after being received by the audio circuit 16, and outputs the audio data to the RF circuit 11 through the processor 10 to be transmitted to, for example, another cellular phone, or outputs the audio data to the memory 13 through the processor 10 for further processing.

Optionally, the handset as shown in fig. 1 may also include various sensors. Such as gyroscope sensors, hygrometer sensors, infrared sensors, magnetometer sensors, etc., and will not be described in detail herein.

Specifically, in executing S102, if the terminal device determines that the currently scanned application is the first application, that is, the terminal device currently scans the first application, the terminal device may continue to execute S104 described below.

(2) The terminal equipment inquires whether the identifier of the first application is included in a predefined public characteristic function list or not; under the condition that the public characteristic function list comprises the identifier of the first application, the terminal equipment determines the first application as the application realizing the public characteristic function; in a case where the identification of the first application is not included in the common characteristic function list, the terminal device determines that the first application is not an application that implements the common characteristic function.

It is understood that in (2), the embodiment of the present application may perform S102 first, and then perform S103. Specifically, in executing S102, if the terminal device determines that the identifier of the currently scanned first application is in the predefined common characteristic function list, the terminal device may determine that the first application is an application implementing a common characteristic function, at which point the terminal device may continue to execute S104 described below.

In an embodiment of the application, a list of common feature functions may be predefined, and an identification of an application implementing each common feature function, for example, an identification of the first application, may be added to the list of common feature functions. The common feature function list may be preset to a directory of an operating system of the terminal device. Thus, in the above (1), the terminal device may determine that the first application is an application that implements the common characteristic function by reading the identifier of each application (including the first application) included in the common characteristic function list; in the above (2), the terminal device may determine whether the first application is an application implementing the common feature function by inquiring whether an identifier of a currently scanned application (e.g., the first application) is included in the common feature function list.

It is understood that the above list of common feature functions is only exemplary, and in actual implementation, the common feature functions can be implemented by a configuration file or the like. Specifically, the determination may be determined according to actual use requirements, and the embodiments of the present application are not limited.

The common feature functions provided in the embodiments of the present application are described below with reference to table 1, taking several common feature functions listed above as examples.

TABLE 1

Identification of applications	Common feature function
APP1	Beautifying function
APP2	Animation special effect function
APP3	Positioning function
APP4	Search function
APP5	Face recognition function
APP6	Fingerprint identification function
APP7	Timing function
APP8	Translation function
APP9	Play function
APP10	Voice function

In the list of common characteristic functions shown in table 1, table 1 may only include the identification of the application when it is actually implemented, i.e. the column of common characteristic function in table 1 is the explanation of the common characteristic function implemented by the system application. In actual implementation, it can be predefined which common feature function each application is specifically used for. In this way, the terminal device may determine that an application is an application implementing a common feature function by reading an identifier of the application in the predefined common feature function list; or when the terminal device scans an application, if the terminal device finds the identifier of the application in the predefined public characteristic function list, the terminal device may determine that the application is an application implementing a public characteristic function.

For example, in combination with table 1, in an example where S103 is executed after S102, assuming that the common characteristic function is a positioning function implemented by APP3, when the terminal scans APP3, if the terminal finds an identifier of APP3 (for example, APP3) in table 1, the terminal may determine that APP3 is an application implementing the common characteristic function. Specifically, in the process of scanning the APP3, the terminal device may determine that the APP3 is specifically an application that implements the positioning function by analyzing each resource and each attribute of the APP 3.

It is understood that, in the embodiment of the present application, for other common characteristic functions in table 1 above, the determination method may be similar to the determination method of APP3 listed above, and is not listed here.

Optionally, in this embodiment of the application, the identifier of the first application may uniquely identify the first application. The identifier of the first application may be a name of the first application, an address where the first application is installed, or a combination of one or more of numbers, chinese characters, letters, characters, character strings, serial numbers, and the like, which can uniquely identify the first application. Specifically, the setting may be according to actual use requirements, and the embodiment of the present application is not limited.

(3) The terminal equipment reads a first attribute of a first application, wherein the first attribute is used for indicating whether the first application is an application realizing a public characteristic function or not; under the condition that the first attribute indicates that the first application is an application realizing a common characteristic function, the terminal device determines that the first application is the application realizing the common characteristic function; in a case where the first attribute indicates that the first application is not an application implementing a common characteristic function, the terminal device determines that the first application is not an application implementing a common characteristic function.

It can be understood that, since the attribute of the first application is analyzed in the process of scanning the first application, in (3), in the embodiment of the present application, S102 may be executed first, and then S103 may be executed.

In the embodiment of the application, each application has a plurality of attributes, wherein a first attribute in the plurality of attributes can be used for indicating whether the application is an application realizing a common characteristic function. In this way, the terminal device can determine whether the read application is an application that implements a common characteristic function by reading the first attribute of each application.

Optionally, taking the first application in the embodiment of the present application as an example, the first attribute may be a repository (library) attribute of the first application, and since the repository attribute may be commonly shared by each application, the embodiment of the present application may indicate whether the first application is an application that implements a common feature function by setting the repository attribute of the first application.

Specifically, the repository attribute includes a name (name) field, and in the embodiment of the application, the name field in the repository attribute is set as the name of the application, so that the application can be shared by other applications, that is, the function implemented by the application is a common characteristic function. That is, still taking the first application in the embodiment of the present application as an example, the name field in the repository attribute of the first application may be set as the name of the first application, so that the first application may be shared by other applications, that is, the function implemented by the first application is a common feature function.

For example, taking the beauty function in the public characteristic functions listed above as an example, in the embodiment of the present application, the name field in the repository attribute of the application implementing the beauty function may be set as the name of the application, so that the application may be shared by other applications, that is, the beauty function implemented by the application is one public characteristic function.

In the embodiment of the present application, the name of the application may be other identifiers listed above, which can uniquely identify the application. For the description of the identifier of the application, reference may be specifically made to the description related to the identifier of the application in (1) above, and details are not repeated here.

In the embodiment of the present application, if the terminal device determines that the first application is an application that implements the common feature function, the terminal device may continue to execute S104 and S105 described below.

In this embodiment of the application, since the terminal device usually defaults to loading the application by using the path class loader after scanning a certain application, if the terminal device determines that the first application is not an application that implements a common feature function, that is, the first application is a common application and does not need to be loaded globally, the terminal device may default to loading the first application to a memory of the terminal device by using the path class loader.

It should be noted that, in this embodiment of the application, each application includes multiple classes, taking the first application as an example, the first application also includes multiple classes, and the loading, by the terminal device, of the first application to the memory of the terminal device by using the path class loader means that the terminal device loads the class names of the multiple classes of the first application to the memory of the terminal device (this process is also referred to as preloading), and when the first application is specifically used, the terminal device loads the contents of the multiple classes to the memory.

And S104, the terminal equipment loads the first application to a memory of the terminal equipment by adopting a system loader.

In the embodiment of the present application, because the content loaded by the system class loader is usually at an operating system level, that is, the content loaded by the system class loader may be shared by all applications under the operating system, the embodiment of the present application may use the system class loader to load the common feature function, so that the loaded common feature function may be shared by all applications in the terminal device, thereby achieving the purpose that the common feature function is loaded globally.

It can be understood that, in S104, the terminal device also loads the class names of the multiple classes of the first application into the memory of the terminal device (this process is also referred to as preloading), and the terminal device loads the content of the multiple classes into the memory only when the first application is specifically used.

It is to be understood that, in this embodiment of the present application, the above-mentioned S102-S104 are described by taking as an example that the terminal device scans and determines one application (i.e. the above-mentioned first application) implementing one common feature function, and for other applications implementing other common feature functions in the terminal device, the methods for scanning and determining the terminal device are all similar to the method for scanning and determining the above-mentioned first application by the terminal device, and this embodiment of the present application is not particularly limited.

And S105, the terminal equipment scans other applications in sequence.

Wherein, each application in S105 may include a system application and a third party application.

It is understood that, if the first application in S101-S104 is a system application, the embodiment of the present application may execute S101-S104 first, and then execute S105; and when S105 is executed, the system applications other than the first application may be scanned, and then all the third party applications may be scanned. If the first application in S101-S104 is a third-party application, the embodiment of the present application may first perform S105 to scan all system applications, then perform S101-S104, and then perform S105 to scan other third-party applications except the first application. Wherein, fig. 2 is illustrated by the way that S105 is executed after S101-S104.

In the method for loading an application provided in this embodiment of the present application, after the terminal device is started, if the terminal device determines that a certain application (for example, a first application in this embodiment) is an application that implements a common characteristic function (the determination process may be executed before scanning the application after the terminal device is started, or may be executed after scanning the application after the terminal device is started), the terminal device may load the first application into a memory of the terminal device by using a system class loader. Because the first application loaded by the system class loader is an application at an operating system level, other applications in the operating system can share the first application loaded in the memory, so that the other applications sharing the first application can directly call the first application in the memory after being started, and the first application does not need to be loaded again when the other applications sharing the first application are started, so that the first application can be prevented from being repeatedly loaded for many times when the other applications sharing the first application are started, the memory occupancy rate of the terminal device can be reduced, and the operating system performance of the terminal device can be improved.

Optionally, with reference to fig. 2, as shown in fig. 3, after S105 described above, the method for loading an application provided in the embodiment of the present application may further include S106 to S111 described below.

And S106, the terminal equipment starts the second application.

The second application may be an application that calls the first application in the terminal device (that is, the second application is an application that uses the common feature function implemented by the first application in the terminal device), or may be an application that does not call the first application in the terminal device (that is, the second application is an application that does not use the common feature function implemented by the first application in the terminal device).

S107, the terminal device creates a path class loader of the second application.

Since the terminal device loads the application by default using the path class loader, the terminal device first creates the path class loader of the second application when the terminal device starts the second application.

S108, the terminal device determines whether the second application is the application of the terminal device for calling the first application.

In this embodiment of the application, if the terminal device determines that the second application is an application that does not invoke the first application in the terminal device, the terminal device may continue to execute S109 described below; if the terminal device determines that the second application is an application of the terminal device that invokes the first application, the terminal device may continue to perform S110 and S111 described below.

And S109, the terminal equipment loads the second application to the memory of the terminal equipment by adopting the path class loader.

The following embodiment exemplarily illustrates the first application and the second application by taking the second application as an application for calling the first application in the terminal device as an example.

It can be understood that, in this embodiment of the application, if the second application is an application in the terminal device that invokes the first application, an identifier of the first application (for example, a name of the first application) may be preset in the second application, so that the terminal device may invoke the first application through the identifier preset in the second application, thereby providing the common feature function implemented by the first application for the user. Moreover, the identifier of the first application is preset in the second application, and is not the implementation code of the first application, so that the terminal device does not need to load the first application when loading the second application.

For example, in the case of the common characteristic function listed in S103, assuming that the common characteristic function implemented by the first application is a beauty function, the second application may be any application using the beauty function, for example, the second application may be a camera-type application, a health-type application, or a sports-type application.

Further, assuming that the common feature function implemented by the first application is an animation special effect function, the second application may be any application using the animation special effect function, for example, the second application may be a camera-type application, a map-type application, a weather-type application, a shopping-type application, a sports-type application, a media-type application, a browser-type application, or a health-type application.

Further assuming that the common feature function implemented by the first application is a positioning function, the second application may be any application using the positioning function, for example, the second application may be a map-type application, a weather-type application, a shopping-type application, or a sports-type application.

Further assuming that the common feature function implemented by the first application is a search function, the second application may be any application using the search function, for example, the second application may be a media-type application, a reading-type application, or a browser-type application.

Further, assuming that the common feature function implemented by the first application is a face recognition function, the second application may be any application using the face recognition function, for example, the second application may be a camera-type application, a payment-type application, a health-type application, a sports-type application, or a bank-type application.

Further, assuming that the public characteristic function implemented by the first application is a fingerprint identification function, the second application may be any application using the fingerprint identification function, for example, the second application may be a screen lock application, a payment application, or a security and privacy tool application.

Further, assuming that the common feature function implemented by the first application is a timing function, the second application may be any application using the timing function, for example, the second application may be a clock-type application, a trip-type application, a health-type application, a sports-type application, or a mailbox-type application.

Further assuming that the common property function implemented by the first application is a translation function, the second application may be any application using the translation function, for example, the second application may be a reading-type application or a learning-type application.

Further, assuming that the common feature function implemented by the first application is a play function, the second application may be any application using the play function, for example, the second application may be a shopping application, a media application, or a browser application.

Further assuming that the common feature function implemented by the first application is a voice function, the second application may be any application using the voice function, for example, the second application may be a map-based application, a media-based application, a browser-based application, or a social-based application.

It is to be understood that, in the embodiment of the present application, some of the second applications listed in the above examples may be system applications or third party applications. For example, the camera class application may be a system camera class application or a third-party camera class application; the map application can be a system map application or a third-party map application; the weather application may be a system weather application or a third-party weather application, and the like, which may be determined specifically according to an actual situation, and the embodiment of the present application is not limited.

S110, the terminal device sets a parent class loader of a path class loader of the second application as a system class loader.

In the embodiment of the application, according to a parent delegation mechanism of class loading, when a terminal device loads a class, a system class loader is firstly adopted to search for the class to be loaded, and if the system class loader does not search for the class to be loaded, the applied path class loader searches and loads the class. According to this principle, since the terminal device is loaded by using the system class loader when preloading the first application in S104, in order to enable the second application to be started, the terminal device may search the first application based on the second application, that is, enable the second application to normally provide the common characteristic function implemented by the first application for the user by invoking the first application, in this embodiment of the application, after the terminal device creates the path class loader of the second application, the terminal device may set the parent class loader of the path class loader as the system class loader, so that the terminal device may directly load the second application to the memory of the terminal device by using the system class loader according to the biparental delegation mechanism of class loading. As described in S111 below, the terminal device uses the system class loader to load the second application into the memory of the terminal device.

And S111, the terminal equipment loads the second application to a memory of the terminal equipment by adopting a system loader.

In the embodiment of the application, the terminal device loads the second application to the memory of the terminal device by using the system class loader, so that after the second application is started, the terminal device can find the first application based on the second application (the first application is also loaded to the memory of the terminal device by using the system class loader), that is, the second application can normally provide the common characteristic function realized by the first application for the user by calling the first application.

For example, still taking the first application to implement the above-mentioned beauty function, taking the second application as a camera application as an example, after the terminal device loads the first application implementing the beauty function and the camera application calling the first application by using the system loader, the terminal device may search the first application implementing the beauty function based on the camera application, thereby ensuring that the camera application can normally provide the user with the beauty function implemented by the first application by calling the first application.

The various class loaders in the embodiments of the present application are described below with reference to FIG. 4 as an example. Fig. 4 is a schematic diagram illustrating relationships among various class loaders in the terminal device according to the embodiment of the present application. In fig. 4, the parent class loader (shown as parent in fig. 4) of the path class loader is a system class loader or a root class loader (by default, the parent class loader of the path class loader is the root class loader), and the parent class loader of the system class loader is the root class loader. The path class loader is used for loading common applications (such as music. apk and bluetooth. apk in fig. 4, music. apk represents a music installation package in an android operating system, and bluetooth. apk represents a bluetooth installation package in the android operating system), system services (such as services. jar in fig. 4, services. jar represents one service in the android operating system), and the like. The system class loader is used to load an application that implements a common property function, such as the first application in the embodiments of the present application (e.g., feature.apk in fig. 4, which represents a common property function in an android operating system). The root class loader is used for loading a system framework of the android operating system, such as a core library layer (e.g., like libcore. jar in fig. 4) and a framework layer (e.g., like framework. jar in fig. 4) in the android operating system.

Optionally, with reference to fig. 2, after S105 described above, the method for loading an application provided in the embodiment of the present application may further include S112 to S117 described below.

And S112, the terminal equipment sends an upgrade patch request message to the server.

S113, the server receives the upgrade patch request message sent by the terminal equipment.

In this embodiment, a possible implementation manner is that, when the terminal device determines that an application running in the terminal device, for example, a third application in this embodiment, is abnormal, the terminal device determines to upgrade the third application, and at this time, the terminal device may trigger execution of S112 to S117.

Another possible implementation manner is that the terminal device may periodically check whether there is an application, for example, an upgrade patch package of a third application in this embodiment, on the server for a predefined first time period, and when the terminal device determines that there is an upgrade patch package of the third application on the server, the terminal device determines to upgrade the third application, and at this time, the terminal device may trigger execution of S112-S117.

Optionally, in another possible implementation manner described above, the predefined first time may be any predefined time, such as a day, a week, or a month, and the like, and may be specifically defined according to an actual use requirement, which is not limited in the embodiment of the present application.

Wherein, the upgrade patch request message is used for requesting an upgrade patch package from the server. The upgrade patch package is used for directly upgrading a third application at the member granularity, wherein the third application is a system application in the terminal equipment.

Since the third-party application may be generally downloaded from an application store (APP store), the third application in the embodiment of the present application mainly refers to a system application.

In an embodiment of the present application, each application includes a plurality of classes, and each class includes a plurality of members. The upgrade patch package may include at least one member, wherein when the number of members is multiple, the multiple members may be members in different classes. In the embodiment of the application, when the third application is upgraded by using the upgrade patch package, the third application can be upgraded at the member granularity, that is, only the members needing to be upgraded need to be upgraded, and the whole class where the members are located does not need to be upgraded. For example, a member of the third application that requires repair may be replaced with a member of the upgrade patch package, and/or a member of the upgrade patch package may be newly added to the third application. Compared with the class-granularity upgrade application in the prior art, the upgrade patch package in the embodiment of the application is smaller, so that the resources occupied by the upgrade patch package can be reduced, the release period of the upgrade patch package can be shortened, and the third application can be quickly repaired.

In addition, since the third application is directly upgraded in the embodiment of the present application, compared with the prior art that the application is upgraded by upgrading the operating system of the terminal device, the operating system of the terminal device does not need to be restarted after the third application is upgraded in the embodiment of the present application, so that the third application can be repaired more quickly.

Optionally, in this embodiment of the application, the upgrade patch request message may include current version information of the third application. The current version information of the third application can uniquely identify the current version of the third application. The current version information of the third application may be a combination of one or more of numbers, chinese characters, letters, character strings, serial numbers, and the like. Specifically, the determination may be determined according to actual use requirements, and the embodiments of the present application are not limited.

Optionally, in this embodiment of the application, the upgrade patch package may include at least one resource and at least one identifier. Wherein each identifier is used to uniquely identify a resource. The at least one resource includes at least one of a first resource and a second resource, the first resource is used for repairing an original resource of the third application (the first resource may also be referred to as a repair resource of the third application), and the second resource is an added resource of the third application (that is, the second resource is a resource added on the basis of the original resource of the third application).

It should be noted that, in the embodiment of the present application, the identifier for identifying a resource in the upgrade patch package may be considered as a member, that is, the upgrade patch package includes at least one member.

Optionally, in this embodiment of the present application, the resource may be a combination of one or more of numbers, characters (including characters and letters, etc.), pictures, and files (including files in various formats). Specifically, the determination may be determined according to actual use requirements, and the embodiments of the present application are not limited.

The identifier for uniquely identifying the resource may be a name of the resource, a storage address of the resource, or a combination of one or more of other numbers, chinese characters, letters, characters, character strings, serial numbers, and the like, which can uniquely identify the resource. Specifically, the determination may be determined according to actual use requirements, and the embodiments of the present application are not limited.

Illustratively, taking still the third application as an example, as shown in fig. 5, a schematic diagram for generating idmap provided in the embodiment of the present application is shown (due to the specificity of the resource, fig. 5 only shows an identifier for uniquely identifying the resource, and does not show the resource). In fig. 5, part a represents code for identifying an original resource in the third application; part B represents a code in the upgrade patch package for identifying the repair resource of the third application and the identifier of the newly added resource of the third application, specifically, part B1 represents a code of the identifier of the repair resource of the third application, and part B2 represents a code of the identifier of the newly added resource of the third application. With the method for upgrading an application provided by the embodiment of the present application, when the third application is upgraded at a member granularity by using an upgrade patch package, by generating and expanding idmap and executing code in the idmap, it may be implemented to replace an original resource of the third application with a repair resource of the third application and add a new resource of the third application to the back of other resources in the third application, for example, as shown in part C in fig. 5, in the idmap, as a schematic diagram of the generated and expanded idmap, it may be implemented to replace a1 with B1 in part a by executing C1 and C3, and it may be implemented to add B2 in part a by executing C2 and C3. On one hand, since the upgrade patch package requested by the terminal device from the server is used for upgrading the third application at the granularity of members (e.g., B1 and B2 shown in fig. 5), the upgrade patch package in the embodiment of the present application is smaller than that in the prior art, in which the application is upgraded at the class granularity (one class includes a plurality of members), so that the resources occupied by the upgrade patch package can be reduced, and the release cycle of the upgrade patch package can be shortened, thereby enabling the third application to be repaired quickly. On the other hand, since the third application is directly upgraded in the embodiment of the present application, compared with the application upgraded by upgrading the operating system of the terminal device in the prior art, the operating system of the terminal device does not need to be restarted after the third application is upgraded in the embodiment of the present application, so that the third application can be repaired more quickly.

It is to be understood that in FIG. 5 above, if A is considered to be a class, then A1, B1, and B2 may be considered to be three members.

S114, the server searches for the upgrade patch package corresponding to the current version information according to the current version information of the third application in the upgrade patch request message.

In the embodiment of the application, the server can store the mapping relationship between the version information of a plurality of applications and a plurality of upgrade patch packages. The mapping relationship between the version information of the plurality of applications and the plurality of upgrade patch packs may include a mapping relationship between the current version information of the third application and the upgrade patch packs. In this way, after the server receives the upgrade patch request message sent by the terminal device, the server may search, according to the current version information of the third application in the upgrade patch request message, the upgrade patch package corresponding to the current version information on the server.

For example, taking the example that the current version information of the third application is a combination of numbers and letters listed in the above S113, the mapping relationship between the current version information of the third application and the upgrade patch package will be described with reference to table 2.

TABLE 2

Current version information of third application	Upgrade patch package
V1	Upgrade patch Package 1
V2	Upgrade patch Package 2
V3	Upgrade patch package 3
V4	Upgrade patch package 4

As shown in table 2, assuming that the current version information of the third application carried in the upgrade patch request message received by the server is V2, the server may search for the upgrade patch package corresponding to V2 in table 2, for example, the server searches for the upgrade patch package 2 corresponding to V2 in table 2, and then the server sends the upgrade patch package 2 to the terminal device, so that the terminal device upgrades the third application using the upgrade patch package 2. Therefore, the phenomenon of error caused by the fact that the versions are not corresponding when the third application is upgraded can be avoided.

And S115, under the condition that the server finds the upgrade patch package corresponding to the current version information, the server sends the upgrade patch package to the terminal equipment.

It can be understood that, in the embodiment of the present application, in a case that the server does not find the upgrade patch package corresponding to the current version information of the third application, the server may discard the upgrade patch request message sent by the terminal device. In addition, the server can also send an upgrade patch response message to the terminal device to inform the terminal device that the upgrade patch package corresponding to the current version information of the third application is not found; or the terminal device may not send any message to the terminal device, so that after the terminal device sends the upgrade patch request message, if the upgrade patch package corresponding to the current version information of the third application sent by the server is not received over a certain time, and the upgrade patch response message sent by the server is not received, the terminal device may consider that the upgrade patch package corresponding to the current version information of the third application is not present on the server.

And S116, the terminal equipment receives the upgrade patch package sent by the server.

And S117, the terminal equipment adopts the upgrading patch package to directly upgrade the third application at the member granularity.

After the terminal device receives the upgrade patch package sent by the server, the terminal device may directly upgrade the third application at the member granularity by using the upgrade patch package to repair the original resource of the third application and/or add a new resource of the third application to the third application.

It is to be understood that, in the embodiment of the present application, the third application and the second application may be the same application or may be different applications. Specifically, when the second application is a system application, the third application and the second application may be the same application.

It should be noted that, in the embodiment of the present application, S112 to S117 are exemplified to be executed after S105, and in an actual implementation, S112 to S117 may also be executed after S111, and the embodiment of the present application is not particularly limited.

According to the method for upgrading the application, under the condition that the terminal device determines that the third application can be upgraded, the terminal device sends the upgrade patch request message to the server to request the server for upgrading the patch package, and after the terminal device receives the upgrade patch package sent by the server, the terminal device adopts the upgrade patch package to directly upgrade the third application at the member granularity. On one hand, since the upgrade patch package requested by the terminal device to the server is used for upgrading the third application at the member granularity, compared with the prior art in which the application is upgraded at the class granularity (where one class includes a plurality of members), the upgrade patch package in the embodiment of the present application is smaller, so that resources occupied by the upgrade patch package can be reduced, and the release cycle of the upgrade patch package can be shortened, thereby enabling the third application to be repaired quickly. On the other hand, since the third application is directly upgraded in the embodiment of the present application, compared with the prior art that the application is upgraded by upgrading the operating system of the terminal device, the operating system of the terminal device does not need to be restarted after the third application is upgraded in the embodiment of the present application, so that the third application can be repaired more quickly.

Optionally, the method for loading an application provided in this embodiment of the present application may further include the following steps S118 to S119.

S118, the server searches for the expired upgrade patch package according to the current version information of the third application.

S119, under the condition that the server finds the expired upgrading patch package, the server deletes the expired upgrading patch package.

Optionally, in this embodiment of the application, the server may execute S118-S119 under the trigger of the upgrade patch request message sent by the terminal device (for example, under the trigger of S113 described above); S118-S119 may also be performed periodically with a predefined second time period. Specifically, the determination may be determined according to actual use requirements, and the embodiments of the present application are not limited.
