I have a code snippet here to send a notification from a device to multiple devices:

public static void sendNotificationToUser(final String message) {

    Firebase ref = new Firebase("https://danger-alarm.firebaseio.com/");
    final Firebase notifications = ref.child("danger-alarm");

    Map notification = new HashMap<>();
    notification.put("message",message);

    notifications.push().setValue(notification);
}

How my Firebase database looks like:

But the problem is, when I execute these codes, it doesn't send anything

I have a problem with the **builder()** method in the code snippets – fant293 Jul 20 '19 at 14:24

This syntax `new Firebase("https://danger-alarm.firebaseio.com/")` is over four years old. Please find a newer Firebase tutorial to follow, or use the official documentation: https://firebase.google.com/docs/database/android/start. – Frank van Puffelen Jul 20 '19 at 14:33
@amin OP is not using FCM, but the Realtime Database. – Frank van Puffelen Jul 20 '19 at 14:34
