Introduction


With an understanding of Fragments from the previous chapter, we're ready to expand on our discussion of widgets. In Chapter 3, Views, Widgets, and Styles, we discussed how to add widgets to your own app. Now, we'll look at how to create an App Widget so users can add your app on their Home screen.

The remaining recipes in this chapter will explore System UI options. There's a recipe for adding a Search option to the Action Bar using the Android SearchManager API. Another recipe will explore Full Screen mode and several additional variations on altering the System UI. The final recipe will showcase the new Lock Screen shortcuts introduced in Android O (API 26).
