如果我通过在 project.properties 中注释掉“proguard.config=${sdk.dir}/tools/proguard...”禁用了 proguard，我的应用程序在调试以及导出到已签名的 apk 时也可以正常工作。

但是，如果我取消注释该行，我会收到一堆警告，并且 proguard 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.**

apk 将被创建，但不会在手机中执行。有趣的是，如果我删除这些行并使用“-dontshrink”，我会继续收到这些错误。我原以为这会解决这个问题。

我在http://developer.android.com/tools/help/proguard.html中发现我可能在我的配置中遗漏了一些 -keep 行，但这些行是什么并不明显。谁能提供线索？

默认的 proguard.cfg 文件试图涵盖一般情况，但您可能会遇到异常，例如 ClassNotFoundException，当 ProGuard 剥离应用程序调用的整个类时会发生这种情况。

当 ProGuard 剥离代码时，您可以通过在 proguard.cfg 文件中添加 -keep 行来修复错误。例如：

-保持公开课

Maybe a bit late, but searching for a solution to a similar problem, I learned that you have to tell proguard to keep some classes in your libs jars. Refer to the log where it says Warning: ... and can't find referenced class ....

So in your case should be:

-keep class javax.security.** { *; }
-keep class java.beans.** { *; }
-keep class java.awt.** { *; }

and

-libraryjars libs/XYZ.jar

for every jar into /libs containing those classes.
