Always show service in notification bar

Question

I want to add my app to the notification bar so that it always shows, like some apps in the Google Play store.

I want it to be like this screen shot:

Answer 1

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

private void 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);




    // Gets an instance of the NotificationManager service
    NotificationManager mNotifyMgr =
            (NotificationManager) getSystemService(NOTIFICATION_SERVICE);

    // Build the notification and issues it.
    mNotifyMgr.notify(mNotificationId, mBuilder.build());


}
