Answer 1

You need to use appcompact from the Support Library.

Your activity needs to extend ActionBarActivity.

In your Activity

 public class MainActivity extends ActionBarActivity {

Import

 import android.support.v7.app.ActionBarActivity;

Instead of getActionBar() use getSupportActionbar()

Use Them.AppCompact

Or use ActionBarSherlock library.
