java - BroadcastReceiver onReceive() never invoked -

i trying invoke broadcastreceiver resides inner class. since it's inside class need register receiver programmatically. can see alarm works first time since device exits doze when triggered, can't re-register alarm since onreceive() method never triggers when alarm goes off.

i have tried several combinations , examples found online can't seem work.

my guess need add more intentfilter in order broadcast.

relevant code:

public class analogwatchface extends canvaswatchfaceservice {     private class engine extends canvaswatchfaceservice.engine {         @override         public void oncreate(surfaceholder holder) {             setbufferclearalarm();         }          private void setbufferclearalarm()         {             alarm = new bufferalarmreciever();              intentfilter filter = new intentfilter();             filter.addaction("0");             analogwatchface.this.registerreceiver(alarm, filter);              alarm.setalarm(analogwatchface.this);         }          public class bufferalarmreciever extends broadcastreceiver         {             private alarmmanager alarmmanager;             private pendingintent alarmintent;              @override             public void onreceive(context context, intent intent)             {                 setalarm(context);             }              //sets alarm             public void setalarm(context context) {                 cancelalarm(context);                 alarmmanager = (alarmmanager) context.getsystemservice(context.alarm_service);                  intent intent = new intent(context, bufferalarmreciever.class);                 intent.setaction("0");                 alarmintent = pendingintent.getbroadcast(context, 0, intent, 0);                  log.d(tag, "setting alarm");                  alarmmanager.setalarmclock(new alarmmanager.alarmclockinfo(system.currenttimemillis()+60000,alarmintent),alarmintent);             }              //cancels             public void cancelalarm(context context) {                 alarmmanager = (alarmmanager) context.getsystemservice(context.alarm_service);                 intent intent = new intent(context, bufferalarmreciever.class);                 intent.setaction("0");                 alarmintent = pendingintent.getbroadcast(context, 0, intent, 0);                  log.d(tag, "cancelling alarm");                  alarmmanager.cancel(alarmintent);             }         }     } }
