Question

How to get a heads up notification.With below code i can only see three dots on status bar and a notification in notification bar.

Intent intent = new Intent(this, MainActivity.class);

intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 , intent,PendingIntent.FLAG_ONE_SHOT);
Bitmap bm = BitmapFactory.decodeResource(getResources(), R.drawable.bip);
Uri defaultSoundUri=RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
                .setSmallIcon(R.drawable.bip)
                .setContentTitle("Temp")
                .setPriority(NotificationCompat.PRIORITY_HIGH)
                .setContentText(message)
                .setAutoCancel(true)
                .setSound(defaultSoundUri)
                .setContentIntent(pendingIntent);

NotificationManager notificationManager =
                (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

notificationManager.notify(0, notificationBuilder.build());

This code works for me:

NotificationCompat.Builder mBuilder =
                    new NotificationCompat.Builder(context)
                            .setSmallIcon(R.drawable.ic_media_play)
                            .setContentTitle("My notification")
                            .setContentText("Hello World!")
                            .setDefaults(Notification.DEFAULT_ALL)
                            .setPriority(Notification.PRIORITY_HIGH);
