Open application after clicking on Notification

See below code. I am using that and it is opening my HomeActivity.

    NotificationManager notificationManager = (NotificationManager) context
            .getSystemService(Context.NOTIFICATION_SERVICE);
    Notification notification = new Notification(icon, message, when);

    Intent notificationIntent = new Intent(context, HomeActivity.class);

    notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP
            | Intent.FLAG_ACTIVITY_SINGLE_TOP);

    PendingIntent intent = PendingIntent.getActivity(context, 0,
            notificationIntent, 0);

    notification.setLatestEventInfo(context, title, message, intent);
    notification.flags |= Notification.FLAG_AUTO_CANCEL;
    notificationManager.notify(0, notification);

Looks like you missed this part,

notification.contentIntent = pendingIntent;

Try adding this and it should work.

Here's example using NotificationCompact.Builder class which is the recent version to build notification.

private void startNotification() {
    Log.i("NextActivity", "startNotification");

 // Sets an ID for the notification
      int mNotificationId = 001;

    // Build Notification , setOngoing keeps the notification always in status bar
    NotificationCompat.Builder mBuilder =
            new NotificationCompat.Builder(this)
                    .setSmallIcon(R.drawable.ldb)
                    .setContentTitle("Stop LDB")
                    .setContentText("Click to stop LDB")
                    .setOngoing(true);

    // Create pending intent, mention the Activity which needs to be 
    //triggered when user clicks on notification(StopScript.class in this case)

    PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
            new Intent(this, StopScript.class), PendingIntent.FLAG_UPDATE_CURRENT);


    mBuilder.setContentIntent(contentIntent);


    // Gets an instance of the NotificationManager service
   NotificationManager mNotificationManager =
            (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);


    // Builds the notification and issues it.
    mNotificationManager.notify(mNotificationId, mBuilder.build());


}
