Operating status after variation is front stage operation or running background.In one embodiment, mobile terminal can be at regular intervals
All process lists being currently running are obtained by the RunningAppProcessInfo class of active manager, for example, every 5
Second obtains all process lists being once currently running, and judges each state of a process being currently running in process list one by one
It is front stage operation or running background.This operating status of process can be compared with last operating status, if into
The operating status of journey last time is different from this operating status, then can determine that front and back state change occurs for the process, mobile
Terminal can determine this operating status of the process.
Step 320, if the operating status after variation is front stage operation, process is assigned to first resource group.
If the operating status after process variation is front stage operation, it can illustrate that the process is switched to foreground from running background and transports
Process can be assigned to first resource group by row, mobile terminal.Optionally, mobile terminal can divide different resource groups in advance, no
