Android GmailSender集成的Gradle错误

我正试着把这个和我的结合起来

我把所有的罐子都进口了。我可以毫无错误地重建项目。但当我尝试在手机上安装应用程序时，Gradle构建时，出现了280个错误。最后，我收到了消息BUILD SUCCESSFUL，应用程序在手机上正常运行（即使我没有收到邮件，但这是另一个问题）

这是我的Gradle控制台显示的内容：

    AGPBI: {"kind":"error","text":"warning: Ignoring InnerClasses     attribute for an anonymous inner class","sources":[{}]}
    AGPBI: {"kind":"error","text":"(com.sun.mail.imap.IMAPFolder$13) that doesn\u0027t come with an","sources":[{}]}

还有更多

但是当我在活动中删除sendmail（）方法时，错误就会消失

我希望有人能帮助我，提前谢谢你

对不起，如果我犯了一些英语错误

编辑：JavaMail包的更新修复了我的问题。

您正在使用的项目非常旧。您可能想试用的官方版本。@BillShannon我已经用您的软件包更新了软件包，它解决了我的问题。非常感谢。
