如何避免在Android Facebook SDK中显示已经授权的应用程序对话框

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……

这是代码…也许这可能会有所帮助.
