android - Releasing PendingIntent after reentering app -

anyone knows how cancel pendingintent after leaving app button? when pendingintent switched on , canceled on 1 session without exiting app in between it's fine - got covered, when leave , reenter can't anymore cancel , have wait alarm.

mainactivity:

b5.setonclicklistener(new view.onclicklistener() {             @override             public void onclick(view v) {                 setcall(12000);                 pendingintent.cancel();                 if (alarmmanager!= null) {                     alarmmanager.cancel(pendingintent);                 }             }         });  public void setcall(int timetocall){     if (alarmmanager!= null) {         alarmmanager.cancel(pendingintent);     }     string name = e1.geteditabletext().tostring();     //toast.maketext(getapplicationcontext(), name, toast.length_short).show();     intent intent = new intent(mainactivity.this, thisbroadcastreceiver.class);     intent.setflags(intent.flag_include_stopped_packages);     intent.putextra("name",name);     pendingintent = pendingintent.getbroadcast(getapplicationcontext(), 0, intent, pendingintent.flag_update_current);      alarmmanager = (alarmmanager) getsystemservice(context.alarm_service);     alarmmanager.set(alarmmanager.elapsed_realtime_wakeup,             systemclock.elapsedrealtime() + timetocall, pendingintent); } 

broadcastreceiver:

@override public void onreceive(context context, intent intent) {     string name = intent.getextras().getstring("name");      intent = new intent(context, callscreen.class);     i.setclassname("(package)", "(classname)");     i.setflags(intent.flag_activity_new_task);     i.putextra("name2", name);     context.startactivity(i);     toast.maketext(context, name, toast.length_short).show(); } 

if want cancel pendingintent after activity destroyed (actually after losing reference original pendingintent object), need recreate object in same way , cancel it.

therefore, create object of pendingintent before trying cancel it. also, call cancel directly on pendingintent object.
