我该如何解决这个错误？

Answer 1

正确的答案是,你的一些jar文件无法编译.您应该进入项目中的build.gradle文件,并查看依赖项.

如果您只是导入一些jar文件,您可以尝试删除它们并一次添加一个.这将帮助您确定哪一个导致错误.

在我的情况下,我做到了这一点,当我导入最后一个时,应用程序编译.所以我认为真正的问题是我一次导入的太多了.但现在一切正常.

Answer 2

在没有值得注意的变化之后,我突然遇到了同样的问题.

我通过删除app/build目录解决了它,让gradle构建整个项目new.

Answer 3

您必须检查是否再次导入相同的JAR.在我的情况下,罐子里面有一个类,它被导入另一个罐子里.所以只需检查整个项目中是否包含两次lib/class文件!
