我正在尝试ColorMixer在PreferenceActivity. 这在部署到模拟器时以及在没有 proguard 的情况下导出时效果很好。但是当我在配置 proguard 的情况下导出它时，应用程序崩溃了。
我使用了最新的 Android SDK 附带的 proguard 配置。我添加了两行以至少可以看到代码“中断”的位置，并添加了两行以确保 proguard 使 CommonsWare 的内容保持不变。
-renamesourcefileattribute SourceFile
-keepattributes SourceFile,LineNumberTable
-keep class com.commonsware.** { *; }
-keep interface com.commonsware.** { *; }

ParcelHelper parcel=new ParcelHelper("cwac-colormixer", ctxt);
我将 CWAC-Parcel.jar 添加到 ColorMixer 项目，并将其添加到 Build Path。我根据需要在我的测试项目（包com.test）的构建路径上添加了 ColorMixer 项目
有谁知道我应该更改什么设置才能让它与 proguard 一起使用，因为我认为它与 ColorMixer 或 Parcel 无关。（因为它表明 ColorPreference 正在从 R 包中“请求”数据）
