}
return true;
}
}
我登录到预装的Facebook应用程序在我的设备我只有这个屏幕。
I logged in to preinstalled Facebook app in my device. And I got this screen only.
在我的Logcat中出现这一行。
And in my Logcat this line appears.
09-28 15:18:24.652: E/ActivityThread(1201): Failed to find provider info for com.facebook.katana.provider.AttributionIdProvider
如果我从我预装的Facebook应用程序中注销我的应用程序提示我登录，询问凭据。那个时候，空屏幕就出现了。但是在预装的Facebook应用程序中，我可以看到我的更新。（我已经登录）。
If I logged out from my preinstalled Facebook app, my application prompts me to login, asking the credentials. That time also, the empty screen appears.But in the preinstalled Facebook app, I can see my updates.( I get Logged in).
更新：
现在我正在检查该应用程序。我还没有发表到市场。参考这个网站 http ：//sean.lyn.ch/2011/07/android-the-facebook-sdk-sso-and-you/ 。我把它添加到应用程序，像这样。
Right now I'm checking the app only. I have not published it to market. I got the key by referring this site http://sean.lyn.ch/2011/07/android-the-facebook-sdk-sso-and-you/. And I added it to the app, like this.
更新2：
现在我在logcat中得到这些行：
Update 2: Now I got these lines in logcat:
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 com.android.internal.view.IInputMethodClient$Stub$Proxy@434b2e88 (uid=10031 pid=2233)
09-29 12:00:15.032: W/IInputConnectionWrapper(2233): showStatusIcon on inactive InputConnection

- 您没有提供正确的应用程式ID
- You are not connected to internet
- You have not given permission for internet access ( Manifest.xml)
