Can't write to Firebase database

I can't write to Firebase. I use exactly as in the tutorial but it's not working.

    @Override
protected void onCreate (Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.welcome);

FirebaseDatabase database = FirebaseDatabase.getInstance();
DatabaseReference myRef = database.getReference();
myRef.setValue("aaa");
...

Also I have changed the rules to:

{
"rules": {
".read": "true",
".write": "true"
   }
}

Also my google-services.json is just downloaded from the project.

In my case, as of March 2021, it seems the problem was the classpath of Gradle dependency that caused the issue.

In Project-Level build.gradle:
I have changed:

    dependencies {
        classpath "com.android.tools.build:gradle:4.1.2"
        classpath 'com.google.gms:google-services:4.3.5'
    }

to:

    dependencies {
        classpath "com.android.tools.build:gradle:4.1.3"
        classpath 'com.google.gms:google-services:4.3.5'
    }

You need to specify the reference branch in the database.getReference() like:

database.getReference("reference name")

You can't set the main branch value, you can only add references to it.
