Notification is shown everytime I close the app

Question

I created a notification which is shown at specific time, but the problem is that everytime I close the app (after the prefixed time) the noification is shown. How can I fix this issue?

This is my code: Home.class (is a fragment)

Calendar calend = Calendar.getInstance();
        calend.setTimeInMillis(System.currentTimeMillis());
        calend.set(Calendar.HOUR_OF_DAY, 9);
        calend.set(Calendar.MINUTE, 27);
        calend.set(Calendar.SECOND, 0);
        Intent myIntent = new Intent(getActivity(), MyReceiver.class);
        pendingIntent = PendingIntent.getBroadcast(getActivity(), 0, myIntent,0);
        AlarmManager alarmManager = (AlarmManager)getActivity().getSystemService(Context.ALARM_SERVICE);
        alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calend.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent);

MyReceiver.class

public class MyReceiver extends BroadcastReceiver
{

    @Override
    public void onReceive(Context context, Intent intent)
    {


       Intent service1 = new Intent(context, MyAlarmService.class);
       context.startService(service1);

    }   
}

MyAlarmService.class

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", "deprecation" })
   @Override
   public void onStart(Intent intent, int startId)
   {
       super.onStart(intent, startId);

       mManager = (NotificationManager) this.getApplicationContext().getSystemService(this.getApplicationContext().NOTIFICATION_SERVICE);
       Intent intent1 = new Intent(this.getApplicationContext(),MainActivity.class);

       Notification notification = new Notification(R.drawable.ic_launcher,"This is a test message!", System.currentTimeMillis());
       intent1.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP| Intent.FLAG_ACTIVITY_CLEAR_TOP);

       PendingIntent pendingNotificationIntent = PendingIntent.getActivity( this.getApplicationContext(),0, intent1,PendingIntent.FLAG_UPDATE_CURRENT);
       notification.flags |= Notification.FLAG_AUTO_CANCEL;
       notification.setLatestEventInfo(this.getApplicationContext(), "AlarmManagerDemo", "This is a test message!", pendingNotificationIntent);

       mManager.notify(0, notification);
    }

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

}

I have an answer for this.

don't use service for the same. you just need to write the below code in your MyReceiver class and it will not give you notification when you kill the app from task manager.

public class AlarmReceiver extends BroadcastReceiver {
        private NotificationManager mManager;

        private static final int MY_NOTIFICATION_ID = 1;
        private static final String TAG = "AlarmNotificationReceiver";

        // Notification Text Elements
        private final CharSequence tickerText = "its ok?";
        private final CharSequence contentTitle = " Reminder1";
        private final CharSequence contentText = "reminder content";

        // Notification Action Elements
        private Intent mNotificationIntent;
        private PendingIntent mContentIntent;

         @Override
         public void onReceive(Context context, Intent intent) {
         // When our Alaram time is triggered , this method will be excuted (onReceive)



             mNotificationIntent = new Intent(context, MyView.class);

             // The PendingIntent that wraps the underlying Intent
             mContentIntent = PendingIntent.getActivity(context, 0,mNotificationIntent,PendingIntent.FLAG_UPDATE_CURRENT);

             // Build the Notification
             Notification.Builder notificationBuilder = new Notification.Builder(
                     context).setTicker(tickerText)
                     .setSmallIcon(android.R.drawable.stat_sys_warning)
                     .setAutoCancel(true).setContentTitle(contentTitle)
                     .setContentText(contentText).setContentIntent(mContentIntent);

             // Get the NotificationManager
             NotificationManager mNotificationManager = (NotificationManager)context
                     .getSystemService(Context.NOTIFICATION_SERVICE);

             // Pass the Notification to the NotificationManager:
             mNotificationManager.notify(MY_NOTIFICATION_ID,
                     notificationBuilder.build());

        }

    }

Has you can read in this post : Will AlarmManager work if my application is not running? The AlarmManager keep you Alarm until the device is reboot OR if you kill the app. Remove it from the recent list will kill the app.

This did not explain why the notification is shown but I guess the system execute your request during the killing. It should just remove it but maybe (no proof here) it prefere to send the broadcast insteed
