Android Alarm Manager : OnRecive and PendingIntent Service does not get called

Question

I try to use alarm manager to send an intent at 8:30 but the alarm manager never send an intent to the receiver around 8:30.

I there is something messed up in the setAlarm() method but I could not figure it out. Also many posts here also mentioned the service/receiver might be declared wrong in the manifest file, but I am not sure how to properly include receiver and service in the manifest. I have tried to incorporate the package name but it still does not work.

public class EventAlarmReceiver extends WakefulBroadcastReceiver {
private AlarmManager alarmMgr;
private PendingIntent alarmIntent;
private PendingIntent alarmIntent1;

@Override
public void onReceive(Context context, Intent intent) {
    Intent service = new Intent(context, EventSchedulingService.class);
    startWakefulService(context, service);
}

public void setAlarm(Context context) {
        alarmMgr = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
        Intent intent = new Intent(context, EventSchedulingService.class);
        intent.putExtra("silent", true);
        alarmIntent = PendingIntent.getBroadcast(context, 0, intent, 0);

        Calendar calendar = Calendar.getInstance();
        calendar.setTimeInMillis(System.currentTimeMillis());
        // Set the alarm's trigger time to 8:30 a.m.
        calendar.set(Calendar.HOUR_OF_DAY,8);
        calendar.set(Calendar.MINUTE, 30);
        System.out.println(calendar.getTimeInMillis());
        alarmMgr.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), alarmIntent);
}
}

Here is my service file

package edu.ssui.smartsilent;

public class EventSchedulingService extends IntentService {

public EventSchedulingService() {
    super("EventSchedulingService");
}
@Override
protected void onHandleIntent(Intent intent) {
    Log.d("SService", "m1");
    AudioManager mgr = (AudioManager) getSystemService(Context.AUDIO_SERVICE); 
    if(intent.getExtras().getBoolean("silent")==true){
     mgr.setStreamVolume(AudioManager.STREAM_RING, 0, AudioManager.FLAG_REMOVE_SOUND_AND_VIBRATE);
     mgr.setStreamVolume(AudioManager.STREAM_ALARM, 0, AudioManager.FLAG_REMOVE_SOUND_AND_VIBRATE);
     mgr.setStreamVolume(AudioManager.STREAM_SYSTEM, 0, AudioManager.FLAG_REMOVE_SOUND_AND_VIBRATE);
     mgr.setStreamVolume(AudioManager.STREAM_NOTIFICATION, 0, AudioManager.FLAG_REMOVE_SOUND_AND_VIBRATE);
    }
    else
    {
         mgr.setStreamVolume(AudioManager.STREAM_RING, (int) (mgr.getStreamMaxVolume(AudioManager.STREAM_RING)*0.8), AudioManager.FLAG_REMOVE_SOUND_AND_VIBRATE);
         mgr.setStreamVolume(AudioManager.STREAM_ALARM, (int) (mgr.getStreamMaxVolume(AudioManager.STREAM_ALARM)*0.8), AudioManager.FLAG_REMOVE_SOUND_AND_VIBRATE);
         mgr.setStreamVolume(AudioManager.STREAM_SYSTEM, (int) (mgr.getStreamMaxVolume(AudioManager.STREAM_SYSTEM)*0.8), AudioManager.FLAG_REMOVE_SOUND_AND_VIBRATE);
         mgr.setStreamVolume(AudioManager.STREAM_NOTIFICATION, (int) (mgr.getStreamMaxVolume(AudioManager.STREAM_NOTIFICATION)*0.8), AudioManager.FLAG_REMOVE_SOUND_AND_VIBRATE);
    }
    Log.d("SService", "m1");
    EventAlarmReceiver.completeWakefulIntent(intent);

}

}

here is my manifest

Answer 1

You are calling:

alarmIntent = PendingIntent.getBroadcast(context, 0, intent, 0);

PendingIntent.getBroadcast(context, intent) will retrieve a pendingintent that will perform a broadcast with the context and intent that you passed. So for example it will call Context.sendBroadcast(intent), which will send the intent to all interested BroadcastReceivers.

Instead of doing:

Intent intent = new Intent(context, EventSchedulingService.class);

Try passing a BroadcastReceiver to the intent constructor.
