Alarm Manager Pending Intent not firing Service


I have an alarm that I want to set off every 10 minutes, but it is not firing. Here is where I am setting up the AlarmService in my MainActivity. And yes, I've declared the WAKE_LOCK permission.

Calendar cal2 = Calendar.getInstance();
cal2.add(Calendar.MINUTE, 1);
PendingIntent getSqlUpdatesTimer = PendingIntent.getService(this, 0, new Intent(AlarmService.PULL_SQLUPDATES_ACTION, null, this, AlarmService.class), 0);
alarmManager.cancel(getSqlUpdatesTimer);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, cal2.getTimeInMillis(), 600000, getSqlUpdatesTimer);

Here is my alarm Service:

public class AlarmService extends Service {
    public static final String PULL_SQLUPDATES_ACTION = "com.mycompany.AlarmService.PULL_SQLUPDATES";

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
    if (intent != null) {
        if (PULL_SQLUPDATES_ACTION.equals(intent.getAction())) {
            PowerManager pm = (PowerManager)getSystemService(POWER_SERVICE);
            WakeLock wl = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, TAG);
            wl.acquire();

            GetSQLUpdates retrieveSQLUpdates = new GetSQLUpdates(null);
            retrieveSQLUpdates.execute("sp_A_Get_SQLUpdates", "sp_A_Put_SQLUpdates");

            wl.release();
        }
    }
    return START_STICKY;
}
}

What am I missing?


Solution

  • I wasn't able to get it to start this way, so I used a BroadcastReceiver instead of a service from this answer:

    Alarm Manager Example:

        cal.set(Calendar.HOUR_OF_DAY, 0);
        cal.set(Calendar.MINUTE, 0);
        cal.set(Calendar.SECOND, 0);
    
        //set the alarms 5 minutes apart so they don't conflict.
        cal.add(Calendar.MILLISECOND,GlobalVars.timeToCheckForKillMe);
    
        //getSqlUpdatesTimer = PendingIntent.getService(this, 0, new Intent(AlarmService.PULL_SQLUPDATES_ACTION, null, this, AlarmService.class), 0);
        Intent i = new Intent(this, AlarmBroadcastReceiver.class);
        getSqlUpdatesTimer = PendingIntent.getBroadcast(this, 0, i, 0);
        alarmManager.cancel(getSqlUpdatesTimer);
        alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), GlobalVars.timeToCheckForKillMe, getSqlUpdatesTimer);
    

    And the class:

    public class AlarmBroadcastReceiver extends BroadcastReceiver {
    
    @Override
    public void onReceive(Context context, Intent intent)
    {
        if (intent != null) {
    
                PowerManager pm = (PowerManager)context.getSystemService(context.POWER_SERVICE);
                PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, TAG);
                wl.acquire();
    
                EDiaryDataSync.GetSQLUpdates retrieveSQLUpdates = new EDiaryDataSync.GetSQLUpdates(null);
                retrieveSQLUpdates.execute("sp_A_Get_SQLUpdates", "sp_A_Put_SQLUpdates");
    
                wl.release();
        }
    
    }
    }
