Proguard删除com.sun.mail.imap.IMAPProvider [英] Proguard removes com.sun.mail.imap.IMAPProvider

问题描述

在我的应用程序中，我将电子邮件发送到某个特定的地址，一切正常，但是当使用ProGuard进行混淆，缩小等操作时，它会失败

In my app I send emails to some specific address, it all works fine, but when it comes to obfuscation, shrinking, etc with ProGuard it fails

我尝试添加一些不起作用的ProGuard规则

I've tried adding some ProGuard rules, which didn't work

那是我的ProGuard

That's my ProGuard

-keepclassmembernames class com.sun.mail.imap
