启用proguard，我的构建版本的应用程序不会再安装

Question

我启用了proguard缩小我的版本apk。但是我的应用程序在那之后不会安装。如果我得到一些关于如何修复它的帮助，请让我很高兴。它似乎无法找到我正在使用的应用程序主题引擎库中的方法。

Answer 1

解决了它。我能够找到一个工作解决方案阅读：How to make Proguard ignore external libraries?。我加入了这个我ProGuard的文件：

-keep class javax.** { *; } 
-keep class org.** { *; } 
-keep class com.afollestad.** { *; } 

最后一个是最imortant，它是整个主题化的图书馆，一些类找不到。
