Question

我正在使用javamail API在我的应用中发送电子邮件和httpclient进行网络访问。我参考了演示gmailsender.Here是链接：Sending Email in Android using JavaMail API without using the default/built-in app

调试时没有错误，我可以在手机中顺利运行APK。但是，当我尝试使用proguard生成我签名的APK时，我发现控制台显示“Proguard返回错误代码1”，虽然我做了作为解决方案Android, javamail and proguard。因此，我无法使用Proguard构建我的APK。

有人可以帮我吗？控制台显示如下：

有关重复类的说明表明您在dexguard-project.txt文件中指定了-injars选项或-libraryjars选项。您不应该这样做，因为Android构建过程已经为您指定了所有必需的-injars，-outjars和-libraryjars。

如果您随后收到有关缺少课程的警告，您可以让ProGuard忽略它们，例如：

-dontwarn somepackage.SomeMissingClass
