AppCompatActivity is the direct child class of FragmentActivity of support v4 and the direct parent class of ActionBarActivity .You can add an ActionBar to your activity when running on API level 7 or higher by extending this class for your activity and setting the activity theme to Theme.AppCompat or a similar theme.

Activity:by extending Activity you can avoid adding additional projects/libraries to your project but you'll lack the ActionBar on api levels below 11
