android-Search Overview

> Search is a core user feature on Android. Users should be able to search any data that is available to them, whether the content is located on the device or the Internet. To help create a consistent search experience for users, Android provides a search framework that helps you implement search for your application.

The search framework offers two modes of search input: a search dialog at the top of the screen or a search widget (SearchView) that you can embed in your activity layout. In either case, the Android system will assist your search implementation by delivering search queries to a specific activity that performs searchs. You can also enable either the search dialog or widget to provide search suggestions as the user types.
