当我使用Facebook的
Android SDK单点登录时,我得到一个完全无用的页面.
"You have already authorized app. Press "Okay" to continue.
此页面会破坏用户体验.如何删除此屏幕？
提前致谢.
注意：如果FB应用程序安装在设备中,我们将不会看到此问题.仅当FB应用程序在设备中不可用时才会引发此问题.
解决方法
我正在使用最新的Facebook SDK 3.6我相信并且已经在HTC One& amp; galaxy s3 mini.此页面在任何时候都不会显示给我.我在这里遵循API指南……
https://developers.facebook.com/docs/facebook-login
这是代码…也许这可能会有所帮助.
