Okay, to anybody who might stumble upon this now, Android Studio is very, very, very weird. Solution : Go to your build.gradle file and in your dependencies find the appcompat one, something like compile ‘com.android.support:appcompat-v7:XX.X.X’ Change it to compile ‘com.android.support:appcompat-v7:XX.X.+’ Then click on Sync Now on the top right of the editor.
