Firebase Facebook 身份验证显示奇怪 activity

Question

我们正在为我们的一个项目实施 Firebase Facebook 身份验证。我们也遵循了文档中提到的步骤。

这是 oAuth URL:

https://<APP_NAME>.firebaseapp.com/__/auth/handler

我也添加了其余的凭据（即 APP_ID 和 APP_SECRET），而且应用程序处于开发阶段，我添加了 key hash以及 Facebook 门户和 Firebase 门户。

Login初始流程运行良好，但是当用户confirm授予访问权限时，callback寄存器根本没有响应，[=19] =] 也不 positive 致谢。

这是我们的代码片段：

     private static final String TAG = "FacebookLogin";

    private CallbackManager mCallbackManager;

    private FirebaseAuth mAuth;
    private FirebaseAuth.AuthStateListener mAuthListener;

 mAuth = FirebaseAuth.getInstance();
        mAuthListener = new FirebaseAuth.AuthStateListener() {
            @Override
            public void onAuthStateChanged(@NonNull FirebaseAuth firebaseAuth) {
                FirebaseUser user = firebaseAuth.getCurrentUser();
                if (user != null) {
                    // User is signed in
                    Log.d(TAG, "onAuthStateChanged:signed_in:" + user.getUid());
                } else {
                    // User is signed out
                    Log.d(TAG, "onAuthStateChanged:signed_out");
                }
                // ...
            }
        };

        // Initialize Facebook Login button
        mCallbackManager = CallbackManager.Factory.create();
        LoginButton loginButton = (LoginButton) findViewById(R.id.button_facebook_login);
        loginButton.setReadPermissions("email", "public_profile");
        loginButton.registerCallback(mCallbackManager, new FacebookCallback<LoginResult>() {
            @Override
            public void onSuccess(LoginResult loginResult) {
                Log.d(TAG, "facebook:onSuccess:" + loginResult);
                handleFacebookAccessToken(loginResult.getAccessToken());
            }

            @Override
            public void onCancel() {
                Log.d(TAG, "facebook:onCancel");
                // ...
            }

            @Override
            public void onError(FacebookException error) {
                Log.d(TAG, "facebook:onError"+ error);
                // ...
            }
        });

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

    @Override
    public void onStop() {
        super.onStop();
        if (mAuthListener != null) {
            mAuth.removeAuthStateListener(mAuthListener);
        }
    }

    private void handleFacebookAccessToken(AccessToken token) {
        Log.d(TAG, "handleFacebookAccessToken:" + token);

        AuthCredential credential = FacebookAuthProvider.getCredential(token.getToken());
        mAuth.signInWithCredential(credential)
                .addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
                    @Override
                    public void onComplete(@NonNull Task<AuthResult> task) {
                        Log.d(TAG, "signInWithCredential:onComplete:" + task.isSuccessful());

                        // If sign in fails, display a message to the user. If sign in succeeds
                        // the auth state listener will be notified and logic to handle the
                        // signed in user can be handled in the listener.
                        if (!task.isSuccessful()) {
                            Log.w(TAG, "signInWithCredential", task.getException());
                            Toast.makeText(FacebookLoginActivity.this, "Authentication failed.",
                                    Toast.LENGTH_SHORT).show();
                        }

                        // ...
                    }
                });
    }

如果我们遗漏了什么，请告诉我们。我假设 callback URL 有问题，因此更多关于相同内容的信息会有所帮助，因为 Firebase 文档没有明确说明如何构建 URL .提前致谢。

你添加了吗

mCallbackManager.onActivityResult(requestCode, resultCode, data);

在你的 onActivityResult 块中？

编辑

参考来自 Firebase https://github.com/firebase/quickstart-android/blob/master/auth/app/src/minSdkJellybean/java/com/google/firebase/quickstart/auth/FacebookLoginActivity.java、

的示例

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

不加这个就没有回调
