Firebase 电子邮件/密码身份验证从未完成

Question

I implement email/password sign-in method provided by Firebase in my Android apps. It was working fine. But today it didn't work for some reasons unknown to me. I didn't change any codes related to my login activity and didn't change the settings in my Firebase console.

private void signIn(String email, String password) {
    Log.d(TAG, "signIn:" + email);
    if (!validateForm()) {
        return;
    }

    showProgressDialog();

    // [START sign_in_with_email]
    firebaseAuth.signInWithEmailAndPassword(email, password)
            .addOnCompleteListener(this, task -> {
                if (task.isSuccessful()) {
                    // Sign in success, update UI with the signed-in user's information
                    Log.d(TAG, "signInWithEmail:success");
                    FirebaseUser user = firebaseAuth.getCurrentUser();
                    updateUI(user);
                } else {
                    // If sign in fails, display a message to the user.
                    Log.w(TAG, "signInWithEmail:failure", task.getException());
                    Toast.makeText(LoginActivity.this, "Authentication failed.",
                            Toast.LENGTH_SHORT).show();
                }

                hideProgressDialog();
            });
    // [END sign_in_with_email]
}

In the Logcat, it showed that the program did reach the sign in method, but somehow the authentication process never completed (the log never shows signInWithEmail:success or signInWithEmail:failure).

I did try other solution such as changing addOnCompleteListener to addOnSuccessListener but nothing changed. Is Firebase service currently not working? Or is there something wrong with my codes? I'm completely at lost. I appreciate any thoughts you'd like to share.

Answer 1

I managed to make it work again by creating a new emulator with x86_64 SDK . I think it's related with this question and this question

Answer 2

Did you logout ? Try to logout first and then it will sign in.

Try doing firebaseAuth.signOut() in your onCreate method. It might help.

Answer 3

但此日志指的是方法 (SignIn) 而不是 firebaseAuth 方法，请从 Tools->Firebase -> Authentication -> Connect to Firebase（如果未连接）检查您与 Firebase 的连接

Answer 4

I had another task FirebaseAuth.getInstance().currentUser.getIdToken(true). It never completed because I called it from the main thread. When I called from the background thread - it completed.
