The implementation principle of the technical solution of the embodiment of the present application is described below in conjunction with fig. 1B, including the following two possible implementations.

One possible implementation manner is that after a first application (the first application may be any application) in the application program layer is started, if it is determined that an application resource of a second application needs to be accessed, a package management service in a lower layer, that is, an application program framework layer, may be called, for example, the application program framework layer includes an API interface, the first application sends a first access request to the package management service in the application program framework layer through the API interface, after receiving the first access request, the package management service obtains an application resource of the second application in a resource database, and then returns the application resource of the second application to the first application through the API interface.

In another possible implementation manner, after a first application (the first application may be any application) in the application program layer is started, if it is determined that an application resource of the second application needs to be accessed, a process management service in the system library may be called, for example, the system library includes an API interface, the first application sends a first access request to the process management service in the system library through the API interface, and after the process management service receives the first access request, a storage path of the resource database is mounted on a process of the first application, so that the first application may obtain the application resource of the second application from the resource database.

Fig. 1C illustrates each module included in an application layer and each module included in an application framework layer in a software architecture block diagram of an electronic device according to an embodiment of the present application.

The application layer of the electronic device includes a display module and other modules. The display module is used for displaying application resources of the installed application on the user interface, and the installed application can comprise two forms of system application and common application. The system application is an application carried by the electronic equipment when leaving the factory and is used for guaranteeing the basic operation of the electronic equipment. A general application is an application provided by each developer for realizing a certain function. In the case that the installed application is a system application, the application resources of the installed application include a system font style, a system language type, and the like, for example, the system font style is a regular script, and the system language type is chinese. In the case where the installed application is a normal application, the application resources of the installed application include an application identification and an application icon.

The application framework layer of the electronic device comprises a downloading module, an installing module, an unloading module and other modules. The downloading module is used for downloading application program packages of various applications from an application market or other channels. The installation module is used for installing each application program according to the application program package of each application. Wherein the application program package of any application comprises the application resource of the application. The uninstalling module is used for uninstalling each installed application and deleting the corresponding application program package.

The scenario in which the first application obtains the application resources of other applications is described in detail below by taking the first application as an example, where the first application may be any application installed in the electronic device.

In the case that the first application is a system application, if the first application is a desktop display application, the desktop display application needs to acquire application resources of a plurality of common applications and display the application resources on a desktop of the electronic device. For example, as shown in fig. 2, the desktop display application obtains the application resource of the WeChat, and displays the application identifier of the WeChat (i.e., the "WeChat") and the application icon of the WeChat on the desktop of the electronic device.

If the first application is a common application, if the user needs to share the content of the first application, and the user clicks the sharing button of the first application, the first application obtains application resources of other common applications, displays the application resources of other common applications in the sharing interface of the first application, and facilitates the user to select a target application from the displayed other common applications to share the content of the first application.

For example, when a user listens to a song using internet music, as shown in fig. 3 (a), if the user clicks the sharing button, the internet music pops up the sharing interface, as shown in fig. 3 (b), where the sharing interface includes an icon and an identifier of the microblog, an icon and an identifier of a friend circle of the WeChat, and an icon and an identifier of a friend of the WeChat, the user can select any application from the sharing interface to share the song.

For convenience of description, taking the second application as an example, how the first application obtains the application resource of the second application is explained below, where the first application is a system application or a general application, and the second application is a general application. Generally, when determining that an application resource of a second application needs to be acquired, the first application may read an application package of the second application, acquire an application identifier and an application icon of the second application from the application package of the second application, parse the application icon of the second application to obtain an application icon in a binary stream form, and finally display the application identifier and the application icon of the second application on a desktop of the electronic device or a sharing interface of the first application according to the acquired application identifier and the application icon in the binary stream form.

In the above resource access process, since the first application can directly read the application package of the second application, if privacy data exists in the application package, the disclosure of the privacy data in the second application is easily caused.

In order to solve the above problems, the embodiments of the present application propose a resource access method that can be implemented on the electronic device 100 having the above-described hardware structure. For the electronic device, the application provides a new software structure block diagram, an application program layer and an application program framework layer in the software structure block diagram are shown in fig. 4, and the application program layer of the electronic device comprises a display module and other modules. The display module is used for displaying application resources of the installed application on the user interface.

The application program framework layer of the electronic equipment comprises a downloading module, an installing module, an analyzing module, a message processing module, a resource database module, a permission module, an unloading module and other modules. The downloading module is used for downloading application packages of various applications from an application market or other channels, and the downloaded application packages can be stored in a second storage space of the electronic device, wherein the second storage space is configured to be accessible by only the second application. The installation module is used for installing each application program according to the application program package of each application. Wherein the application program package of any application comprises the application resource of the application. The analysis module is used for analyzing the application resource from the application program package, storing the application resource into the resource database module, and after the storage of the application resource is completed, sending a storage completion message by the message processing module. The resource database is located in a first storage space on the electronic device, the first storage space being different from the second storage space. The uninstalling module is used for uninstalling each installed application and deleting the corresponding application program package.

The electronic equipment comprises an operating system, and the operating system can provide services such as installation, upgrading and unloading of common applications through a display module in an application program layer, a downloading module, an installation module, an analysis module, a message processing module, a resource database module, a permission module and an unloading module in an application program framework layer. The operating system in the electronic device may be a hong system, IOS system, android system, etc., without limitation.

In order to facilitate the detailed description of the installation, upgrading and uninstalling of the common application, the second application is taken as the common application, and the installation, upgrading and uninstalling of the second application is described in detail.

In a possible implementation manner, when the second application generates the first type of application update, the operating system may update the application resources of the second application in the resource database in addition to implementing the application update of the second application, where the first type of application update includes any one of installation, upgrading and uninstallation.

The installation or upgrade of the second application, explained in detail below, may include the following steps as shown in fig. 5.

S501, when the second application is installed or upgraded, the operating system acquires an application program package of the second application.

In the embodiment of the present application, the operating system performing the step of fig. 5 may be a packet management service in the hong-mo system, or may be a service in another operating system, which is not limited herein.

In one possible implementation, the operating system may obtain an application package of the second application through the download module, and store the application package of the second application in the second storage space of the electronic device.

S502, the operating system acquires application resources of the second application from an application program package of the second application. The application resources of the second application comprise application identifiers and application icons of the second application.

In the embodiment of the application, the operating system may acquire the application resource of the second application from the application program package of the second application through the parsing module.

Optionally, the operating system may further parse the application resource of the second application through the parsing module to obtain an application resource in a binary stream form.

S503, the operating system updates the resource database based on the application identification of the second application and the application resource.

The operating system searches the application identifier of the second application in the resource database, and if the application identifier of the second application does not exist in the resource database, the operating system directly adds the application identifier of the second application and the application resource into the resource database.

If the application identifier of the second application exists in the resource database, replacing the application identifier and the application resource of the second application existing in the resource database by adopting the application identifier and the application resource of the second application acquired at the time.

It should be appreciated that the application identification and application resources of the second application may be stored in a key-value manner, such as < application identification of the second application, application resources of the second application >.

When the operating system determines that the application identifier of the second application exists in the resource database, the operating system can also search the application identifier of the second application in the cache of the operating system, and if the application identifier of the second application exists in the cache of the operating system, the operating system replaces the application identifier and the application resource of the second application existing in the cache of the operating system by adopting the acquired application identifier and application resource of the second application. If the application identifier of the second application does not exist in the cache of the operating system, the operating system may not perform any processing.

It should be appreciated that the application resources of the second application in the resource database may be in the form of a binary stream. The application resources of the second application in the cache of the operating system may be in the form of a binary stream.

After updating the resource database, the operating system may further determine a resource access right of the second application, and add the application identifier of the second application and the resource access right of the second application to the right module.

And if the second application applies the access authority of the resource database to the operating system and the application is successful, the resource access authority of the second application is allowed to be accessed. If the second application applies the access authority of the resource database to the operating system but fails, the resource access authority of the second application is not allowed to be accessed. And if the second application does not apply the access authority of the resource database to the operating system, the resource access authority of the second application is not allowed to be accessed.

It should be appreciated that the application identifier of the second application and the resource access rights of the second application may be stored in a key-value manner, for example, if the resource access rights of the second application are allowed access, the rights module may store < the application identifier of the second application, allowed access >.

S504, the operating system installs or upgrades the second application according to the application program package of the second application.

In the embodiment of the application, the operating system may implement installation or upgrading of the second application by using an application program package of the second application through the installation module.

The execution sequence of S502 and S504 is not sequential.

In the method, when the second application is installed or upgraded, the operating system can update the resource database based on the application identifier and the application resource of the second application, so that the application resource of the second application can be directly acquired from the resource database.

Optionally, the user performs a first operation on the electronic device, where the first operation may include the user determining an application identifier of the second application, the user determining the number of resources to be updated, and so on. The electronic device may generate a first operation request based on a first operation of the user. The first operation request is used for requesting part of resources of the second application, and the first operation request can include an application identifier of the second application and the number of resources to be updated. The operating system receives the first operation request and updates part of the resources of the second application to the resource database according to the first operation request. The part of the resources of the second application are determined according to the application identification of the second application in the first operation request and the quantity of the resources to be updated. The operating system can acquire the application resources corresponding to the number of the resources to be updated from the application program package of the second application, and the application resources are used as part of the resources of the second application. Wherein the partial resources of the second application may be resources that have not been added to the resource database.

For example, the first operation request includes an application identifier of the second application and the number of resources to be updated 2, and after receiving the first operation request, the operating system obtains 2 resources that are not added to the resource database from the application package of the second application, and adds the resources as part of the resources of the second application to the resource database.

By the method, the application resources of the second application can be dynamically added to the resource database, so that the flexibility is enhanced.

The unloading of the second application is explained in detail below, and may include the following steps as shown in fig. 6.

S601, when the second application is unloaded, the operating system deletes the application identification and the application resource of the second application from the resource database.

In the embodiment of the present application, the operating system performing the step of fig. 6 may be a packet management service in the hong-mo system, or may be a service in another operating system, which is not limited herein.

In one possible implementation, the operating system may also delete the application identifier of the second application and the application resource from the cache of the operating system.

In one possible implementation, the operating system may further delete the application identifier of the second application and the resource access rights of the second application from the rights module.

S602, the operating system uninstalls the second application according to the identification of the second application.

In one possible implementation, the operating system may offload the second application through the offload module.

It should be understood that, in S601, the operating system deletes the identifier of the second application and the application resource from the resource database, and the execution order of unloading the second application from the operating system in S602 is not sequential.

In the method, when the second application is unloaded, the operating system deletes the application identifier and the application resource of the second application from the resource database, so that the subsequent failure to acquire the application resource of the second application from the resource database is ensured.

In order to facilitate the detailed description of the system theme switching or the system language switching corresponding to the system application, the second application is used as the system application, and the system theme switching or the system language switching corresponding to the second application is described in detail.

In a possible implementation manner, when the second application generates a second type of application update, the operating system may update the application resources of the third application stored in the resource database, where the second type of application update includes any one of a system theme switch and a system language switch. The third application is any common application, and the application resources of the third application comprise application identifiers and application icons of the third application.

The second type of application update of the second application, explained in detail below, may include the following steps as shown in fig. 7:

and S701, when the second application generates the second type of application update, the operating system acquires an application program package of the second application.

In the embodiment of the present application, the operating system performing the step of fig. 7 may be a packet management service in the hong-mo system, or may be a service in another operating system, which is not limited herein.

S702, the operating system acquires application resources of the second application from the application program package of the second application.

In the case that the second application performs system theme switching, the application resources of the second application include a system font style and the like, for example, the system font style is a regular script; in the case that the second application is subjected to system language switching, the application resources of the second application include a system language type and the like, for example, the system language type is chinese.

S703, the operating system updates the application resources of the third application stored in the resource database based on the application resources of the second application.

In a possible implementation manner, in the case that the second application performs system theme switching, the operating system updates the application identifier and the application icon of the third application stored in the resource database by adopting a system font style and the like. For example, the application identifier of the third application stored in the resource database is Song Ti type, and after the second application performs system theme switching, the application identifier of the third application stored in the resource database is regular script type.

And under the condition that the second application is subjected to system language switching, the operating system updates the application identifier and the application icon of the third application stored in the resource database by adopting the system language type. For example, the application identifier of the third application stored in the resource database is of english type, and the application identifier of the third application stored in the resource database is of chinese type after the second application is subjected to system language switching.

Fig. 8 is a schematic flow chart illustrating a resource access method according to an embodiment of the present application. The resource access method may include the steps of:

s801, a first application determines that application resources of a second application need to be accessed.

In a possible implementation manner, after determining that an application resource of the second application needs to be accessed, the first application may generate a first access request, where the first access request is used to request the application resource of the second application, and the first access request includes an application identifier of the second application.

It should be understood that the first application may be a system application, and may also be a general application, which is not limited herein. The second application is a general application.

S802, the first application acquires application resources of the second application from a resource database.

In a possible implementation manner, the first application may obtain the application resource of the second application from the resource database according to the application identifier of the second application. After the first application obtains the application resource of the second application, the application resource of the second application can be displayed.

In the embodiment of the application, the resource database includes at least one application identifier and application resources of at least one application, and the application resources of each application in the resource database are obtained from an application program package of each application. The steps in fig. 5 have been described in detail as to how the application resources of each application are added to the resource database, and are not described in detail herein.

When the first application does not acquire the application resources of the second application from the resource database, the first application outputs prompt information, and the prompt information is used for prompting that the application resources of the second application cannot be accessed.

In this embodiment of the present application, the first application obtains the application resource of the second application from the resource database, which may include the following two possible embodiments:

a first possible implementation may include the following steps as shown in fig. 9:

s901, the first application sends a first access request. Accordingly, the operating system obtains a first access request of the first application.

In the embodiment of the present application, the operating system performing the step of fig. 9 may be a packet management service in the hong-mo system, or may be a service in another operating system, which is not limited herein.

In a possible implementation manner, after obtaining the first access request, the operating system obtains the resource access right of the first application from the right module according to the identifier of the first application, and if the resource access right of the first application is allowed to be accessed, the operating system executes S902; if the resource access authority of the first application is not allowed to be accessed, the operating system does not perform any processing.

S902, the operating system determines application resources of the second application from the resource database according to the application identification of the second application.

In the first embodiment, the operating system may directly obtain the application resource of the second application from the resource database according to the application identifier of the second application. Specifically, the operating system sends a resource query request to the resource database, wherein the resource query request includes an application identifier of the second application. And the resource database determines the application resources of the second application according to the application identification of the second application in the resource query request, and sends the application resources of the second application to the operating system.

In the second embodiment, the operating system may determine, according to the application identifier of the second application, whether an application resource of the second application exists in the cache of the operating system. If the cache of the operating system does not contain the application resource of the second application, the operating system determines the application resource of the second application from the resource database; if the application resource of the second application exists in the cache of the operating system, the operating system determines the application resource of the second application from the cache.

In the method, if the application resource of the second application exists in the cache of the operating system, the application resource of the second application can be directly obtained from the cache without searching in the resource database, and the efficiency of obtaining the application resource of the second application can be improved.

S903, the operating system sends the application resource of the second application to the first application.

After the first application acquires the application resource of the second application, if the application resource of the second application is in a binary stream form, the application resource can be directly displayed without analysis, and the display speed of the application resource can be effectively improved.

A second possible implementation may include the following steps as shown in fig. 10:

S1001, the first application sends a first access request. Accordingly, the operating system obtains a first access request of the first application.

In the embodiment of the present application, the operating system performing the step of fig. 10 may be a process management service in the hong-mo system, or may be a service in another operating system, which is not limited herein.

In a possible implementation manner, after obtaining the first access request, the operating system obtains the resource access right of the first application from the right module according to the identifier of the first application, and if the resource access right of the first application is allowed to be accessed, the operating system executes S1002; if the resource access authority of the first application is not allowed to be accessed, the operating system does not perform any processing.

S1002, the operating system mounts the storage path of the resource database to the process corresponding to the first access request.

The operating system mounts the storage path of the resource database under the process corresponding to the first access request, so that the first application can access the resource database directly according to the storage path of the resource database.

S1003, the first application obtains application resources of the second application from the resource database based on the storage path of the resource database.

In the first embodiment, the first application may directly obtain the application resource of the second application from the resource database according to the application identifier of the second application.

In the second embodiment, the first application may determine, according to the application identifier of the second application, whether an application resource of the second application exists in the cache of the operating system. If the cache of the operating system does not contain the application resource of the second application, the first application determines the application resource of the second application from the resource database; if the application resources of the second application exist in the cache of the operating system, the first application determines the application resources of the second application from the cache.

In the method, the first application can acquire the application resources of the second application from the resource database instead of acquiring the application program package of the second application, so that the private data leakage in the application program package of the second application can be effectively avoided. In addition, the problem of overlarge occupied memory resources can be effectively avoided because the application program package of the second application is not required to be loaded.
