解组时找不到类：com.google.android.gms.auth.firstparty.shared.PACLConfig

Question

我已经复制了这个示例应用程序https://github.com/googledrive/android-demos

我按照创建SHA1的所有说明，在Google developer console中正确设置。

我在使用 google play services 时遇到了一些问题（我认为它正在停止），为了解决它，我右键单击了 app > Android tools > Export Signed application package。

我安装在我的Samsung phone 中。当我启动它时，它要求我选择一个Gmail 帐户，我照做了。然后我从ListView中选择了Create a folder， 消息Signing in...This can take a few minutes 出现并且永远无法成功登录。差不多30多分钟了，还在继续。

我检查了Eclipse 中的Logcat，我有以下日志。 如何解决？

当您使用proguard 混淆您的代码时，请将以下异常添加到您的proguard file：

-keep class * extends java.util.ListResourceBundle {
    protected Object[][] getContents();
}

-keep public class com.google.android.gms.common.internal.safeparcel.SafeParcelable {
    public static final *** NULL;
}

-keepnames @com.google.android.gms.common.annotation.KeepName class *
-keepclassmembernames class * {
    @com.google.android.gms.common.annotation.KeepName *;
}

-keepnames class * implements android.os.Parcelable {
    public static final ** CREATOR;
}
