Question

我正在尝试为我的应用设置google登录，但是它一直失败，我单击按钮，弹出窗口，选择帐户，然后弹出Toast告诉我登录失败。有什么办法可以解决这个问题？问题出在onActivityResult()方法上，并且说吐司说“ Auth走错了”。我已经在互联网上进行了搜索，但是找不到解决方案，甚至无法找到原因。 80行是这个 Task<GoogleSignInAccount> task = GoogleSignIn.getSignedInAccountFromIntent(data);

public class SignInActivity extends AppCompatActivity {

    static final int GOOGLE_SIGN_IN = 2;
    FirebaseAuth mAuth;
    Button btn_login;
    GoogleSignInClient mGoogleSignInClient;
    FirebaseAuth.AuthStateListener mAuthListener;

    @Override
    protected void onStart() {
        super.onStart();
        mAuth.addAuthStateListener(mAuthListener);
    }

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

        btn_login = findViewById(R.id.login);
        mAuth = FirebaseAuth.getInstance();

        mAuthListener = new FirebaseAuth.AuthStateListener() {
            @Override
            public void onAuthStateChanged(@NonNull FirebaseAuth firebaseAuth) {
                if (firebaseAuth.getCurrentUser() != null) {
                    Switch();
                }
            }
        };

        GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
                .requestIdToken(getString(R.string.default_web_client_id))
                .requestEmail()
                .build();

        mGoogleSignInClient = GoogleSignIn.getClient(this, gso);

        btn_login.setOnClickListener(v -> signIn());
    }

    private void signIn() {
        Intent signInIntent = mGoogleSignInClient.getSignInIntent();
        startActivityForResult(signInIntent, GOOGLE_SIGN_IN);
    }

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

        // Result returned from launching the Intent from GoogleSignInApi.getSignInIntent(...);
        if (requestCode == GOOGLE_SIGN_IN) {
            Task<GoogleSignInAccount> task = GoogleSignIn.getSignedInAccountFromIntent(data);
            try {
                // Google Sign In was successful, authenticate with Firebase
                GoogleSignInAccount account = task.getResult(ApiException.class);
                firebaseAuthWithGoogle(account);
            } catch (ApiException e) {
                // Google Sign In failed, update UI appropriately
                Log.w("TAG", "Google sign in failed", e);
                Toast.makeText(SignInActivity.this, "Auth went wrong :/", Toast.LENGTH_SHORT).show();
                // ...
            }
        }
    }

    private void firebaseAuthWithGoogle(GoogleSignInAccount acct) {
        Log.d("TAG", "firebaseAuthWithGoogle:" + acct.getId());
        AuthCredential credential = GoogleAuthProvider.getCredential(acct.getIdToken(), null);
        mAuth.signInWithCredential(credential)
                .addOnCompleteListener(this, task -> {
                    if (task.isSuccessful()) {
                        // Sign in success, update UI with the signed-in user's information
                        Log.d("TAG", "signInWithCredential:success");
                        FirebaseUser user = mAuth.getCurrentUser();
                        Toast.makeText(SignInActivity.this, "Success!", Toast.LENGTH_SHORT).show();
                        updateUI(user);
                        Switch();
                    } else {
                        // If sign in fails, display a message to the user.
                        Log.w("TAG", "signInWithCredential:failure", task.getException());
                        Toast.makeText(SignInActivity.this, "Authentication failed.", Toast.LENGTH_SHORT).show();
                        updateUI(null);
                    }
                });
    }
}

我通过使用最新版本的appcompat库解决了类似问题。

implementation 'androidx.appcompat:appcompat:1.1.0-alpha03'

如果不是这种情况，请尝试不使用requestIdToken(getString(R.string.default_web_client_id))。如果没有发生错误，则应再次检查凭证部分。

检查以下内容：

SHA-1指纹正确吗？
SHA-1指纹是否用于调试或发布？
包裹名称正确吗？
您是否使用过网络应用类型的客户端ID？

为什么我的onActivityResult（）总是返回false？
