Class Overview

The TvInputService class represents a TV input or source such as HDMI or built-in tuner which provides pass-through video or broadcast TV programs.

Applications will not normally use this service themselves, instead relying on the standard interaction provided by TvView. Those implementing TV input services should normally do so by deriving from this class and providing their own session implementation based on TvInputService.Session. All TV input services must require that clients hold the BIND_TV_INPUT in order to interact with the service; if this permission is not specified in the manifest, the system will refuse to bind to that TV input service.

Summary

Nested Classes
class TvInputService.HardwareSession Base class for a TV input session which represents an external device connected to a hardware TV input. 
class TvInputService.Session Base class for derived classes to implement to provide a TV input session. 
Constants
String SERVICE_INTERFACE This is the interface name that a service implementing a TV input should say that it support -- that is, this is the action it uses for its intent filter.
String SERVICE_META_DATA Name under which a TvInputService component publishes information about itself.

Constants

public static final String SERVICE_INTERFACE

Added in API level 21

This is the interface name that a service implementing a TV input should say that it support -- that is, this is the action it uses for its intent filter. To be supported, the service must also require the BIND_TV_INPUT permission so that other applications cannot abuse it.

Constant Value: "android.media.tv.TvInputService"

public static final String SERVICE_META_DATA

Added in API level 21

Name under which a TvInputService component publishes information about itself. This meta-data must reference an XML resource containing an <tv-input> tag.

Constant Value: "android.media.tv.input"

Public Constructors

public TvInputService ()

Added in API level 21

Public Methods

public final IBinder onBind (Intent intent)

Added in API level 21

Return the communication channel to the service. May return null if clients can not bind to the service. The returned IBinder is usually for a complex interface that has been described using aidl.

Note that unlike other application components, calls on to the IBinder interface returned here may not happen on the main thread of the process. More information about the main thread can be found in Processes and Threads.

Parameters
intent The Intent that was used to bind to this service, as given to Context.bindService. Note that any extras that were included with the Intent at that point will not be seen here.
Returns
  • Return an IBinder through which clients can call on to the service.

public abstract TvInputService.Session onCreateSession (String inputId)

Added in API level 21

Returns a concrete implementation of TvInputService.Session.

May return null if this TV input service fails to create a session for some reason. If TV input represents an external device connected to a hardware TV input, TvInputService.HardwareSession should be returned.

Parameters
inputId The ID of the TV input associated with the session.
