我的应用程序在调试中工作正常，当我导出到已签名的apk时，如果我通过在project.properties中注释掉“proguard.config = $ {sdk.dir} / tools / proguard ...”来禁用proguard。
但是，如果我取消注释该行，我会得到一堆警告，而proguard将不会创建apk。我可以通过将以下行添加到proguard-project.txt
来抑制警告-dontwarn com.sun.mail.imap.protocol.**
-dontwarn org.apache.harmony.awt.**
-dontwarn javax.activation.**
并且将创建apk但它不会在手机中执行。有趣的是，如果我删除这些行并使用“-dontshrink”，我会继续发现这些错误。我本以为会解决这个问题。
我在http://developer.android.com/tools/help/proguard.html中发现我可能在配置中遗漏了一些保养线，但这些线路并不明显。任何人都可以提供线索吗？
默认的proguard.cfg文件试图涵盖一般情况，但是你 可能会遇到类似ClassNotFoundException的异常 当ProGuard剥离你的整个班级时，就会发生这种情况 应用程序调用。
当ProGuard通过添加a删除代码时，您可以修复错误 - proguard.cfg文件中的-keep行。例如：

也许有点晚了，但是在寻找类似问题的解决方案时，我了解到你必须告诉 proguard 在你的libs jar中保留一些类。请参阅日志Warning: ...和can't find referenced class ...。
所以在你的情况下应该是：
-keep class javax.security.** { *; }
-keep class java.beans.** { *; }
-keep class java.awt.** { *; }
和
-libraryjars libs/XYZ.jar
将每个jar放入包含这些类的/libs。
