Android system off app

1. Overview:There are five priorities for application deployment to a mobile phone: foreground process, visual process, service process, background process, empty process. Android, by default, will not kill the process, the purpose of this practice is: to open the application again when you can quickly start, save time. But this also brings a problem, there are many applications in the background to leave an empty process, which will occupy some memory space, affecting the speed of the phone. as a responsible programmer, we want to make sure that the application releases the corresponding process at the end.
2. Closing modeFirst: Get the ID of the current process first, and then kill the thread.

  Gets the ID of the current process     int pid = Android.os.Process.myPid ();     This method can only be used for suicide operation     Android.os.Process.killProcess (PID);

The second type: terminates the currently running Java Virtual machine, causing the program to stop.

<span style= "White-space:pre" ></span>system.exit (0);

The third type: forces all executions that are associated with the package to be closed.

Activitymanager am = (activitymanager) getsystemservice (activity_service);     Am.killbackgroundprocesses (Getpackagename ());

The third need to add permissions:

<uses-permission android:name= "Android.permission.KILL_BACKGROUND_PROCESSES"/>
