android - AlarmManager calls the intent service ASAP rather than at the set time -

i have setexact alarm set in app , when reaches point, instead of activating alarm @ specified time, activates asap!

my alarmmanager code

@targetapi(build.version_codes.m) public void setupalarmmanager(long time) {      final intent intentalarm = new intent(this, alarmservice.class);     final pendingintent pendingintent = pendingintent.getservice(this, 100, intentalarm, pendingintent.flag_one_shot);     final alarmmanager alarmmanager = (alarmmanager) getsystemservice(context.alarm_service);      alarmmanager.setexact(alarmmanager.rtc_wakeup, time, pendingintent);     final handler handler = new handler();     handler.postdelayed(new runnable() {         @override         public void run() {             alarmmanager.cancel(pendingintent);         }     }, 1000);     log.i(tag, "setupalarmmanager: " + time); } 

the handler see if can cancel intent through activity (which doesn't appear working)

my alarmservice

public class alarmservice extends intentservice {  private static final string tag = "tag";  // private ringtone ringtonealarm;  public alarmservice() {     super("alarmservice"); //     ringtonealarm = null;     log.i(tag, "alarmservice: "); }  @override protected void onhandleintent(intent intent) {     log.i(tag, "onhandleintent: ");     uri alarmtone = ringtonemanager.getdefaulturi(ringtonemanager.type_alarm);     ringtone ringtonealarm = ringtonemanager.getringtone(getapplicationcontext(), alarmtone);     ringtonealarm.play(); }  @override public void ondestroy() {     log.i(tag, "ondestroy: ");     super.ondestroy(); //    ringtonealarm.stop(); }   } 

can me figure out why alarmmanager calling intent right away instead of @ set time? intent service plays alarm when alarm activates.

also should using intentservice or broadcastreceiver?

to set alarm 32 seconds now, this:

private void setalarmtofuthure(long time){         calendar cal_alarm = calendar.getinstance();         cal_alarm.add(calendar.second, (int)time); // here add desired value current time (for example: 32 seconds)          final intent intentalarm = new intent(this, alarmservice.class);         final pendingintent pendingintent = pendingintent.getservice(this, 100, intentalarm, pendingintent.flag_one_shot);         final alarmmanager alarmmanager = (alarmmanager) getsystemservice(context.alarm_service);         alarmmanager.setexact(alarmmanager.rtc_wakeup, cal_alarm.gettimeinmillis(), pendingintent);     }
