In your build.gradle add following line under dependencies block:

compile 'com.android.support:appcompat-v7:21.0.+'

Also make sure to have compileSdkVersion and targetSdkVersion set to 21 under android block.

Then Sync your project. If autoimport is disabled - add this import:

import android.support.v7.app.ActionBarActivity;

Also update Android Studio and gradle plugin to the latest version.
