Intent myIntent = new Intent(MainActivity.this, ContactsActivity.class);

I am trying to use FCM to make push notifications but when I use the FCM test notification system, I don't recieve any notification. I don't think I need any code for that purpose except for my registration token which I obtain like this
String refreshedToken = FirebaseInstanceId.getInstance().getToken();
I then store it in a database and copy-paste it so that there is no change. But still I am not recieving any notification. I even added the onMessageRecieved function
public void onMessageReceived(RemoteMessage remoteMessage) {
// ...
if (remoteMessage.getData().size() > 0) {
// Handle message within 10 seconds
handleNow(remoteMessage.getNotification().getBody());
}
if (remoteMessage.getNotification() != null) {
// Log.d(TAG, "Message Notification Body: " + remoteMessage.getNotification().getBody());
}
}
public void handleNow(String body) {
Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder builder = new NotificationCompat.Builder(this,"Alerts")
.setSmallIcon(R.drawable.logo)
.setContentTitle("Stice Alerts")
.setContentText(body)
.setPriority(NotificationCompat.PRIORITY_MAX)
.setSound(defaultSoundUri)
.setStyle(new NotificationCompat.BigTextStyle()
.bigText(body));
NotificationManagerCompat notificationManager = NotificationManagerCompat.from(this);
notificationManager.notify(100,builder.build());
}
Here is my notification channel
private void createNotificationChannel() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
CharSequence name = "Alerts";
String description = "For alerts when someone is going";
int importance = NotificationManager.IMPORTANCE_HIGH;
NotificationChannel channel = new NotificationChannel("Alerts",name,importance);
channel.setDescription(description);
NotificationManager notificationManager = getSystemService(NotificationManager.class);
notificationManager.createNotificationChannel(channel);
}
}

Can anyone tell me what I might be doing wrong?
While sending out your notifications from Firebase Cloud Messaging, make sure the channel set is equal to your channel name Alerts
I am learning to develop apps for Android but I am stuck with this topic:

I have visited numerous sites with examples, downloaded source code and tried in two different computers with Android Studio and tried in a virtual and physical device, but I can't figure out where the problem is.
