This chapter introduced Android’s new action bar view, a simplified bar that provides quick actions for Android applications. You learned about the options for adding navigation to your app, including the ViewPager, which is used extensively throughout the Android 4 release. The TimeTracker app has really come together now that you’re loading data from a database into the UI. In this chapter, you learned that

• The action bar replaces Android’s menu button and provides a unified look across applications.

• The action bar provides a simple tabbed browsing interface you can easily add to your app.

• The ViewPager class, available in the compatibility library, creates a paging-style interface.
