安卓+ Facebook连接不工作在发布版本

我有一个Android应用程序，允许用户连接到自己的Facebook账户，并自动做出他的墙后。

I have an Android application that allows the user to connect to his Facebook account and automatically make a post on his wall.

这一切都完美地工作与调试版本（使用备用的WebView对话框或本机应用程序活动）。我使用的是最新的Facebook连接API为Android。

All this is perfectly working with the debug build (using either the fallback webview dialog or the native application activity). I am using the latest Facebook Connect API for Android.

在测试应用程序的发布版本，我注意到，回退的WebView对话框不允许连接到Facebook（输入用户名/密码后，它显示了一个标准的404页，指出它无法找到该网页fbconnect： /成功/＃access_token = 3213546 ...）

When testing the release version of the application, I noticed that the fallback webview dialog does not allow to connect to Facebook (after entering the username/password, it shows a standard 404 page that says it could not find the page fbconnect:/success/#access_token=3213546...)

我怀疑的ProGuard已经剥离了一些code，但我无法弄清楚如何确定是什么原因造成的问题。任何人可以提供一些线索，让我在正确的方向？

I suspect proguard has stripped some code but I cannot figure out how to determine what is causing the problem. Could anybody give some clues and get me going in the right direction?

我的proguard.cfg文件包含以下行离开Facebook连接独自：

My proguard.cfg file contains the following lines to leave Facebook Connect alone:

-keep class com.facebook.android.*
-keepclassmembers public class com.facebook.android.Facebook { 
    public static final *; 
}

在usage.txt我能看到的Facebook类，串成员，...

In usage.txt I can see the facebook classes, string members, ...
