title: Onclick of button in custom notification not working
body: <p>I have a pause button in my notification, on click of which should go to the broadcast receiver. The following is my code:</p>
  
  <pre><code>NotificationCompat.Builder builder = new NotificationCompat.Builder(WalkTrackingActivity.this);
  remoteViews = new RemoteViews(getPackageName(), R.layout.content_user_manual);
  remoteViews.setChronometer(R.id.chronometer, SystemClock.elapsedRealtime(), null, false);
  
  Intent intent = new Intent(WalkTrackingActivity.this, WalkTrackingActivity.class);
  intent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_CLEAR_TOP);
  PendingIntent pendingIntent = PendingIntent.getActivity(WalkTrackingActivity.this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
  
  Intent fillInIntent = new Intent(this, pauseButtonListener.class);
  fillInIntent.setPackage(getPackageName());
  fillInIntent.setAction("PAUSE");
  PendingIntent templateIntent = PendingIntent.getBroadcast(this, 0, fillInIntent, PendingIntent.FLAG_UPDATE_CURRENT);
  remoteViews.setPendingIntentTemplate(R.layout.content_user_manual, templateIntent);
  RemoteViews btnView=new RemoteViews (getPackageName(),R.id.imageButton5);
  btnView.setOnClickFillInIntent(R.id.imageButton5, fillInIntent);
  
  
  
  notification = builder
          .setSmallIcon(getNotificationIcon())
          .setContentIntent(pendingIntent)
          .setAutoCancel(true)
          .setOnlyAlertOnce(true)
          .setContent(remoteViews)
          .build();
  notification.flags = Notification.FLAG_ONGOING_EVENT;
  notificationManager = (NotificationManager)
          WalkTrackingActivity.this.getSystemService(Context.NOTIFICATION_SERVICE);
  
  
  notificationManager.notify(0, notification);
  </code></pre>
