[Android] webview built-in Search dialog box

When you need to provide the search service in your application, where do you first think of your search box? By using the Android search framework, the application will display a Custom Search dialog box to process users' search requests. By using a simple search button or calling an API from your application, the Search dialog box is displayed at the top of the screen and your application icon is automatically displayed.

This article will teach you how to provide a Custom Search dialog box for your application. In this way, you can provide users with a standardized search experience and add functions such as voice search and search recommendations.
