大家好，我正在为我的项目构建一个 Android 应用程序，但 Facebook 登录时出现错误，并且 Twitter 登录无法正常工作

        }

    }

}

Google 登录工作正常，但有 2 个错误

1. 我收到错误“Unhandled Exception LoginManager.onResultActivity”，代码直接跳转到 Facebook 登录中的登录部分和授权部分之后的错误 block 。

2.我已经为twitter编写了代码，但是尽管我已经在上面的代码中编写了，但没有触发任何点击事件。

我猜这两个错误在下面的代码中，但不确定

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

//TO DO:Error occurs of facebook and Twitter is not working

            if (requestCode == request_code)
            {
                GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data);
                handleResult(result);
            }
            else if(requestCode==TwitterAuthConfig.DEFAULT_AUTH_REQUEST_CODE)
        {
            // Pass the activity result to the login button.
            signInButtonTwitter.onActivityResult(requestCode, resultCode, data);
        }
        else
            {
                FBcallbackManager.onActivityResult(requestCode,requestCode,data);

            }
        }

我陷入了我的项目，请有人帮助我，谢谢

试试这个方法..

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


                        if (requestCode == request_code)
                        {
                            GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data);
                            handleResult(result);
                        }
        }
