Implementing PreferenceActivity using ActionBarCompat. Add all these files to your project in a package name: android.support.v7.app In your PreferenceActivity extend ActionBarPreferenceActivity If you haven't started using ActionBarCompat and need to implement a PreferenceActivity, I advice you use ActionBarSherlock
