我使用下面的代码在我的应用程序中通过Facebook登录。我需要使用Facebook SSO来做到这一点。我有正确的app_id。Facebook SSO不能在android中工作

我登录到我的设备中预装的Facebook应用程序。我只有这个屏幕。 
而在我的Logcat中，此行出现。
09-28 15:18:24.652: E/ActivityThread(1201): Failed to find provider info for com.facebook.katana.provider.AttributionIdProvider
如果我从我的预装Facebook应用程序退出，我的应用程序会提示我登录，要求凭据。那时候，空白的屏幕也会出现。但是在预装的Facebook应用程序中，我可以看到我的更新（我已登录）。
更新：
现在我正在检查应用程序。我没有将它发布到市场上。我通过参考这个网站http://sean.lyn.ch/2011/07/android-the-facebook-sdk-sso-and-you/得到了钥匙。我将它添加到应用程序中，就像这样。 
更新2： 现在我得到了logcat的这些行：
09-29 12:00:12.552: I/ActivityManager(73): Starting activity: Intent { cmp=com.facebook.katana/.ProxyAuth (has extras) }
09-29 12:00:13.022: I/ActivityManager(73): Displayed activity com.facebook.katana/.ProxyAuth: 436 ms (total 436 ms)
09-29 12:00:15.032: W/InputManagerService(73): Starting input on non-focused client [email protected] (uid=10031 pid=2233)
09-29 12:00:15.032: W/IInputConnectionWrapper(2233): showStatusIcon on inactive InputConnection
CT hashkey你产生为您的应用正确和工作散列键？ –
是的。它工作正常，没有Sso。我需要实现sso。 – Manikandan
尽管您可能已经配置了哈希键，但它可能是错误的。要检查它，请参阅我的这个答案中的第二条评论：http://stackoverflow.com/a/10516629/450534。这是找到正确的哈希键AFAIK的最简单方法。并且大多数搜索结果对于该错误都提示相同的事情。不正确的哈希键。 –
