Facebook android登录 [英] Facebook android login

问题描述

在下面的代码中，我正在使用提供chrome自定义标签功能的Facebook，
facebook登录屏幕正在打开Chrome（如果有Chrome浏览器的设备）或简单的webview，还有在Facebook应用程序（如果设备有应用程序）但是在授予一般权限graphapi后即使在异步调用之后也不提供任何数据，我没有得到我在做错什么，请尽可能帮助

In below code i am using facebook provided chrome custom tab feature, facebook login screen is opening in both chrome (if device having chrome browser) or else simple webview and also in facebook app (if device having app) but after granting the general permission graphapi not providing any data even after async call i'm not getting what i am doing wrong in this please help if possible

附加信息： 这是在一个片段中调用，facebook登录屏幕全部打开，只是回调不起作用，直到现在我无法找到解决方案，只得到未回答的问题，是他们的任何方式，我们可以联系Facebook关于这个。

推荐答案

最后找到解决方案。那么当你这样做的时候你必须做出

Finally found the solution. Well when you are doing this in fragment you have to make

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

在活动中也作为这个sdk触发器，在活动中你必须通过它到你的片段（用你的loginfragment替换片段）

in activity also as this sdk trigger that in activity from their you have to pass it to your fragment (replace fragment with your loginfragment)
