The following are some explanations of some terms or terms involved in the embodiments of the present application.

Common feature function: refers to a function module that can be used by a number of applications (including system applications and third-party applications) developed by terminal equipment manufacturers and application vendors based on the operating system of the terminal device.

System application: refers to the application that comes with the operating system of the terminal device. System applications can't usually be uninstalled or deleted.

Third-party applications: Applications developed by application vendors, organizations, or individuals. Third-party applications can usually be installed, uninstalled, or deleted.

Class loader: A tool that loads an application's classes into a Java virtual machine before the Java virtual machine runs the application's class. The class loader includes a root class loader (System Class Loader) and a path class loader (Path Class Loader). Among them, by default, the path class loader and the system class loader's parent class loader are root class loaders. In the software development process, the developer can modify the parent class loader of the path class loader according to the actual use requirement. For example, in the embodiment of the present application, the parent class loader of the path class loader can be set as the system class loader.

System upgrade patch: refers to the compressed package after the application installation package set based on the specific version is packaged.

Upgrade patch package: refers to the zip file generated by members of each / some classes (each class includes multiple members) after the application updates (including repairs and additions). The upgraded patch takes up less space than the system upgrade patch, or the upgrade patch consumes less resources than the system upgrade patch.

At present, since application vendors usually package common feature functions into applications, if multiple applications in the terminal device use the same common feature function, the public feature function may be used by the terminal device during the process of starting these applications. The operating system is repeatedly loaded multiple times, so that the memory usage of the terminal device is relatively high, thereby affecting the operating system performance of the terminal device.

In addition, when upgrading the application, the application installation package of the repair problem and the application package of the newly added function are packaged into a system upgrade package to upgrade the operating system of the terminal device, that is, the system upgrade package may be It contains multiple application installation packages, and each application installation package is applied in the class granularity upgrade.

After the upgrade patch is sent by the server, the terminal device adopts the upgrade patch package and directly upgrades the application at the member granularity. On the one hand, since the upgrade patch package requested by the terminal device to the server is used to upgrade the application at the member granularity, the present application is compared with the prior art in the class granularity (one class includes multiple members) upgrade application. The upgrade patch package in the embodiment 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, so that the application can be quickly repaired. On the other hand, in the embodiment of the present application, the application of the terminal device is directly upgraded.

As shown in the common feature list shown in Table 1, in actual implementation, Table 1 may only include the identifier of the application, that is, the column of the common feature in Table 1 is an explanation of the common feature function implemented by the system application. In actual implementation, it is possible to pre-define which common feature functions are specifically implemented by each application. In this way, the terminal device can determine that the application is an application that implements a common feature function by reading an identifier of an application in the predefined common feature function list; or when the terminal device scans an application, if the terminal device is in a predefined The identifier of the application is found in the public feature function list, and the terminal device can determine that the application is an application that implements a common feature function.

Exemplarily, in conjunction with Table 1, taking S103 to perform after S102 as an example, assuming that the common feature function is the positioning function implemented by APP3, when the terminal device scans APP3, if the terminal device finds the identifier of APP3 in Table 1, for example APP3), then the terminal device can determine that APP3 is an application that implements common feature functions. Specifically, in the process of scanning the APP3, the terminal device can determine that the APP3 is specifically used to implement the positioning function by parsing each resource and each attribute of the APP3.

It can be understood that, in the embodiment of the present application, the determining method of the other common characteristic functions in the foregoing Table 1 may be similar to the determining method of the APP3 listed above, and will not be enumerated here.

Optionally, in the embodiment of the present application, the identifier of the foregoing first application is capable of uniquely identifying the first application. The identifier of the first application may be the name of the first application, or the address installed by the first application, and may also be other numbers, Chinese characters, letters, characters, strings, serial numbers, etc. that can uniquely identify the first application. One or more combinations. Specifically, it can be set according to the actual use requirement, and the embodiment of the present application is not limited.

(3) The terminal device reads the first attribute of the first application, where the first attribute is used to indicate whether the first application is an application that implements a common feature function; and the first attribute indicates that the first application is an application that implements a common feature function. The terminal device determines that the first application is an application that implements a common feature function. In a case where the first attribute indicates that the first application is not an application that implements a common feature function, the terminal device determines that the first application is not an application that implements a common feature function.

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

In this embodiment of the present application, each application has a plurality of attributes, wherein the first one of the multiple attributes may be used to indicate whether the application is an application that implements a common feature function. In this way, the terminal device can read each by reading The first attribute used determines whether the read application is an application that implements a common feature function.

Optionally, in the first application in the embodiment of the present application, the first attribute may be a resource attribute of the first application, and the resource library attribute may be shared by each application. The first application's resource library attribute can be set to indicate whether the first application is an application that implements a common feature function.

Specifically, the resource library attribute includes a name field. The embodiment of the present application may set the name field in the resource library attribute to the name of the application, so that the application can be shared by other applications, that is, the application is made. The implemented functionality is a common feature. That is, the first application in the embodiment of the present application is used as an example, and the name field in the resource library attribute of the first application may be set as the name of the first application, so that the first application can be shared by other applications, even if The function implemented by the first application is a common feature function.

In the embodiment of the present application, after the terminal device scans an application, the path class loader is generally used to load the application by default. Therefore, 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 common. The application does not need to be globally loaded, and the terminal device can load the first application into the memory of the terminal device by using the path class loader by default.

It should be noted that, in this embodiment of the present application, each application includes multiple classes, and the first application is used as an example. The first application also includes multiple classes. The terminal device uses the path class loader to load the first application into the application. The memory of the terminal device means that the terminal device loads the class name of the multiple classes of the first application into the memory of the terminal device (this process is also called preloading), and when the first application is specifically used, the terminal device will be multiple. The contents of the class are loaded into memory.

S104. The terminal device loads the first application into the memory of the terminal device by using a system class loader.

In the embodiment of the present application, the content loaded by the system class loader is usually an operating system level, that is, the content loaded by the system class loader can be shared by all the applications under the operating system. Therefore, the embodiment of the present application uses the system class loader to load. The common feature function can make the common feature function that has been loaded shared by all applications in the terminal device, thereby achieving the purpose that the common feature function is globally loaded.

It can be understood that, in S104, the terminal device also loads the class name of the multiple classes of the first application into 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 only Load the contents of multiple classes into memory.

It can be understood that, in the embodiment of the present application, the foregoing S102-S104 is described by taking an example of the terminal device scanning and determining an application that implements a common characteristic function (that is, the first application described above) as an example, and implementing other common characteristic functions in the terminal device.

Since the first application loaded by the system class loader is an operating system level application, other applications in the operating system can share the first application that has been loaded into the memory, so that other applications sharing the first application are shared. After the startup, the first application in the memory can be directly invoked, and the first application does not need to be loaded when starting other applications sharing the first application, so that the first application can be avoided when starting other applications sharing the first application. The application is repeatedly loaded multiple times, which can reduce the memory usage of the terminal device and improve the operating system performance of the terminal device.

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

Exemplarily, taking the common characteristic function listed in the above S103 as an example, assuming that the first application implements a common special The sexual function is a beauty function, and the second application can be any application that uses the beauty function, for example, the second application can be a camera application, a health application, or a sports application.

Assuming that the public feature function implemented by the first application is a voice function, the second application may be any application that uses the voice function, for example, the second application may be a map application, a media application, a browser application, or a social application. .

It can be understood that, in the embodiment of the present application, some of the second applications listed in the foregoing examples may be system applications or third party applications. For example, the camera application may be a system camera application or a third party camera application; the map application may 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. The application of the application, etc., may be determined according to the actual situation, and the embodiment of the present application is not limited.

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

In the embodiment of the present application, according to the parental delegation mechanism of the class loading, the terminal device first uses the system class loader to find the class to be loaded when the class is loaded, and if the system class loader does not find the class to be loaded, then the application class The path class loader finds and loads. According to this principle, in the above S104, the terminal device is loaded by the system class loader when the first application is preloaded. Therefore, after the second application is started, the terminal device can find the first application based on the second application, even if In the embodiment of the present application, after the path device loader of the second application is created, the terminal device may use the path class after the second application is configured to provide the first application with the common application function. The loader's parent class loader is set to system class loading So that the terminal device can directly load the second application into the memory of the terminal device by using the system class loader according to the parental delegation mechanism of the class loading. That is, as described in the following S111, the terminal device loads the second application into the memory of the terminal device by using the system class loader.

S111. The terminal device loads the second application into the memory of the terminal device by using a system class loader.

In the embodiment of the present application, the terminal device uses the system class loader to load the second application into the memory of the terminal device, so that after the second application is started, the terminal device can find the first application based on the second application. The system class loader is loaded into the memory of the terminal device, that is, the second application can normally provide the user with the common feature function implemented by the first application by calling the first application.

Exemplarily, the above-mentioned beauty function is still implemented by the first application, and the second application is a camera application, and the terminal device uses the system class loader to load the first application that implements the beauty function and the camera application that invokes the first application. Afterwards, the terminal device can find the first application that implements the beauty function based on the camera-type application, thereby ensuring that the camera-type 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 will be described below by taking FIG. 4 as an example. As shown in FIG. 4, it is a schematic diagram of relationships between various class loaders in a terminal device provided by an embodiment of the present application.

The path class loader is used to load normal applications (for example, music.apk and Bluetooth.apk in Figure 4, music.apk for music installation package in Android OS, Bluetooth.apk for Bluetooth installation package in Android OS) and System services (such as services.jar in Figure 4, services.jar represents a service in the Android operating system) and so on. The system class loader is used to load an application that implements the common feature function, such as the first application in the embodiment of the present application (for example, feature.apk in FIG. 4, feature.apk represents a common feature function in the Android operating system). The root class loader is used to load the system framework of the Android operating system, such as the core library layer in the Android operating system (for example, libcore.jar in FIG. 4) and the framework layer (for example, the framework.jar in FIG. 4).

Optionally, in conjunction with FIG. 2, after the foregoing S105, the method for loading an application provided by the embodiment of the present application may further include the following S112-S117.

S112. The terminal device sends an upgrade patch request message to the server.

S113. The server receives an upgrade patch request message sent by the terminal device.

In the embodiment of the present application, a possible implementation manner is: when the terminal device determines that the application running in the terminal device is abnormal, for example, the third application in the embodiment of the present application is abnormal, the terminal device determines to upgrade the third application. The terminal device can trigger execution of S112-S117.

Another possible implementation manner is that the terminal device can periodically check whether there is an application on the server, such as the upgrade patch package of the third application in the embodiment of the present application, when the terminal device determines the server. When there is an upgrade patch package of the third application, the terminal device determines to upgrade the third application, and the terminal device may trigger execution of S112-S117.

Optionally, in another possible implementation manner, the predefined first time may be any predefined time, such as one day, one week, or one month, and the like, which may be defined according to actual usage requirements. Not limited.

The upgrade patch request message is used to request an upgrade patch package from the server. The upgrade patch package is used to directly upgrade the third application at the member granularity, and the third application is a system application in the terminal device.

The third application in the embodiment of the present application mainly refers to a system application, because the third-party application can be downloaded from the application store.

In the embodiment of the present application, each application includes multiple classes, and each class includes multiple members. The above upgrade patch package may include at least one member, wherein when the number of members is plural, the plurality of members may be members of different classes. In the embodiment of the present application, when the third application is upgraded by using the foregoing upgrade package, the third application may be upgraded in the member granularity, that is, only the members that need to be upgraded may be upgraded, and the entire class of the members is not required. Upgrade. For example, a member of the third application that needs to be repaired may be replaced with one member of the upgrade patch package, and/or a member of the upgrade patch package may be added to the third application. The upgrade patch package in the embodiment of the present application is smaller than that in the prior art, and the resource occupied by the upgrade patch package can be reduced, and the release period of the upgrade patch package can be shortened, thereby making the third The app can be fixed quickly.

In addition, since the third application is directly upgraded in the embodiment of the present application, the operating system of the terminal device is not required to be restarted after upgrading the third application in the embodiment of the present application. So that the third application can be repaired more quickly.

Optionally, in the embodiment of the present 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, it can be determined according to the actual use requirement, and the embodiment of the present application is not limited.

Optionally, in the embodiment of the present application, the upgrade patch package may include at least one resource and at least one identifier. Each identifier is used to uniquely identify a resource. The at least one resource includes at least one of the first resource and the second resource, where the first resource is used to repair the original resource of the third application (the first resource may also be referred to as the repair resource of the third application), and the second resource is the first resource. The newly added resources of the three applications (that is, the second resource is a new resource based on the original resources of the third application).

It should be noted that, in the embodiment of the present application, the identifier used to identify 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 the embodiment of the present application, the foregoing resource may be a combination of one or more of a number, a text (including characters and letters, etc.), a picture, and a file (including files in various formats). Specifically, it can be determined according to the actual use requirement, and the embodiment of the present application is not limited.

The identifier used for uniquely identifying the resource may be the name of the resource, or the storage address of the resource, or one or more of other numbers, Chinese characters, letters, characters, strings, and serial numbers that can uniquely identify the resource. Combination of one. Specifically, it can be determined according to the actual use requirement, and the embodiment of the present application is not limited.

Exemplarily, the third application is taken as an example. As shown in FIG. 5, the schematic diagram of generating an idmap provided by the embodiment of the present application (as shown in FIG. 5 only shows the identifier for uniquely identifying the resource, due to the particularity of the resource, The resource is not shown). In FIG. 5, part A represents a code for identifying an identifier of an original resource in the third application; and part B represents an identifier of the new resource for identifying the repair resource of the third application and the third application in the upgrade patch package. The code, specifically, B1 represents the code of the identification of the repair resource of the third application, and B2 represents the code of the identification 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 upgrade patch package is adopted, when the member granularity is upgraded to the third application, the third application is repaired by generating and extending the idmap and executing the code in the idmap. The resource replaces the original resource of the third application, and adds the new resource of the third application to the other resource in the third application. For example, as shown in part C of FIG. 5, the idmap is generated and extended. In the idmap, by performing C1 and C3, it is possible to replace A1 with B1 in part A, and by adding C2 and C3, it is possible to add B2 in part A. On the one hand, since the upgrade patch package requested by the terminal device to the server is used to upgrade the third application in the granularity of members (for example, B1 and B2 as shown in FIG. 5), therefore, in the prior art, the class granularity (a class) Compared with the upgrade application, the upgrade package in the embodiment of the present application is smaller, so that the resources occupied by the upgrade package can be reduced, and the release period of the upgrade package can be shortened, so that the third application can be quickly repair. On the other hand, the third application is directly upgraded in the embodiment of the present application. Therefore, the upgrade of the third application is not required to restart the terminal after the third application is upgraded in the embodiment of the present application. The operating system, so that the third application can be fixed more quickly.

It can be understood that in the above FIG. 5, if A is considered to be a class, then A1, B1 and B2 can be considered as 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 this embodiment, the mapping relationship between the version information of multiple applications and multiple upgrade patch packages may be stored on the server. The mapping relationship between the version information of the plurality of applications and the plurality of upgraded patch packages may include a mapping relationship between the current version information of the third application and the upgrade patch package. In this way, after the server receives the upgrade patch request message sent by the terminal device, the server may search for the upgrade patch package corresponding to the current version information on the server according to the current version information of the third application in the upgrade patch request message.

Exemplarily, the current version information of the third application is a combination of the numbers and letters listed in the above S113, and the mapping relationship between the current version information of the third application and the upgraded patch package is described in conjunction with Table 2.

Table 2

第三应用的当前版本信息Current version information of the third application	升级补丁包Upgrade patch
V1V1	升级补丁包1Upgrade patch 1
V2V2	升级补丁包2Upgrade patch 2
V3V3	升级补丁包3Upgrade patch 3
V4V4	升级补丁包4Upgrade patch 4

As shown in Table 2, if the current version information of the third application carried in the upgrade patch request message received by the server is V2, the server may look up the upgrade patch package corresponding to V2 in Table 2, for example, the server is in Table 2. The upgrade patch package 2 corresponding to V2 is found, and then the server sends the upgrade patch package 2 to the terminal device, so that the terminal device upgrades the third application by using the upgrade patch package 2. In this way, it is possible to avoid an error that occurs when the third application is upgraded because the version does not correspond.

S115. If the server finds the upgrade patch package corresponding to the current version information, the server sends the upgrade patch package to the terminal device.

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. And the server may further send an upgrade patch response message to the terminal device to notify 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 packet corresponding to the current version information of the third application sent by the server is not received, the server does not receive the server. The upgrade patch response message is sent, and the terminal device can consider that there is no upgrade patch package corresponding to the current version information of the third application on the server.

S116. The terminal device receives the upgrade patch package sent by the server.

S117. The terminal device adopts the upgrade patch package, and directly upgrades the third application in the member granularity.

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

It can 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 the embodiment of the present application is described as an example after S112-S117 is executed after S105. In actual implementation, S112-S117 may also be executed after S111, which is not specifically limited in this embodiment.

In the method for upgrading an application provided by the embodiment of the present application, in a case where the terminal device determines that the third application can be upgraded, the terminal device sends an upgrade patch request message to the server to request an upgrade patch package from the server, and the terminal device receives the server to send the upgrade patch package. After the upgrade package is upgraded, the terminal device adopts the upgrade patch package to directly upgrade the third application at the member granularity. On the one hand, since the upgrade patch package requested by the terminal device to the server is used to upgrade the third application at the member granularity, compared with the prior art in the class granularity (a class includes multiple members), the upgrade application is compared. The upgrade patch package in the embodiment of the present application is smaller. In this way, the resources occupied by the upgrade patch package can be reduced, and the release period of the upgrade patch package can be shortened, so that the third application can be quickly repaired. On the other hand, in the embodiment of the present application, the third application is directly upgraded. Therefore, the upgrade of the third application is not required to restart the terminal after the third application is upgraded in the embodiment of the present application.
