Khi tôi sử dụng signInWithEmailAndPassword() để đăng nhập onAuthStateChanged() luôn kích hoạt hai lần.Firebase Android onAuthStateChanged() kích hoạt hai lần sau khi signInWithEmailAndPassword()
Tôi chắc chắn rằng việc nghe chỉ được thêm một lần vào firebaseAuth, and I have the code in onStop() `để xóa người nghe sau đó.
Bất kỳ ai biết cách giải quyết vấn đề này?
Mã của tôi:
public class SignInActivity extends BaseActivity implements
View.OnClickListener,
GoogleApiClient.OnConnectionFailedListener{
private static final String PREF_KEY_USER_EMAIL = "User_Email";
private static final int RC_SIGN_IN = 1111;

private FirebaseAuth.AuthStateListener authStateListener;
private DatabaseReference firebaseDbReference;
private TextView fieldEmail;
private TextView fieldPassword;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_sign_in);
getSupportActionBar().hide();
firebaseAuth = FirebaseAuth.getInstance();
firebaseDbReference = FirebaseDatabase.getInstance().getReference();
fieldEmail = (TextView) findViewById(R.id.field_email);
fieldPassword = (TextView) findViewById(R.id.field_password);
String userSavedEmail = getPreferences(MODE_PRIVATE).getString(PREF_KEY_USER_EMAIL, "");
if(userSavedEmail != null) {
fieldEmail.setText(userSavedEmail);
fieldPassword.requestFocus();
}

linkForgotPassword = (TextView) findViewById(R.id.link_forgotPassword);
