如何解决？

推荐答案

出现此问题的原因是lib目录文件夹重命名为库现在Android的人。而只要我们把我们的外部罐这个库文件夹，然后它会自动被添加到应用程序的构建路径。

This issue occurs because the "lib" folder is renamed to "libs" now by Android People.And as soon as we place our external jars to this "libs" folder then it will automatically be added to the build path of the application.
