Abstract

The present invention discloses an application data synchronization method and an apparatus. When a first operating system and a second operating system are installed in a terminal, and a first application and a second application that have a same function are installed on the first operating system and the second operating system respectively, the method includes: when the second application runs on the second operating system, performing the function by using second application data, and updating the second application data, where the second application data is updated according to first application data, and the first application data is updated when the first application runs on the first operating system to perform the function; where the first application data and the second application data are stored in the terminal. By using the solutions, sharing of data of a same application between different systems is more convenient and less time-consuming.

Claims

1. An application data synchronization method, wherein the method is applied to a terminal, a first operating system and a second operating system are installed in the terminal, a first application is installed on the first operating system, a second application is installed on the second operating system, and at least one same function is achieved by the first application and the second application, wherein the method comprises:

when the second application runs on the second operating system, performing the function by using second application data, and updating the second application data, wherein the second application data is updated according to first application data, and the first application data is updated when the first application runs on the first operating system to perform the function, wherein

the first application data and the second application data are stored in the terminal.

2. The method according to claim 1, wherein the first application data is stored in a first file of the terminal, and the second application data is stored in a second file of the terminal, wherein the first file and the second file are different files.

3. The method according to claim 2, wherein a process of updating the second application data according to the first application data comprises at least one of the following:

when the second operating system is started, using, according to a storage location of the first file and a storage location of the second file, the first application data stored in the first file to update the second application data stored in the second file when it is determined that an update time of the first file is later than an update time of the second file;

or

when the first application data is updated, using, according to a storage location of the first file and a storage location of the second file, updated first application data stored in the first file to update the second application data stored in the second file.

4. The method according to claim 1, wherein the first application data and the second application data are stored in a data sharing file of the terminal.

5. The method according to claim 4, wherein a process of updating the second application data according to the first application data comprises:

when the first application data is updated, storing updated first application data in the data sharing file; and

generating the second application data after mapping the data sharing file to the second operating system.

6. A terminal, wherein a first operating system and a second operating system are installed in the terminal, a first application is installed on the first operating system, a second application is installed on the second operating system, and at least one same function is achieved by the first application and the second application, wherein the terminal comprises:

an update module, configured to;

when the second application runs on the second operating system, perform the function by using second application data, and update the second application data, wherein the second application data is updated according to first application data, and the first application data is updated when the first application runs on the first operating system to perform the function; and

a storage module, disposed in the terminal and configured to store the first application data and the second application data.

7. The terminal according to claim 6, wherein the storage module is further configured to store the first application data in a first file, and store the second application data in a second file, wherein the first file and the second file are different files.

8. The terminal according to claim 7, wherein the update module is further configured to:

when the second operating system is started, if it is determined that an update time of the first file is later than an update time of the second file, use, according to a storage location of the first file and a storage location of the second file, the first application data stored in the first file to update the second application data stored in the second file;

or

when the first application data is updated, use, according to a storage location of the first file and a storage location of the second file, updated first application data stored in the first file to update the second application data stored in the second file.

9. The terminal according to claim 6, wherein the storage module is configured to store the first application data and the second application data in a data sharing file.

10. The terminal according to claim 9, wherein the update module is further configured to:

when the first application data is updated, store updated first application data in the data sharing file; and

generate the second application data after mapping the data sharing file to the second operating system.

11. A terminal, comprising:

a first operating system and a second operating system installed in the terminal;

memory configured to store system data corresponding to the first operating system and system data corresponding to the second operating system are stored in the memory, wherein a first application is installed on the first operating system, a second application is installed on the second operating system, and at least one same function is achieved by the first application and the second application;

a processor configured to call the system data to correspondingly run the first operating system or the second operating system, and further configured to;

when the second application runs on the second operating system, perform the function by using second application data, and update the second application data, wherein the second application data is updated according to first application data, and the first application data is updated when the first application runs on the first operating system to perform the function; and

wherein the memory is further configured to store the first application data and the second application data.

12. The terminal according to claim 11, wherein the memory is further configured to store the first application data in a first file, and store the second application data in a second file, wherein the first file and the second file are different files.

13. The terminal according to claim 12, wherein the processor is further configured to:

when the second operating system is started, if it is determined that an update time of the first file is later than an update time of the second file, use, according to a storage location of the first file and a storage location of the second file, the first application data stored in the first file to update the second application data stored in the second file;

or when the first application data is updated, use, according to a storage location of the first file and a storage location of the second file, updated first application data stored in the first file to update the second application data stored in the second file.

14. The terminal according to claim 11, wherein the memory is further configured to store the first application data and the second application data in a data sharing file.
