Errors with Android Studio

[Tarang]

I imported this project into Android studio but I run into a couple of errors, i'm not entirely certain its the part of the project but rather my clumsy usage

[glassactionbar] /Users/user/Downloads/GlassActionBar-master/glassactionbar/res/layout/gab__frame.xml:5: error: Error: No resource found that matches the given name (at 'layout_height' with value '?attr/actionBarSize').

[glassactionbar-sample] /Users/user/Downloads/GlassActionBar-master/glassactionbar-sample/res/values/styles.xml:3: error: Error retrieving parent for item: No resource found that matches the given name 'Widget.Sherlock.ActionBar'.

[glassactionbar-sample] /Users/user/Downloads/GlassActionBar-master/glassactionbar-sample/res/values/themes.xml:8: error: Error: No resource found that matches the given name: attr 'windowActionBarOverlay'.

There are a couple of others but they're along the same lines. Am I missing some file or is there a special way to import files into Android Studio? Is the ? from one of the errors from Unicode encoding or something?

Sorry for the late reply.

Looks like ActionBarSherlock is not properly added to your IntelliJ project. Add it as a library project and the errors should disappear.
