Proguard和libgdx:RuntimeException

我正在使用libgdx开发一个
Android动态壁纸,当我使用proguard时,我遇到了一个大问题.这是我的livewallpaper启动时的错误:

这是我的proguard.cfg:

      void set*(***);

    }

   -keepclassmembers class *

-keep public class * implements cmn.Proguard$KeepMembers
-keepclassmembers class * implements cmn.Proguard$KeepMembers {

-keepattributes *Annotation*
-dontwarn android.webkit.JavascriptInterface

谢谢您的帮助!

最佳答案 我对AndroidInput类的混淆有类似的问题.它足以使用:

-keepnames class com.badlogic.gdx.backends.android.AndroidInput*
-keepclassmembers class com.badlogic.gdx.backends.android.AndroidInput* {<init>(...);}

…而不是没有人的回答,或者:

-keep class com.badlogic.gdx.backends.android.** { *; }

这是在libgdx:https://code.google.com/p/libgdx/issues/detail?id=1215的问题跟踪器中记录和回答的
