notification at a certain time everyday

Question

Hi I'm new to Android. I want to notify the user everyday at a certain time. I tried to use AlarmManager fires up a Service, in this Service I set up a notification. My codes are below and they are not working right now:

My alarm service code:

public class MyAlarmService extends Service 
{

   private NotificationManager mManager;

    @Override
    public IBinder onBind(Intent arg0)
    {
       // TODO Auto-generated method stub
        return null;
    }

    @Override
    public void onCreate() 
    {
       // TODO Auto-generated method stub  
       super.onCreate();
    }

   @SuppressWarnings("static-access")
   @Override
   public void onStart(Intent intent, int startId)
   {
       Intent intents = new Intent(getBaseContext(), MainActivity.class);
       intents.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
                | Intent.FLAG_ACTIVITY_SINGLE_TOP);
       PendingIntent m_PendingIntent = PendingIntent.getActivity(
                getBaseContext(), 0, intents, PendingIntent.FLAG_UPDATE_CURRENT);
       mManager = (NotificationManager) this.getApplicationContext().getSystemService(this.getApplicationContext().NOTIFICATION_SERVICE);



       NotificationCompat.Builder mBuilder =
                new NotificationCompat.Builder(this)
                .setSmallIcon(R.drawable.ic_launcher)
                .setContentTitle("My notification")
                .setContentText("Hello World!")
                .setDefaults(Notification.DEFAULT_SOUND
                | Notification.DEFAULT_VIBRATE);

       mBuilder.setContentIntent(m_PendingIntent);

       mManager.notify(0, mBuilder.build());
    }

    @Override
    public void onDestroy() 
    {
        // TODO Auto-generated method stub
        super.onDestroy();
    }

}

My receiver code:

public class MyReceiver extends BroadcastReceiver
{

    @Override
    public void onReceive(Context context, Intent intent)
    {
       Intent service1 = new Intent(context, MyAlarmService.class);
       context.startService(service1);

    }   
}

code in MainActivity:

Intent myIntent = new Intent(MainActivity.this, MyReceiver.class);
        pendingIntent = PendingIntent.getBroadcast(MainActivity.this, 0, myIntent,0);

        AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
        alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, c.getTimeInMillis(), 1000 * 60 * 60 * 24, pendingIntent);

Right now, the notification will not show up after I set the time. Where is my problem?

Also, use `Context.NOTIFICATION_SERVICE` instead of `this.getApplicationContext().NOTIFICATION_SERVICE`. Since this is a static constant you can directly use the Context class to refer to it. You won't need the `@SuppressWarnings("static-access")` then :) — Shivam Verma, Jul 24 '14 at 10:37

You should override the onStartCommand() method in your Service in place of onStart(). The onStart() method is called only on pre Android 2.0 Platforms. On the later versions of Android, only the onStartCommand() is called.

Reference.

So I just change onStart() to onStartCommand(), I see the example it returns START_STICKY, what is this? – SuShiS Jul 24 '14 at 10:21
Returning START_STICKY makes sure that the Service is never stopped by android until the app explicitly stops it. – Shivam Verma Jul 24 '14 at 10:35
