android - Alarm manager Not triggering with correct time -

i know common thread in didn't find answer question . want trigger dynamic broadcast receiver @ particular time. using below code

public void method1() {     br = new broadcastreceiver() {         @override         public void onreceive(context c, intent i) {             dotask();         }     };     registerreceiver(br, new intentfilter("com.xxxx.wakeup"));     pi = pendingintent.getbroadcast(this, 0,             new intent("com.xxxx.wakeup"), 0);     = (alarmmanager) (this.getsystemservice(context.alarm_service));      setalarmmanagerobject(); } 

and setalarmmanagerobject() method here

   public void setalarmmanagerobject() {     calendar cal = calendar.getinstance();     int year = cal.get(calendar.year);     int month = cal.get(calendar.month);     int day = cal.get(calendar.day_of_month);     cal.set(year, month, day             , com.xxxx.constants.alarmhour             , com.xxxx.constants.alarmminute             , com.xxxx.alarmsecond);      am.setrepeating(alarmmanager.elapsed_realtime, cal.gettimeinmillis(),             alarmmanager.interval_day, pi); } 

my problem when used alarmmanager.rtc_wakeup wake when device off. don't want property in app. used alarmmanager.elapsed_realtime, elapsed_realtime alarm manager not triggering. want alarm manager trigger exact @ same time. if device off or sleep condition alarm manager off after device wake up.it should trigger @ exact time. appreciated.

you need use this:-

 alarmmanager.set(alarmmanager.elapsed_realtime_wakeup (or alarmmanager.elapsed_realtime),   systemclock.elapsedrealtime() + constants.delay_in_millis,   pendingintent); 

you can calculate delay_in_millis time delay in milliseconds current system time.

for repeating alarm can have code this:-

 alarmmanager.setrepeating(alarmmanager.elapsed_realtime_wakeup,  systemclock.elapsedrealtime() + constants.delay_in_millis,   constants.one_day_in_millis,   pendingintent);
