Auto Logout from app after 15 min due to inactivity in android -

i want session management in android application.i want logout user application if inactive or not interacting application. not sure when start service. starting in onresume(). have used countdowntimer automatic logout after 15min. not working. there efficient or working solution session management.

logoutservice:

public class logoutservice extends service {     public static countdowntimer timer;     @override     public void oncreate(){         // todo auto-generated method stub         super.oncreate();         timer = new countdowntimer(5 * 60 * 1000, 1000) {             public void ontick(long millisuntilfinished) {                 //some code                 log.v("logoutservice", "service started");             }              public void onfinish() {                 log.v("logoutservice", "call logout service");                 // code logout                 stopself();             }         };     }     @override     public ibinder onbind(intent intent) {         // todo auto-generated method stub         return null;     } } 

mainactivity:

@override         protected void onstop() {             super.onstop();             logoutservice.timer.cancel();         }      @override         protected void onresume() {             super.onresume();             startservice(new intent(this, logoutservice.class));             logoutservice.timer.start();         } 

first of 1 reason can guess why not working may because of code.

 @override     protected void onstop() {         super.onstop();         logoutservice.timer.cancel();     } 

lets assume if device screen goes of onstop() triggered hence timer cancelled , no further checking.

cancel time on ondestroy this.

 @override     protected void ondestroy() {         super.ondestroy();         logoutservice.timer.cancel();     } 

now since ask there better way of doing can use touch event

and start counter in thread or timer , if counter reaches 15 min close activity calling

 finish() 

here code detect ontouch event of entire activity oncreate()

   setcontentview(r.id.main);    view view = findviewbyid(r.id.main);      view.setontouchlistener(new view.ontouchlistener() {           @override           public boolean ontouch(view view,motionevent event) {                 ntouchcouter = 0; // don't forget reset counter ontouch                return true;                         }              });
