SearchFragment

public class SearchFragment
extends Fragment

java.lang.Object
   ↳ android.app.Fragment
     ↳ android.support.v17.leanback.app.SearchFragment

This class was deprecated in API level 27.1.0.
use SearchSupportFragment

A fragment to handle searches. An application will supply an implementation of the SearchFragment.SearchResultProvider interface to handle the search and return an ObjectAdapter containing the results. The results are rendered into a RowsFragment, in the same way that they are in a BrowseFragment.

A SpeechRecognizer object will be created for which your application will need to declare android.permission.RECORD_AUDIO in AndroidManifest file. If app's target version is >= 23 and the device version is >= 23, a permission dialog will show first time using speech recognition. 0 will be used as requestCode in requestPermissions() call. setSpeechRecognitionCallback(SpeechRecognitionCallback) is deprecated.

Speech recognition is automatically started when fragment is created, but not when fragment is restored from an instance state. Activity may manually call startRecognition(), typically in onNewIntent().
