TvInputService.HardwareSession

public static abstract class TvInputService.HardwareSession
extends TvInputService.Session

java.lang.Object
↳	android.media.tv.TvInputService.Session
	↳	android.media.tv.TvInputService.HardwareSession

Base class for a TV input session which represents an external device connected to a hardware TV input.

This class is for an input which provides channels for the external set-top box to the application. Once a TV input returns an implementation of this class on onCreateSession(String), the framework will create a separate session for a hardware TV Input (e.g. HDMI 1) and forward the application's surface to the session so that the user can see the screen of the hardware TV Input when she tunes to a channel from this TV input. The implementation of this class is expected to change the channel of the external set-top box via a proprietary protocol when onTune(Uri) is requested by the application.

Note that this class is not for inputs for internal hardware like built-in tuner and HDMI 1.
