android - snooze not working for alarm manager - 


snoozebtn.setonclicklistener(new onclicklistener() {          @override         public void onclick(view v) {              intent myintent = new intent(getapplicationcontext(), alarmalertbroadcastreciever.class);             myintent.putextra("alarm", this);              pendingintent pendingintent = pendingintent.getbroadcast(getapplicationcontext(), 0, myintent,pendingintent.flag_cancel_current);              alarmmanager alarmmanager = (alarmmanager)getapplicationcontext().getsystemservice(context.alarm_service);              alarmmanager.set(alarmmanager.rtc_wakeup, getalarmtime().gettimeinmillis(), pendingintent);               toast.maketext(getapplicationcontext(), "snoozed 10 mins", toast.length_long);             finish();         }      });

when click snooze button, alarm must restart after 10 mins , not working.

} }

this alarm activity

it easy snooze alarm set the alarm same id not need cancel previous alarm following example.

pendingintent pendingintent = pendingintent.getbroadcast(getapplicationcontext(), sameid, myintent,pendingintent.flag_cancel_current);  alarmmanager alarmmanager = (alarmmanager) getsystemservice(alarm_service);      alarmmanager.set(alarmmanager.rtc_wakeup, gettimeaftertenminute,pendingintent );

please edit sameid variable in sample code same number given @ time of setting alarm.this cancel alarm , set new one.

as logcat suggest there must object trying access null inside oncreate method of alarmalertactivity.

please paste alarmalertactivity oncreate method.

hope :).
