How the Android implementation closes all activity when it exits _android

This example implements the ability to turn off all activity when Android exits and share them for your reference. The specific methods are as follows:

In general, when Android exits, some activity may not be closed. To turn off all activity when Android exits, here are the following classes:

Class public class
closeactivityclass{public 
 
  static list<activity> activitylist = new for closing an activity Arraylist<activity> ();
 
  public static void Exitclient (context ctx)
  {
   //Close all activity for
   (int i = 0; i < activitylist.size (); i++) c7/>{
     if (null!= activitylist.get (i))
     {
       activitylist.get (i). Finish ();
     }
   Activitymanager activitymgr = (activitymanager) ctx.getsystemservice (context.activity_service);
   Activitymgr.restartpackage (Ctx.getpackagename ());
   System.exit (0);
  }
}

Then add one sentence to the OnCreate (Bundle savedinstancestate) method of each activity in the application:

CloseActivityClass.activityList.add (this);

When the application exits:

Closeactivityclass.exitclient (Mainactivity.this);

This allows all activity of the application to be completely shut down when the application is exited.
