Backup method of application program in communication terminal and communication terminal
InactiveCN102508736AShorten the timeSave communication trafficRedundant operation error correctionTraffic capacityContinuous use
The invention is applicable to the technical field of communication and provides a backup method of an application program in a communication terminal and the communication terminal. The backup method comprises the following steps of: detecting the current residual memory space of the communication terminal before downloading a new application program; obtaining the memory occupation value of the new application program; judging whether the current residual memory space is more than the memory occupation value of the new application program; if so, executing an application downloading step; otherwise, executing an application backup step; backing up at least one application program in the communication terminal into a server, automatically deleting the backup application programs in the communication terminal, and returning back to a memory judging step; and downloading the new application program to the communication terminal. Therefore, the problem that the installation is abandoned due to insufficient memory during or after the process of downloading the application program can be avoided, so that the time and communication flow of a user are effectively saved; and meanwhile, the user can selectively back up the application programs which are not usually used into the server, so as to facilitate the continuous use after the application programs are recovered.
