啓用proguard，我的構建版本的應用程序不會再安裝

Question

我啓用了proguard縮小我的版本apk。但是我的應用程序在那之後不會安裝。如果我得到一些關於如何修復它的幫助，請讓我很高興。它似乎無法找到我正在使用的應用程序主題引擎庫中的方法。

Answer 1

解決了它。我能夠找到一個工作解決方案閱讀：How to make Proguard ignore external libraries?。我加入了這個我ProGuard的文件：

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

最後一個是最imortant，它是整個主題化的圖書館，一些類找不到。
