Step 2, clears up the application program not being set to white list in background application or restarts control;
Preferably, further, detect the current memory utilization rate that mobile terminal system runs, judge whether current memory utilization rate is greater than default memory usage value, if so, then enters step 4, if not, then enters step 5;
Step 4, clears up the application program being set to white list or restarts control, and entering application program;
Step 5, the application program being set to white list of having cleared up in reboot step 4, and enter application program.
Preferably, frame rate value is preset by user, comprises smooth grade and fine and smooth grade, and the frame per second of smooth grade is greater than 20 frames/second, and the frame per second of fine and smooth grade is greater than 40 frames/second.
Preferably, step 2, the concrete grammar cleared up the application program not arranging white list in background application or restart control is: each application program of traversal backstage, judge whether each application program is set to the application program of white list successively, if, then retain this program process, if not, then terminate this program process or control is restarted to this application process.
Preferably, memory usage value is preset by user.
Preferably, step 4, according to the priority in white list set by each application program when clearing up the application program being set to white list or restart control, carries out from low to high.
Preferably, in white list, the priority of each application program is preset by user.
Preferably, also comprise, after entering application program, if by full frame for application program operation, then shutdown system desktop special efficacy and the application program multimedia service of not applying.
Beneficial effect of the present invention is: by when starting application program, detect the current frame rate of the current display frame of mobile terminal, and according to the comparative result of this current frame rate and preset frame rate value, cleaning backstage does not arrange the running memory of process with the system of saving of the application program of white list, the current memory utilization rate further run by detection system, and according to the comparative result of this current memory usage and default memory usage value, the process of the application program being provided with white list is cleared up or restarts control, the application program for opening is enable to have enough running memories.
The present invention is under the prerequisite not affecting user operation and experience, the change of system application state is effectively detected, and realize optimization and the user behavior analysis of internal memory further, which simplify current memory management mechanism, effectively prevent the operation such as to manslaughter affecting Consumer's Experience, and system achieves the unitarity of self application and system interface switching according to the analysis of user behavior.Improving the travelling speed of Android system when not changing hardware setting, improving the operating experience of user.
