Detailed ways

The technical solutions of the present invention are further described below with reference to the accompanying drawings and through specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, the drawings only show some but not all structures related to the present invention.

FIG. 1 is a schematic flowchart of a data deletion method for a multi-open application provided by an embodiment of the present invention. The method is suitable for simultaneously deleting junk data such as buffer data, spam short messages and spam emails of each application in the same multi-open application set, and the method can be executed by a data deletion device or a mobile terminal of the multi-open application. The above-mentioned apparatus for deleting data of multiple open applications may be implemented by means of software and/or hardware, and the apparatus may be configured in a mobile terminal.

As shown in Figure 1, the method of this embodiment includes:

Step 110: Detect in real time an operation event on each multi-open application set.

Among them, the multi-open application set includes the main application and the avatar application corresponding to the main application; the operation event includes the creation event of the main application in the multi-open application set, the start/close event of any application in the multi-open application set, Uninstall and delete events for any application in the multi-open application set, and data deletion events for any application in the multi-open application set.

Step 120: When detecting the data deletion event of the target application in the multi-open application set, determine the associated application of the target application.

The associated application is an application corresponding to the target application in the multi-open application set.

In this embodiment, there may be many ways to implement the multi-open application set, which is not specifically limited in this embodiment. For example, different versions of applications can be installed separately, one version is used as the main application, and the other versions are used as separate applications, wherein, the installation package (APK) file of the application can be modified by decompilation, and then the modified APK file can be installed. Install different versions of the same application; another example, it can be implemented by applying a third-party multi-open assistant software that simulates user space and dynamic loading technology; another example, it can be implemented by modifying the system mechanism.

Preferably, in this embodiment, the multi-open application set is implemented based on a multi-user mechanism, wherein the multi-user mechanism may specifically include a multi-user mechanism supported by the operating system in the smart terminal, such as the multi-user mechanism of the Android system and the mobile phone. Window (Windows Phone, WP) operating system's multi-user mechanism, etc.

Exemplarily, the data deletion event of the target application may be a user's data deletion instruction to the target application, or the data volume of the target data reaches a preset storage threshold. Exemplarily, the user can selectively delete the data of the target application at any time, and when the mobile terminal detects the user's instruction to delete the target data of the target application, the associated application of the target application is determined; or, the mobile terminal detects the target under the current user in real time. The data volume of the target data of the application is determined when the data volume of the target data reaches a preset storage threshold, wherein the preset storage threshold is set based on the stable operation of each multi-open application.

In addition, in this implementation, determining the associated application of the target application may include:

A. Obtain the application ID of the target application.

The application identifier includes an application name. In order to distinguish different multi-open applications, the main application and the secondary application may have the same application name, and to distinguish the main application and the secondary application, an identifier may be set before the application name. For example, if the main application is WeChat, and the application name can be weixin, in this case, the application name of a clone application can be *weixin.

B. Determine the application corresponding to the application identifier with the application name of the target application as the associated application of the target application.

Step 130 , delete the target data corresponding to the data deletion event in the target application and the associated application.

This embodiment is based on the multi-user mechanism of the Android system, and for user data management, the mobile terminal of this embodiment can perform the following operations:

1. The application avatar management module will create a avatar application in the new user space. When creating a avatar application, it will create a data file path for the avatar application under the new user path.

Exemplarily, when the first avatar application is created, the application avatar management module creates a new user through the multi-user service UserManagerServcie. Based on the above multi-user mechanism, the new user is automatically assigned userId as u10, and creates a data file path data for it. /user/u10, for example, if the application is WeChat, the application avatar management module will create a data file path data/user/u10/weixin for the avatar application, which is used to save the operation data of the avatar application at runtime.

2. When the user operates in the main application, the application avatar management module will save the generated data in the main application path of the main user; when the user operates the avatar application, the application avatar management module will save the generated data in the main application path. From the user's avatar application path.

3. The application avatar management module can delete or modify the data of the avatar application across users, so as to realize the control of the avatar application data.

Exemplarily, when the main application and its avatar application have related data that needs to be saved, the application avatar management module can save the data in the path of the avatar application; The application avatar management module modifies the data to the avatar application path, so that this setting is also available in the avatar application; the application avatar management module can log in to different accounts by managing the data of the main application and the avatar application. Freely access data in data file paths under different users.

4. When the avatar application is uninstalled, the application avatar management module will clear the data under the avatar application path.

5. The application avatar management module can monitor the changes of data files, such as data addition, deletion and modification operations, and respond to these operations.

Exemplarily, when the data of the main application changes, the avatar application that needs to be synchronized will also make corresponding changes to the data according to the application avatar management module.

In step 130 of this embodiment, the target data may be junk data such as cached data, junk short messages and junk mails. The target data deleted by the target application is monitored according to the data deletion event, and the application avatar management module deletes the corresponding target data of the associated application according to the path of the associated application under each user.

The data deletion method for a multi-open application provided by the embodiment of the present invention, when a data deletion event for a target application in a multi-open application set is detected, by deleting the target data of the target application, the target corresponding to the associated application can be deleted at the same time. It is not necessary to switch to a different user to delete the target data one by one, which solves the problem of cumbersome operation of deleting multi-open application data, and can delete the data of the main application and the corresponding avatar application conveniently and quickly.

FIG. 2 is a schematic flowchart of another method for deleting data of a multi-open application provided by an embodiment of the present invention. In this embodiment, on the basis of the above-mentioned embodiment, the storage path of the target data is preset, and the target data corresponding to the data deletion event in the step deletion target application and the associated application is optimized as follows: according to the preset cache file subdirectory, garbage The priority of the SMS sub-directory and the spam sub-directory, delete the target data in the sub-directories in descending order of priority; after deleting the target data in any sub-directory, ask whether to continue to delete the target data. As a result, junk data that occupies the largest storage space or is used with zero frequency is preferentially deleted.

Specifically, as shown in FIG. 2 , the data deletion method of the multi-open application of this embodiment includes the following steps:

Step 210: Detect in real time an operation event on each multi-open application set.

Step 220: When a data deletion event of the target application in the multi-open application set is detected, determine the associated application of the target application.

The multi-open application set is implemented based on the multi-user mechanism, including the main application and all the sub-applications corresponding to the main application.

Specifically, the implementation of the multi-open application set based on the multi-user mechanism may include the following contents: the main application is installed under the main user, the secondary application is installed under the secondary user, and the main user includes an access port for operating the secondary application.

In one embodiment, the multi-user implementation mechanism of the present application includes the following logic:

1. Multi-user management

a) The system has a master user by default, the master user can create other multiple new users (slave users), and can delete and manage them;

b) Ordinary users (non-master users) and guest users can be collectively referred to as slave users;

c) The default main user id (identification, Identification) is 0, and other new user ids start from 10 and increase one by one;

d) When switching users, a series of interface switching such as the desktop will be reloaded;

e) The main user can restrict whether other users can make and receive calls and send and receive text messages.

For multi-user management, the master user can manage the slave users, including the creation, deletion and permission setting of slave users. The ID setting starts from the master user, and the IDs of the new slave users are added sequentially. When switching between users, reload Corresponding to a series of interfaces such as the user's desktop.

2. Multi-user installation and uninstallation of applications

a) The application installed by default will be installed to all created users, and the application icon will be visible on the desktop of other users;

b) The application installed by the main user through the file management will not be installed to other users, and the application icon will not be visible on the desktop of other users;

c) The system can specify a userid (user ID) when installing or uninstalling an application, install the specified application to a specified user, or uninstall the application from a specified user. The app can also be installed or uninstalled for all users.

For multi-user installation and uninstallation of applications, the applications installed by default will be installed to all created users (including master users and slave users), and application icons will be generated on the desktops of each user; applications installed under the master user through file management , it is only installed under the master user, and the application icon is generated on the master user's desktop, not under the slave user; the installation/uninstallation of the application can also be based on the user's designation of the user. Installation/uninstallation of apps from users specified under a certain user, some users or all users.

3. User data management

a) User id directory related to system data: stores various system data stores corresponding to users, such as: desktop widget (component) list, setting database, default application startup strategy, etc.

b) User id directory related to application package data: stores the application package directory correspondingly installed by the user. If data is generated by the application operation, the application data is also stored in this directory.

c) System SD card (Secure Digital Memory Card, Secure Digital Memory Card) directory: each user sees his own sdcard directory is different, and can only see his own sdcard directory.

For user data management, under the multi-user implementation mechanism, system data and application-related data under each user are stored in different data storage paths. For example, various system data under a user are stored under a designated first data storage path. , and the application-related data such as the installed application package directory and the application data generated by the application operation are stored in the specified second data storage path; the data storage under each user is independent of each other, and each user can only view their own storage data, such as their own storage data. sdcard directory.

4. User rights management

a) After the application is installed, the various permissions applied by the application (for example: permission to read the storage directory, permission to read and write SMS messages, permission to open the camera, etc.) will be divided into two parts, one part is insensitive permission, when the application is installed, The system directly allows the app to obtain permissions; for some sensitive and dangerous permissions, such as the permission to read and write SMS messages, the system prompts the user whether to allow the app to obtain permissions when the app is in use.

b) Different users of the system have independent and isolated permissions for the same application. The basic insensitive permissions obtained by an application are directly obtained by each user after installation, and some are more sensitive. Permissions are independent. For example: when user 0 opens WeChat, if the permission to read and write SMS is obtained, when switching to user 10, the system will still prompt the user whether to allow or not when opening WeChat for the first time. remind. The same is true for other users.

For user rights management, when an application is installed by a user, insensitive rights will be allowed directly, and sensitive rights must be obtained with the user's permission; under different users, the rights configuration of the same application is independent and isolated from each other, and when the user switches When the application is used for the first time, the user needs to be prompted whether to authorize the sensitive permissions.

In one embodiment, the process of implementing the multi-open application set based on the multi-user mechanism can be described as follows:

Assuming that the default user of the smart terminal is the main user, the user saves the installation package (package, APK) file of the application ABC, such as ABC.apk, into the smart terminal by downloading from the application store or copying it from other sources under the main user. After installing ABC.apk under the main user, an icon of the main application ABC will be generated on the desktop of the main user. When the avatar creation request for the main application ABC is detected under the master user, a slave user can be created in the slave user (if there is no slave user currently, the creation process is completed without the user's awareness, or Install ABC.apk under the user's account and password without the need to set up the avatar application. In order to distinguish the main application from the avatar application, you can add an identifier (assuming *) to the newly installed avatar application, and the avatar application can be recorded as ABC* . When ABC* is successfully installed, you can specify to send a notification of "installation successful" (with the mark * added to the notification) to the main user. After receiving the notification, the desktop under the main user will generate an icon with the mark * , to distinguish it from the icon of the main application ABC, which can be used as the access port for operating the avatar application in the main user. When the icon is clicked, the system will specify ABC* to start under the slave user, and the corresponding ABC* Relevant processes are also running under the slave user, and the human-computer interaction interface (referred to as the interface) of ABC* is displayed under the master user. At this time, the interface of ABC* can also be used as the access port for operating the clone application in the master user.

For a clone application, its access port in the primary user may have various forms, which are not specifically limited in this embodiment. For example, it may be a desktop icon containing an application identifier, which is used to identify the current The avatar application is distinguished from the main application and other avatar applications; it can also be an application logo attached to the main application icon; it can also be an icon containing the application logo in the form of a floating window; it can also exist in the notification center and other locations s project.

The intelligent terminal user can operate the main application in the main user, and can also operate the corresponding avatar application through the access port in the main user. It can be understood that the same main application can correspond to multiple sub-applications, and each sub-application is installed in a different slave user, so that each sub-application runs in different sub-users, and they are different from each other during the running process. interference.

The advantage of implementing multiple applications based on the multi-user mechanism is that, compared with third-party multiple-open assistant software, it is more secure to avoid third-party software from pushing advertisements and stealing user privacy data, etc.; For the solution in which the main body and the application avatar both run under the same user, it reduces the process interference between different application avatars or application main bodies under the same user, and avoids the occurrence of functional loss caused by the complex operating environment.

Step 230 , according to the preset priorities of the cache file subdirectory, the spam message subdirectory and the spam subdirectory, delete the target data in the subdirectories in descending order of priority.

In this embodiment, the target data of the target application and the associated application are respectively stored in preset file directories under their respective storage paths, wherein the preset file directories may include a cache file subdirectory, a spam message subdirectory, and a spam subdirectory, The cache file subdirectory is used to store cached data, the spam message subdirectory is used to store spam text messages, and the spam subdirectory is used to store spam emails.

When the system storage space is insufficient, the target data can be deleted. Exemplarily, the priority of each of the above subdirectories can be set, and the data in the subdirectory with higher priority can be deleted first. For example, the cache file subdirectory can include video files, audio files and picture files. The priority can be set according to the size of the file. For example, the video file has the highest priority and the picture file has the lowest priority. When deleting the data in the cache file subdirectory first, Delete the data in the video file first. In this embodiment, the priority of the subdirectory can also be set according to the frequency of data usage, and the highest priority is set for the subdirectory corresponding to the data whose usage frequency is 0 (eg, spam short message or spam).

Step 240: After deleting the target data in any subdirectory, ask whether to continue to delete the target data.

On the basis of the above technical solution, each time the target data in a subdirectory is deleted, the mobile terminal will ask the user whether to continue to delete the target data, and the user can choose Yes or No according to the size of the remaining storage space. Continue to delete the target data in the next subdirectory in descending priority order. Therefore, if the remaining space of the mobile terminal is sufficient, some data that the user wants or thinks are still available can be reserved.

In the data deletion method for multi-open applications provided by the embodiment of the present invention, by setting priorities for subdirectories storing target data, when the target data is deleted, the target data in the subdirectories are deleted in descending order of priority of the subdirectories , the junk data that occupies the largest storage space or the usage frequency is 0 can be preferentially deleted, and at the same time, when the remaining space of the mobile terminal is sufficient, some data that the user wants or thinks are still available can be retained.
