AppCompat library version 23 requires compileSdkVersion 23.

Also, ActionBarActivity is deprecated, use AppCompatActivity.

  1. Provide R.java file path in you import section

     import com.package.name.R;
  2. File-> Invalidate Caches/Restart

And also check targetSDK version in gradle.

To build your app, go to your app folder directory, in there there is a folder called .gradle, this folder is usually hidden so you have to find and delete it, then build your app again allow android studio to download the new .gradle contents for the app and hopefully you should not find the error again. To do this, you have to be connected to the internet.
