Answer 1

If your activity does not have a title bar the method getActionBar() can return null.

You have two options to fix this:

1- Add getWindow().requestFeature(Window.FEATURE_ACTION_BAR); before setContentView

2- In your Manifest specify a Theme that supports ActionBar

Also make sure that you are targeting the right android version e.g. <uses-sdk android:minSdkVersion="11" />
