android - Android 应用程序中的 Google 登录现在无法正常工作

Question

我正在开发一个使用谷歌登录过程的安卓应用程序(它已经集成到我的应用程序中)。它几个月前对我有用，但现在不起作用(谷歌更新了一些政策或其他什么!)。谁能建议这里发生了什么？提前致谢。这是我用于集成 google 登录过程的代码:

public class login extends AppCompatActivity {

private SignInButton signInButton;
private TextView textView, signT;
private static final int SIGNIN_CODE = 1;
private GoogleApiClient mGoogleApiClient;
private FirebaseAuth mAuth;
private FirebaseAuth.AuthStateListener mAuthListener;

private final static String TAG = "Login Info:";

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

    mAuth = FirebaseAuth.getInstance();
    mAuthListener = new FirebaseAuth.AuthStateListener() {
        @Override
        public void onAuthStateChanged(@NonNull FirebaseAuth firebaseAuth) {
            if (firebaseAuth.getCurrentUser() != null) {
                Intent i = new Intent(getApplicationContext(), MainActivity.class);
                i.putExtra("Val", "That i need");
                startActivity(i);
                overridePendingTransition(R.anim.fadein, R.anim.fadeout);
                finish();
            }
        }
    };

    signInButton = findViewById(R.id.SignIn);

    signT = (TextView) signInButton.getChildAt(0);
    signT.setText("Sign in with Google");

    textView = findViewById(R.id.negativetext);
    textView.setPaintFlags(textView.getPaintFlags() | Paint.UNDERLINE_TEXT_FLAG);
    textView.setText(getString(R.string.negativetext));

    textView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent i = new Intent(getApplicationContext(), MainActivity.class);
            startActivity(i);
            overridePendingTransition(R.anim.fadein, R.anim.fadeout);
            finish();
        }
    });

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

    mGoogleApiClient = new GoogleApiClient.Builder(this)
            .enableAutoManage(this, new GoogleApiClient.OnConnectionFailedListener() {
                @Override
                public void onConnectionFailed(@NonNull ConnectionResult connectionResult) {
                    Toast.makeText(getApplicationContext(), "Error", Toast.LENGTH_LONG).show();
                }
            })
            .addApi(Auth.GOOGLE_SIGN_IN_API, gso)
            .build();

    signInButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            signIn();
        }
    });

}


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

private void signIn() {
    Intent signInIntent = Auth.GoogleSignInApi.getSignInIntent(mGoogleApiClient);
    startActivityForResult(signInIntent, SIGNIN_CODE);
}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == SIGNIN_CODE) {
        Task<GoogleSignInAccount> task = GoogleSignIn.getSignedInAccountFromIntent(data);
        try {
            // Authenicate with my Firebase
            GoogleSignInAccount account = task.getResult(ApiException.class);
            ProgressDialog dialog = new ProgressDialog(this); //ProgressDialog.show(this, null, "Please wait while we load sign in..", true);
            dialog.setMessage("Please wait while we load sign in..");
            dialog.setIndeterminate(true);
            Drawable drawable = new ProgressBar(this).getIndeterminateDrawable().mutate();
            drawable.setColorFilter(ContextCompat.getColor(this, R.color.progress),
                                    PorterDuff.Mode.SRC_IN);
            dialog.setIndeterminateDrawable(drawable);
            dialog.show();

            firebaseAuthWithGoogle(account);
        } catch (ApiException e) {
            // Google Sign In failed?
            Log.w(TAG, "Google sign in failed", e);
        }
    }
}

private void firebaseAuthWithGoogle(final GoogleSignInAccount acct) {

    AuthCredential credential = GoogleAuthProvider.getCredential(acct.getIdToken(), null);

    mAuth.signInWithCredential(credential)
            .addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
                @Override
                public void onComplete(@NonNull Task<AuthResult> task) {
                    //Debugging :(
                    //Toast.makeText(getApplicationContext(), "" + task.isSuccessful(), Toast.LENGTH_LONG).show();
                    if (task.isSuccessful()) {
                        //spinner.setVisibility(ProgressBar.INVISIBLE);
                        Log.i(TAG, "signInWithCredential:success");
                    } else {
                        Toast.makeText(getApplicationContext(), "We couldn't load sign in", Toast.LENGTH_LONG).show();
                    }
                }
            });
}}

使用下面的代码，我已经使用过它并且它对我来说非常有效:

private void configureGoogleSignIn() {
 GoogleSignInOptions googleSignInOptions = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
            .requestIdToken(BuildConfig.DEFAULT_WEB_CLIENT_ID)       
            .requestEmail()
            .build();
googleSignInClient = GoogleSignIn.getClient(context, googleSignInOptions);
}

Intent signInIntent = googleSignInClient.getSignInIntent();
startActivityForResult(signInIntent, RC_SIGN_IN);

和onActivityResult

 @Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == RC_SIGN_IN) {
        Task<GoogleSignInAccount> signInAccountTask = GoogleSignIn.getSignedInAccountFromIntent(data);
        handleSignInResult(signInAccountTask);
    } else {

    }
}
