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
- 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
最佳答案
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);
}
}
关于java - 在单个 Activity 中连接 facebook、twitter 和 google android onActivityResult 错误，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/42807847/
