detecting the upgrade installation package and recording the package name of the upgrade installation package in the system properties when it is determined that the application corresponding to the upgrade installation package is a system application.

5. The method of claim 4 , wherein the detecting the upgrade installation package and recording the package name of the upgrade installation package in the system properties when it is determined that the application corresponding to the upgrade installation package is a system application comprises:

detecting the upgrade installation package, obtaining the name of the upgrade installation package, reading an identification of the application corresponding to the upgrade installation package, and when the identification corresponds to a system application, determining that the application corresponding to the upgrade installation package is a system application, and recording the obtained package name of the upgrade installation package in the system properties.

6. The method of claim 2 , wherein before replacing the original library file with the upgraded library file, the method further comprises:

judging whether the upgraded library file is consistent with the original upgrade installation package stored in the system partition, and if so, then terminating upgrading of the library file; otherwise, replacing the original library file with the upgraded library file.

7. A terminal, comprising a memory and one or more processors, wherein the memory has one or more computer readable program codes stored therein, and the one or more processors are configured to perform the one or more computer readable program codes to implement:

when it is determined that the package name of an upgrade installation package is recorded in system properties, to search a user partition by the package name of the upgrade installation package for an upgraded library file corresponding to the upgrade installation package, wherein the package name of the upgrade installation package is recorded in the system properties when it is determined that an application corresponding to the upgrade installation package is a system application;

to replace an original library file stored in a system partition with the upgraded library file found in the user partition; and

to delete the package name of the upgrade installation package recorded in the system properties.

8. The terminal of claim 7 , wherein the one or more processors are further configured to perform the one or more computer readable program codes to implement:

to inquire an application upgrade server periodically, wherein there is a network connection established between the terminal and the application upgrade server; and

to download the upgrade installation package when the upgrade installation package is found, wherein the upgrade installation package is an installation package corresponding to a new version of the application in the application upgrade server.

9. The terminal of claim 8 , wherein the one or more processors are further configured to perform the one or more computer readable program codes:

to invoke a system service program interface to install the upgrade installation package, wherein the upgraded library file corresponding to the upgrade installation package is stored in the user partition; and

to detect the upgrade installation package and to record the package name of the upgrade installation package in the system properties when it is determined that the application corresponding to the upgrade installation package is a system application.

10. The terminal of claim 9 , wherein the detecting the upgrade installation package and recording the package name of the upgrade installation package in the system properties when it is determined that the application corresponding to the upgrade installation package is a system application comprises:

detecting the upgrade installation package, obtaining the name of the upgrade installation package, reading an identification of the application corresponding to the upgrade installation package, and when the identification corresponds to a system application, determining that the application corresponding to the upgrade installation package is a system application, and recording the obtained package name of the upgrade installation package in the system properties.

11. The terminal of claim 7 , wherein the one or more processors are further configured to perform the one or more computer readable program codes to implement:

to judge whether the upgraded library file is consistent with the original upgrade installation package stored in the system partition, and if so, to terminate upgrading of the library file; otherwise, to replace the original library file with the upgraded library file and to load the upgraded library file.
