title: Android Support Library v7 missing appcompat
body: <p>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?</p>
  
  <p>Thanks</p>
