Service calling itself with AlarmManager

Question

I have an app that calls a Service with the AlarmManager on the main activity and inside that Service makes another alarm to call itself moments after. The alarm in the main activity works fine but the alarm in the Service doesn't set off. Anyone know why?

This is the alarm in my main activity:

Intent i = new Intent(this, DailyLogsService.class);

    Calendar time=Calendar.getInstance();
    time.set(Calendar.HOUR_OF_DAY,13);

    time.set(Calendar.MINUTE,15);
    time.set(Calendar.SECOND,0);

    AlarmManager alarmM=(AlarmManager)getSystemService(ALARM_SERVICE);
    PendingIntent pending= PendingIntent.getService(getApplicationContext(),0,i,0);
    //alarmM.cancel(pending);
    alarmM.set(AlarmManager.RTC_WAKEUP, time.getTimeInMillis(), pending);
    Toast.makeText(this, "STARTING", Toast.LENGTH_LONG).show();

and this is the alarm on my service

@Override
public void onCreate() {


    Intent i = new Intent(getBaseContext(), DailyLogsService.class);
    Calendar time=Calendar.getInstance();

    time.set(Calendar.HOUR_OF_DAY, 13);
    time.set(Calendar.MINUTE,30);
    time.set(Calendar.SECOND,0);

    AlarmManager alarmM=(AlarmManager)getSystemService(ALARM_SERVICE);
    PendingIntent pending= PendingIntent.getService(getApplicationContext(),0,i,0);
    alarmM.setExact(AlarmManager.RTC_WAKEUP, time.getTimeInMillis(), pending);


}

Answer 1

Move your alarm code in onCreate of the Service to onStartCommand method.

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    super.onStartCommand(intent, flags, startId);

    Intent i = new Intent(getBaseContext(), DailyLogsService.class);
    Calendar time=Calendar.getInstance();
    time.set(Calendar.HOUR_OF_DAY, 13);
    time.set(Calendar.MINUTE,30);
    time.set(Calendar.SECOND,0);

    AlarmManager alarmM=(AlarmManager)getSystemService(ALARM_SERVICE);
    PendingIntent pending= PendingIntent.getService(getApplicationContext(),0,i,0);
    alarmM.setExact(AlarmManager.RTC_WAKEUP, time.getTimeInMillis(), pending);

    return START_NON_STICKY;
}
