Android app not writing to firebase database

Question

I know this question has been asked before, but I've tried just about every posted solution and have been unsuccessful. I set up my Firebase realtime database with the Firebase documentation and followed everything properly. I set read and write values both to true (only for testing; will change later). This is my code:

package com.example.classfinder;

import androidx.appcompat.app.AppCompatActivity;

import android.os.Bundle;

import com.google.firebase.database.DatabaseError;
import com.google.firebase.database.DatabaseReference;
import com.google.firebase.database.FirebaseDatabase;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        // init commit

        FirebaseDatabase.getInstance().getReference().child("name").push().setValue("hello, world!");

    }
}

I know my Gradle files are good since I followed the documentation to the dot and did my research. When I write to the database, nothing shows up. Let me know if you need more info to answer this question. Thanks!!

EDIT 1: IMAGE OF DATABASE:

EDIT 2: Resolved by turning of wifi and using mobile data instead.

Answer 1

Here is the solution, probably. Worked for me, if you used a database in a different region, you need to specify that in google-services.json

Firebase Database connection was forcefully killed by the server: Different region #flutter
