安卓+应用内BIlling +防护

Question

我已经创建了应用程序内绑定的应用程序，现在我想混淆我的代码，以缩短破解它的机会。BUt proguard设置有一些问题。我正在尝试通过this tutorial来设置它。我的项目结构是常见的，主项目有参考其他项目，其中有在应用程序服务的所有功能。我已经在最后一步停止了，这一步是使用代码混淆来执行ant release。所有的时间我都收到：

这个错误通知我没有找到一些东西，但是什么和如何修复它？

ANother的事情，当我在没有混淆的情况下发布未签名项目的第二步时，我收到了一些成功的通知：“看起来你有子项目，如果有，请使用--subprojects命令”。我尝试添加此参数，并收到完全成功，但没有很长时间，但我不能更新子项目。Im not sure it‘这是不是很糟糕。你能帮我把这个时刻也修好吗？

您正在使用的教程已过时。ProGuard现在是Android SDK的一部分。您可以按照Android SDK的documentation中的说明，在project.properties中的相应行中添加注释来启用它。
