You have to add the Android Support Appcompat V7 libraries to your compilation. Edit your build.gradle and put something like this in the dependencies section:

compile 'com.android.support:appcompat-v7:23.2.0'

The number 23.2.0 changes regularly. Android Studio is going to offer you the newest version in the tooltip.

In your project you use class ActionBarActivity , which is obsolete , it can only be used if you use the dependency of this latest version, but which is not recommended :

compile 'com.android.support:appcompat-v7:22.0.0'

The correct thing to do is to change to AppCompatActivity

The reason you get the message:

class file for android.support.v7.app.ActionBarActivity not found

is simply because it no longer exists in the latest versions of the support library.
