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
