我刚刚完成了一个小型Android应用程序，我需要使用pro-guard来混淆任何私钥。我在项目（IDE Eclipse）中启用了pro-guard，但在导出时，它给了我以下错误（只是粘贴了一些错误）：

将这些行添加到proguard配置文件（proguard-android.txt）
-keep class android.support.v4.** { *; }
-dontwarn android.support.v4.**
-dontwarn javax.activation.**
-dontwarn javax.security.**
-dontwarn java.awt.**
-libraryjars <java.home>/lib/rt.jar
-keep class javax.** {*;}
-keep class com.sun.** {*;}
-keep class myjava.** {*;}
-keep class org.apache.harmony.** {*;}
-keep public class Mail {*;}
-dontshrink

我不了解OpenCSV库，但它看起来像是为标准Java而设计的。 Android Java是相同的编程语言，但不是相同的运行时环境。我在您的错误消息中看到对java.awt.datatransfer.Transferable和java.beans.PropertyEditor的引用。这些课程不存在于Android（full package list here）上。没有任何数量的Proguard配置会添加它们。您必须使用不同的CSV处理库，或至少剥离并解决您无法使用的OpenCSV部分。
