Adopting the technical solution of the present invention, when the mobile terminal refreshes the version and reinstalls the core application program, it detects whether there is a folder corresponding to the application program in the core partition, and if it exists, it uses the core data in it, otherwise it creates a new folder and creates new link relationship.

According to the technical solution of the present invention, the core data is separated from other data, the independence of the core data is ensured, the core data can be updated in real time, and the core data of the user can be protected when the terminal has a problem, and the core data can be guaranteed to be up-to-date of.

Fig. 3 shows a flow chart of a data saving method based on an Android system according to an embodiment of the present invention.

As shown in FIG. 3 , in step 302 , a new core partition is created to store user's core data, and the core data is data generated when running a preset core application program.

At step 304, the application is installed.

In step 306, it is determined whether the currently installed application program is a core application program, if the determination result is no, then enter step 308, and install the application program according to the related technology; if the determination result is yes, then enter step 310.

In step 310, check whether there is a directory corresponding to the core application program currently installed in the newly-built core partition (that is, whether there is a folder-the second folder with core data corresponding to the core application program), if there is no corresponding directory , then go to step 312, create a directory in the core partition, and the folder corresponding to the directory is used to store the data of the core application, and then go to step 314; if there is a corresponding directory, go to step 314.

In step 314, a folder corresponding to the core application program (namely the first folder) is created under the data partition (/data/data/).

In step 316, create a link (such as a symbolic link, which contains a text string and is interpreted by the operating system as a path pointing to other files or directories) through a command, and link the first folder to the corresponding directory under the core partition. Take the folder (the first folder) under the data partition directory as the source folder, and the folder to be linked (the second folder under the core partition) as the target folder.

For the system, such a design does not change the original architecture. When the core application is running, the system saves the relevant data generated when the core application is running (such as when the contact application is running, create a new contact, and save the newly created contact. For the user, only need to directly perform the save operation, the system will think that the relevant data (core data) is saved in the data partition (data partition), and does not need to modify any other places, but in actual operation, Because the data partition is only a link (equivalent to a shortcut on the computer), the first folder is operated. In fact, the directory corresponding to the core partition is operated, and the corresponding core data is saved to the core partition. .

Through the above method, the user's core data can be directly saved to the newly created core partition, realizing data isolation, because the data partition can be directly operated by the user, while the core partition can only be operated by the system core application program, which increases data security When there is a problem with the data in the data partition, or the system cannot run normally due to some reasons such as installation of an inappropriate installation file, and it is necessary to restore the factory settings or re-refresh the version, you can save the core data. Partitions are treated specially. For example:

When restoring factory settings, you need to confirm to clear the core partition. If there is no additional confirmation, the core partition will not be cleared by default.

Alternatively, add a flag bit for the core partition to set whether the core partition needs to be formatted. When refreshing the version, first check whether the flag is true, if true, format the core partition; otherwise, do not format the core partition, only clear other partitions, so that the user's core data can be saved even if the version is refreshed .

Adopting the technical solution of the present invention, when the mobile terminal refreshes the version and reinstalls the core application program, it detects whether there is a folder corresponding to the application program in the core partition, and if it exists, it uses the core data in it, otherwise it creates a new folder and creates new link relationship.

Therefore, separating the core data from other data ensures the independence of the data, updates the data in real time, protects the user data and ensures that the data is up-to-date when there is a problem with the terminal.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
