Android的支持库V7缺少应用程序兼容性 [英] Android Support Library v7 missing appcompat

问题描述

所以，当我导入Android的支持库V7（应用程序兼容性JAR），我看到我尝试使用它时，你得到一个noclassdeferror。这是因为android.support.v7.appcompat不被发现，因为它包甚至不是​​那里appCompat.JAR。我通过提取JAR文件中的内容确认这一点。我尝试重新安装与SDK管理器中的JAR，但是我每次都错过了同一个包。谁能告诉我这是怎么回事了？

So when I import the Android Support Library v7 (appcompat JAR), I see that I get a noclassdeferror when trying to use it. This is because the package android.support.v7.appcompat is not being found as it is not even there in appCompat.JAR. I confirmed this by extracting the contents of the JAR file. I tried reinstalling the JAR with SDK Manager, however I am missing the same package every time. Can someone tell me what's going wrong?

感谢
