首先它给出了无法解决 ActionBarActivity 的错误，我尝试通过添加外部 jar 来解决它们，然后出现了这些错误
最佳答案
删除工作空间中的 jar 文件即可解决问题
projectname>libs>android-support-v4
然后去
appcompat_v7>libs>android-support-v4
复制此文件并将其粘贴到您的项目中 此过程将帮助您绕过与此问题相关的所有错误
关于java - ActionBarActivity 无法解析为类型，Jar 不匹配 : Eclipse，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/26712932/
