TvInputManager


class TvInputManager
kotlin.Any
   ↳ android.media.tv.TvInputManager

Central system API to the overall TV input framework (TIF) architecture, which arbitrates interaction between applications and the selected TV inputs.

There are three primary parties involved in the TV input framework (TIF) architecture:

  • The TV input manager as expressed by this class is the central point of the system that manages interaction between all other parts. It is expressed as the client-side API here which exists in each application context and communicates with a global system service that manages the interaction across all processes.
  • A TV input implemented by TvInputService represents an input source of TV, which can be a pass-through input such as HDMI, or a tuner input which provides broadcast TV programs. The system binds to the TV input per application’s request. on implementing TV inputs.
  • Applications talk to the TV input manager to list TV inputs and check their status. Once an application find the input to use, it uses TvView or TvRecordingClient for further interaction such as watching and recording broadcast TV programs.

ACTION_QUERY_CONTENT_RATING_SYSTEMS

Added in API level 21
static val ACTION_QUERY_CONTENT_RATING_SYSTEMS: String

Broadcast intent action used to query available content rating systems.

The TV input manager service locates available content rating systems by querying broadcast receivers that are registered for this action. An application can offer additional content rating systems to the user by declaring a suitable broadcast receiver in its manifest.

Here is an example broadcast receiver declaration that an application might include in its AndroidManifest.xml to advertise custom content rating systems. The meta-data specifies a resource that contains a description of each content rating system that is provided by the application.

<receiver android:name=".TvInputReceiver">
      <intent-filter>
          <action android:name=
                  "android.media.tv.action.QUERY_CONTENT_RATING_SYSTEMS" />
      </intent-filter>
      <meta-data
              android:name="android.media.tv.metadata.CONTENT_RATING_SYSTEMS"
              android:resource="@xml/tv_content_rating_systems" />
  </receiver>

In the above example, the @xml/tv_content_rating_systems resource refers to an XML resource whose root element is <rating-system-definitions> that contains zero or more <rating-system-definition> elements. Each <rating-system-definition> element specifies the ratings, sub-ratings and rating orders of a particular content rating system.

updateTvInputInfo

Added in API level 24
fun updateTvInputInfo(inputInfo: TvInputInfo): Unit

Updates the TvInputInfo for an existing TV input. A TV input service implementation may call this method to pass the application and system an up-to-date TvInputInfo object that describes itself.

The system automatically creates a TvInputInfo object for each TV input, based on the information collected from the AndroidManifest.xml, thus it is not necessary to call this method unless such information has changed dynamically. Use TvInputInfo.Builder to build a new TvInputInfo object.

Attempting to change information about a TV input that the calling package does not own does nothing.

Parameters
inputInfo TvInputInfo: The TvInputInfo object that contains new information. This value cannot be null.
Exceptions
java.lang.IllegalArgumentException if the argument is null.
