Android ProGuard设置与使用许可服务器的应用程序一起使用不强制关闭？

Question

我似乎在互联网上的各种文章中尝试过各种设置，包括通过-keep public class排除我的所有课程。

应该使用哪些设置来强行关闭？在这一点上，如果我可以得到混淆，没有其他任何事情都没关系。

下面是我尝试过的示例配置，我的应用仍然强行关闭。任何想法？
我跟着这篇文章以及其他文章：http://android-developers.blogspot.com/2010/09/proguard-android-and-licensing-server.html

仍然没有运气。任何帮助，将不胜感激。 感谢

Answer 1

只需在proguard.cfg文件中注释这一行并清理/重建项目：

#-keep public class com.android.vending.licensing.ILicensingService

Answer 2

删除classes目录中的所有已编译类，并且重建是答案。有些东西显然是腐败的。一旦我这样做，它就行了！
