detailed description

The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here 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, only parts related to the present invention are shown in the drawings but not all content.

Fig. 1 is a flowchart of a multi-open application data operation method provided by an embodiment of the present invention. This embodiment is applicable to the situation where one application in a multi-open application set operates on data of other associated applications. The method can be executed by a data operation device with multiple applications, the device can be realized by software and/or hardware, and the device can be configured in a mobile terminal such as a mobile phone or a tablet computer. The method specifically includes the following steps:

Step 110 , in the current application, monitor data operation instructions and target application selection instructions for the target application.

Wherein, the current application and the target application are different applications in a multi-open application set, and the multi-open application set includes a main application and all clone applications corresponding to the main application. There are many ways to implement the multi-open application set, which are not specifically limited in this embodiment. For example, different versions of applications can be installed separately, and one version can be used as the main application, and other versions can be used as secondary applications. Among them, the installation package (APK) file of the application can be modified by decompiling, and then the modified APK file can be installed. Install different versions of the same application; as another example, it can be realized by applying third-party multi-opening assistant software that simulates user space and dynamic loading technology; as another example, it can be realized by modifying the system mechanism.

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

The multi-opening application refers to an application program that performs multiple application opening (that is, one application program is divided into two or more, so that different accounts can be logged in).

Wherein, the current application refers to a currently displayed application program. The data operation instruction and the target application selection instruction may be initiated by the user actively, or may be automatically initiated according to the change of the data of the current application. The data operation instruction indicates an object to be operated and a specific operation manner, and the target application selection instruction indicates an identification of a target application. The data manipulation instructions preferably include data modification instructions and/or data deletion instructions.

In the currently displayed application program, the data operation instruction and target application selection instruction of the target application associated with the current application can be monitored, so that the data of the target application can be correspondingly processed according to the data operation instruction and target application selection instruction in the current application. operate.

Step 120, access the data of the target application according to the target application selection instruction.

According to the target application selection instruction, the data storage path of the target application is acquired, so as to access the data of the target application according to the data storage path of the target application. Wherein, the data storage path of the target application may be related to the identifier of the target application, so that the data storage path of the target application can be acquired according to the identifier of the target application.

Among them, the main application and the clone application in the multi-open application collection can be distinguished by different application identifiers, that is, a symbol can be added on the basis of the application identifier of the main application to indicate the identifier of the clone application. For example, the identifier of the WeChat main application is For weixin, the first clone application is identified as weixin1 or weixin*, and the second clone application is identified as weixin2 or weixin**, so that the main application and each clone application can be clearly distinguished.

Step 130: Operate the data of the target application according to the data operation instruction.

According to the data operation instruction, the data to be operated in the data of the target application is found, and the data to be operated is operated in a corresponding manner (such as modification or deletion, etc.).

In the technical solution of this embodiment, by listening to the data operation instruction and the target application selection instruction for the target application in the current application, the data of the target application is operated according to the data operation instruction and the target application selection instruction in the current application without having to After switching to the display interface of the target application, the data of the target application can be operated, which simplifies the data operation process of opening multiple applications.

FIG. 2 is a flow chart of another data operation method for multiple applications provided by the embodiment of the present invention. This embodiment is optimized on the basis of the above embodiments, and further adds an independent data storage path for the clone application. The method specifically includes the following steps:

Step 210, after creating the clone application, create an independent data storage path for the clone application.

Wherein, the clone application refers to the clone application corresponding to the main application in the multi-open application set.

Generally, the avatar application is installed in a user space different from that of the main application. After the avatar application is created, an independent data storage path is created for the avatar application, so that the data of the avatar application can be operated more conveniently.

Wherein, after creating the clone application, creating an independent data storage path for the clone application preferably includes:

After the clone application is created, an independent data storage path is created for the clone application according to the user space identifier of the clone application.

After the clone application is created, an independent data storage path can be created for the clone application according to the user space identifier of the clone application, so that the data storage location of the clone application can be accurately distinguished.

For example: when creating the first avatar application, you can create a slave user space through the multi-user service (UserManagerServcie) of the application avatar management module, automatically assign the user space identifier userId to u10 for the slave user space, and create a data storage path for it data/user/u10, assuming that the avatar application is WeChat, the data storage path created by the application avatar management module for the avatar application is data/user/u10/weixin, which is used to save the operation data of the avatar application at runtime.

Step 220, monitor the data operation instruction and target application selection instruction to the target application in the current application.

Wherein, the current application and the target application are different applications in a multi-open application set, and the multi-open application set includes a main application and all clone applications corresponding to the main application.

Wherein, the multi-open application set is implemented based on a multi-user mechanism. Specifically, the implementation of the multi-application set based on the multi-user mechanism may include the following content: the main application is installed in the main user space, the avatar application is installed in the secondary user space, and the main user space contains the interface for operating the avatar application. Entrance.

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

1. Multi-user management

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

b) Users who use the slave user space, such as ordinary users (non-master users) and guest users, can be collectively referred to as slave users;

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

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

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

For multi-user management, the slave user space can be managed through the master user space, including the creation, deletion and permission setting of the slave user space. When switching between, reload a series of interfaces such as the desktop corresponding to the user space.

2. Multi-user installation and uninstallation of applications

a) Applications installed by default will be installed in all created user spaces, and application icons will be visible on the desktops of other user spaces;

b) Applications installed through file management in the main user space will not be installed in other user spaces, and application icons will not be visible on the desktops of other user spaces;

c) The system can specify a userid (user space identifier) when installing or uninstalling an application, and the specified application is installed in a specified user space, or the application is uninstalled in a specified user space. It is also possible to install the application for all user spaces, or uninstall the application.

d) Application B is uninstalled in user space A. For other user spaces, application B still exists, and application icons can be seen on the desktop. In other user spaces, application B can be used normally.

For multi-user installation and uninstallation of applications, the default installed applications will be installed to all created user spaces (including the main user space and secondary user space), and application icons will be generated on the desktops of each user space; and in the main user space through The application installed by file management is only installed in the main user space, and the application icon is generated on the desktop of the main user space, and is not installed in the secondary user space; the installation/uninstallation of the application can also be based on the designation of the user space by the user. Specify the user space ID, and the installation/uninstallation of specified applications in the main user space and secondary user space is carried out in a certain user space, some user spaces, or all user spaces; the uninstallation of the same application is carried out independently in each user space, for Uninstalling an application in a certain user space does not affect the use of the application in other user spaces.

3. User data management

a) User id directory related to system data: stores various system data storage corresponding to user space, for example: 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 in the user space. If the application operation generates data, the application data is also stored in this directory.

c) System SD card (Secure Digital Memory Card, secure digital card) directory: the SD card directory that the user sees in each user space is different, and only the SD card directory of the current user space can be seen.

For user data management, under the multi-user implementation mechanism, system data and application-related data in each user space are stored in different data storage paths, for example, various system data in a user space are stored in the designated first data storage path, while the installed application package directory and application data generated by application operations are stored in the specified second data storage path; the data storage in each user space is independent of each other, and users can only view the current Stored data in user space, such as the SD card directory of the current user space.

4. User rights management

a) After the application is installed, the various permissions applied for by the application (for example: permission to read storage directory, permission to read and write text messages, permission to open camera, etc.) will be divided into two parts, one part is not sensitive permission, when the application is installed, The system directly allows applications to obtain permissions; for some sensitive and dangerous permissions, such as the permission to read and write text messages, the system will prompt the user whether to allow the application to obtain permissions when the application is in use.

b) The system is in different user spaces, and the permissions for the same application are independent and isolated. The basic insensitive permissions obtained by an application are directly obtained in each user space after installation, while some are more sensitive. The dangerous permissions are independent. For example: when you open WeChat in user space 0, if you have obtained the permission to read and write SMS, when you switch to user space 10, the system will still prompt the user whether to allow it when you open WeChat for the first time, and it will not be because WeChat is in user space 0. Permissions without reminder. The same is true for other user spaces.

For user permission management, when an application is installed in a user space, insensitive permissions will be directly allowed, and sensitive permissions must be obtained with the user's permission; in different user spaces, the permission configurations for the same application are independent and isolated from each other. When switching between user spaces, the user needs to be prompted whether to authorize the sensitive permissions of the application used for the first time.

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

Assuming that the default user space of the smart terminal is the main user space, 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 from other sources under the main user space In , after the system installs ABC.apk in the main user space, an icon of the main application ABC will be generated on the desktop of the main user space. When an avatar creation request for the master application ABC is detected in the master user space, a slave user space can be created in the slave user space (if there is no slave user space currently, the creation process is under the condition that the user cannot perceive Completed, and there is no need for the user to set an account and password) to install ABC.apk to get the avatar application. In order to distinguish the main application from the avatar application, an identifier (assumed to be *) can be added to the newly installed avatar application, and the avatar application can be used by Denote it as ABC*. When ABC* is successfully installed, you can specify to send the notification of "successful installation" (add the logo * to the notification) to the main user space. After receiving the notification, the desktop under the main user space will generate a message with the logo * icon to distinguish it from the icon of the main application ABC. This icon can be used as the access port for operating the avatar application in the main user space. When the icon is clicked, the system will designate ABC* to start in the secondary user space, and The related processes corresponding to ABC* are also running in the secondary user space, and the human-computer interaction interface (referred to as the interface) of ABC* is displayed in the main user space. At this time, the ABC* interface can also be used as the clone application in the main user space The entry point for operations.

For the avatar application, its access port in the main user space may exist in various forms, which are not specifically limited in this embodiment, for example, it may be a desktop icon containing an application identifier, and the application identifier is used to The current clone application is distinguished from the main application and other clone 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, etc. position item.

The mobile terminal user can operate the main application in the main user space, and can also operate the corresponding avatar application through the access port in the main user space. It can be understood that the same main application can correspond to multiple avatar applications, and each avatar application is installed in a different slave user space, so that each avatar application runs in a different slave user space. Do not interfere with each other.

The advantage of implementing multi-opening applications based on the multi-user mechanism is that, compared with third-party multi-opening assistant software, it avoids behaviors such as pushing advertisements and stealing user privacy data by third-party software, and has higher security; For the solution that both the application and the clone application run in the same user space, the process interference between different clone applications or the main application in the same user space is reduced, and the occurrence of function loss caused by the complex operating environment is avoided.

Exemplarily, in this embodiment, the main application and the clone application can be distinguished by the user space identifier userid and the application identifier Uid.

Step 230, access the data of the target application according to the target application selection instruction.

Step 240: Operate the data of the target application according to the data operation instruction.

In the technical solution of this embodiment, on the basis of the above embodiments, by creating an independent data storage path for the clone application after creating the clone application, it is convenient to open the main application or each clone application in multiple applications data to operate.

This embodiment is optimized on the basis of the above embodiment, and the target application selection instruction preferably includes the target application application identification and user space identification, and further optimize "according to the target application selection instruction, access the data of the target application" to "according to the application identification and user space identification of the target application, determine the data of the target application storage path; according to the data storage path of the target application, access the data of the target application". The method specifically includes the following steps:

Step 310 , in the current application, monitor data operation instructions and target application selection instructions for the target application.

Wherein, the current application and the target application are different applications in a multi-open application set, and the multi-open application set includes a main application and all clone applications corresponding to the main application.

Step 320: Determine the data storage path of the target application according to the application identifier and the user space identifier of the target application.

The data storage path of the target application is related to the application identifier and the user space identifier of the target application, and the data storage path of the target application can be clearly determined according to the application identifier and the user space identifier of the target application. For example, if the target application is WeChat, the user space ID is u10, and the application ID is weixin, then the data storage path of the target application can be determined as data/user/u10/weixin.

Step 330, access the data of the target application according to the data storage path of the target application.

Find the storage location of the data of the target application according to the data storage path of the target application, so as to access the data of the target application.

Step 340: Operate the data of the target application according to the data operation instruction.

The technical solution of this embodiment, on the basis of the above embodiments, can clearly determine the data storage path of the target application through the application identifier and user space identifier of the target application, so that the data of the target application can be accessed conveniently.
