<uses-permission android:name="android.permission.KILL_BACKGROUND_PROCESSES" />
http://developer.android.com/reference/android/app/ActivityManager.html#killBackgroundProcesses%28java.lang.String%29

public void killBackgroundProcesses (String packageName)

Since:
API Level 8

Have the system immediately kill all background processes associated with the given package. This is the same as the kernel killing those processes to reclaim memory; the system will take care of restarting these processes in the future as needed.

You must hold the permission

KILL_BACKGROUND_PROCESSES

to be able to call this method.

Parameters

packageName	The name of the package whose processes are to be killed.
