取消时出现 Android Google 登录错误

Question

我遇到了一些无法解决的奇怪问题。我有一个使用 Google 登录的 Android 应用程序。该应用程序遵循 MVP 模式并使用 fragment 而不是 Activity 。登录部分来自这里: https://developers.google.com/identity/sign-in/android/

一切正常，直到我尝试通过在其外部点击来关闭登录对话框(您在其中选择用户)。我假设它应该给我一个状态代码 12501 (SIGN_IN_CANCELLED) 但我得到的是代码 13 (ERROR)。我的假设错了吗？如果发生错误，我是否应该忽略代码 13 并且不向用户显示任何错误？

下面是最相关的代码

Activity :

public class SignInActivity extends AppCompatActivity implements SignInFragment.SignInListener {    

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

        // Add sign in fragment
        mSignInFragment = new SignInFragment();
        FragmentManager fragmentManager = getSupportFragmentManager();
        fragmentManager
                .beginTransaction()
                .replace(R.id.sign_in_frame, mSignInFragment, TAG)
                .commit();
    }

    @Override
    public void startSignIn() {
        Intent signInIntent = mSignInFragment.getGoogleSignInClient().getSignInIntent();
        startActivityForResult(signInIntent, RC_SIGN_IN);
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if (requestCode == RC_SIGN_IN) {
            Task<GoogleSignInAccount> task = GoogleSignIn.getSignedInAccountFromIntent(data);
            mSignInFragment.handleSignInResult(task);
        }
    }
}

fragment :

public class SignInFragment extends DaggerFragment implements SignInContract.View, GoogleApiClient.OnConnectionFailedListener {

    private SignInFragment.SignInListener signInListener;

    public interface SignInListener {
        void startSignIn();
        void startMainActivity();
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

        GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
                .requestIdToken( clientId )
                .build();

        mGoogleSignInClient = GoogleSignIn.getClient(getActivity(), gso);

        // Calling this to force user select dialog to appear everytime
        mGoogleSignInClient.signOut();

        signInButton.setOnClickListener(v -> {
            signInListener.startSignIn();
        }
    }

    protected void handleSignInResult(Task<GoogleSignInAccount> task) {
        try {
            GoogleSignInAccount acct = task.getResult(ApiException.class);
            String idToken = acct.getIdToken();
            presenter.deliverTokenToServer(idToken);

        } catch (ApiException e) {
            e.printStackTrace();
            Log.d(TAG, "handleSignInResult:" + e.getStatusCode());
            Snackbar snackbar = Snackbar.make(getView(), R.string.error_login_failed_try_again, Snackbar.LENGTH_LONG);
            snackbar.show();

        }
    }
}

在 gradle 文件中，我使用了 'com.google.android.gms:play-services-auth:15.0.1' 和 'com.google.gms:google-服务:4.0.1'

Answer 1

我终于找到了。这是 Google Play 库中的回归。并且它已在 play-services-auth:16.0.0 中修复。这是一些details .

implementation com.google.android.gms:play-services-auth:16.0.0
