I am new to Android and I have been trying to show a Heads up action push notification just like whatsapp does.

This is my configuration for my notification:

NotificationCompat.Builder notificationBuilder =

                new NotificationCompat.Builder(this, ADMIN_CHANNEL)

                        .setLargeIcon(BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher_foreground))

                        .setSmallIcon(R.drawable.m_icon)

                        .setContentTitle(remoteMessage.getNotification().getTitle())

                        .setTicker(remoteMessage.getNotification().getBody())

                        .setColor(ContextCompat.getColor(getApplicationContext(), R.color.mblue))

                        .setAutoCancel(true)

                        .setSound(defaultSoundUri)

                        .setStyle(new NotificationCompat.BigTextStyle()

                                .bigText(remoteMessage.getNotification().getBody()))

                        .setPriority(NotificationCompat.PRIORITY_HIGH)

                        .setContentIntent(likePendingIntent);



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

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

I have read in some post that the key to acomplish this is to set high priority to the notification but, It is still not working for me.

The issue is that we have to add a new channel configuration whenever the OS is Oroe. So I had to validate if the OS is Oreo and then asign a channel to my notificationManager:

NotificationManager notificationManager =

                    (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);



if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {

    setupChannels();

}



@RequiresApi(api = Build.VERSION_CODES.O)

private void setupChannels(){

    CharSequence adminChannelName ="Global channel";

    String adminChannelDescription = "Notifications sent from the app admin";

    NotificationChannel adminChannel;

    adminChannel = new NotificationChannel(ADMIN_CHANNEL_ID, adminChannelName, NotificationManager.IMPORTANCE_HIGH);

    adminChannel.setDescription(adminChannelDescription);

    adminChannel.enableLights(true);

    adminChannel.setImportance(NotificationManager.IMPORTANCE_HIGH);

    adminChannel.setLightColor(Color.RED);

    adminChannel.enableVibration(true);

    if (notificationManager != null) {

        notificationManager.createNotificationChannel(adminChannel);

    }



}
