title: How to create multiple local notifications in android
body: <p>In my android app I need to show multiple local notifications on a particular day at different time intervals,I used alarm manager and broadcast receiver to do for one notification but when I was trying to implement multiple notifications only the second one is been displayed.</p>
  
  <p>Here is my MainActivity</p>
  
  <pre><code>    AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
  
      Intent notificationIntent = new Intent("android.media.action.DISPLAY_NOTIFICATION");
      notificationIntent.addCategory("android.intent.category.DEFAULT");
  
      PendingIntent broadcast = PendingIntent.getBroadcast(this, 100, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
  
      Calendar cal = Calendar.getInstance();
      cal.set(2015, 10, 23, 15, 03);
      alarmManager.setExact(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), broadcast);
  </code></pre>
  
  <p>Here is BroadcastReceiver</p>
  
  <pre><code>Intent notificationIntent = new Intent(context, MainActivity.class);
  
      TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);
      stackBuilder.addParentStack(MainActivity.class);
      stackBuilder.addNextIntent(notificationIntent);
  
      PendingIntent pendingIntent1 = stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);
  
      NotificationCompat.Builder builder = new NotificationCompat.Builder(context);
  
      Notification notification = builder.setContentTitle("TRR - 2016")
              .setContentText("Station - 1 closed grace period only 10min")
              .setTicker("New Message Alert!")
              .setSmallIcon(R.mipmap.ic_launcher)
              .setDefaults(Notification.DEFAULT_SOUND)
              .setContentIntent(pendingIntent1).build();
  
      NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
      notificationManager.notify(mCounter, notification);
  
  Notification notification1 = builder.setContentTitle("TRR - 2016")
              .setContentText("Station - 2 closed grace period only 10min")
              .setTicker("New Message Alert!")
              .setSmallIcon(R.mipmap.ic_launcher)
              .setDefaults(Notification.DEFAULT_SOUND)
              .setContentIntent(pendingIntent1).build();
  
      NotificationManager notificationManager1 = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
      notificationManager1.notify(++mCounter, notification1);
  </code></pre>
