        super.onCreate(savedInstanceState);

                            updateUI(user);
                        } else {
                            // If sign in fails, display a message to the user.
                            Log.w("Error", "signInWithEmail:failure", task.getException());
                            Toast.makeText(PassageiroActivity.this, "Authentication failed.",

                            updateUI(null);
                        }

                        // ...

                    String user_id = mAuth.getCurrentUser().getUid();
                    DatabaseReference current_user_db = FirebaseDatabase.getInstance().getReference().child("Users").child("Passageiro").child(user_id);
                    current_user_db.setValue(true);
                    
                } else {
                    // If sign in fails, display a message to the user.
                    Log.w("Error", "createUserWithEmail:failure", task.getException());

                    updateUI(null);
                }
            }

            });


    }

}

Segue meu build.gradle:

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'androidx.appcompat:appcompat:1.1.0'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
    implementation 'com.google.android.material:material:1.1.0'
    //implementation 'androidx.annotation:annotation:1.1.2'
    implementation 'androidx.lifecycle:lifecycle-extensions:2.2.0'
    implementation 'com.google.firebase:firebase-auth:19.2.0'
    implementation 'com.google.firebase:firebase-database:19.2.1'

}

Não apresenta erro somente não joga no banco

mTeste.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                try {
                    FirebaseDatabase database = FirebaseDatabase.getInstance();
                    DatabaseReference myRef = database.getReference("message");
                    myRef.setValue("Hello, World!");
                }
                catch(Exception e){
                    Log.d("asd",e.getMessage());
                }
            }
        });

Olha como está a permissão no seu banco de dados:

Clica em “Regras”
1- image

Depois coloca o read e write como true.
2- image

Obs:

É sempre bom deixar as coisas organizadas para não ter duplicidades.

Gradle:

//Arquivos .Jar
implementation fileTree(dir: 'libs', include: ['*.jar'])

//Test Library
testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test.ext:junit:1.1.1'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'

//AndroidX + Material Design Library
implementation 'androidx.appcompat:appcompat:1.1.0'
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
implementation 'com.google.android.material:material:1.1.0'
//implementation 'androidx.annotation:annotation:1.1.2'
implementation 'androidx.lifecycle:lifecycle-extensions:2.2.0'

//Firebase
implementation 'com.google.firebase:firebase-auth:19.2.0'
implementation 'com.google.firebase:firebase-database:19.2.1'
implementation 'com.google.firebase:firebase-core:17.2.2'

Utilizando esse Código ele aparece no console

image.png1269×177 9.18 KB 

public void mandarDados(){
    FirebaseDatabase database = FirebaseDatabase.getInstance();
    DatabaseReference myRef = database.getReference("message");
    myRef.setValue("Hello, World!");
    Log.d("aqui","aqui");

    myRef.addValueEventListener(new ValueEventListener() {
        @Override
        public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
            String value = dataSnapshot.getValue(String.class);
            Log.d("Main", "Value is: " + value);
        }

        @Override
        public void onCancelled(@NonNull DatabaseError databaseError) {
            Log.w("Main", "Failed to read value.", databaseError.toException());

        }
    });

}

Porém ainda continua não mandando:

Consegui resolver, fiz um projeto do zero e somente utilizei a assistente do android studio fazendo a instalação somente por ele
