TvContractCompat

Kotlin |Java

class TvContractCompat

kotlin.Any
↳	androidx.tvprovider.media.tv.TvContractCompat

The contract between the TV provider and applications. Contains definitions for the supported URIs and columns.

Overview

TvContract defines a basic database of TV content metadata such as channel and program information. The information is stored in Channels and Programs tables.

• A row in the Channels table represents information about a TV channel. The data format can vary greatly from standard to standard or according to service provider, thus the columns here are mostly comprised of basic entities that are usually seen to users regardless of standard such as channel number and name.
• A row in the Programs table represents a set of data describing a TV program such as program title and start time.

Summary

	PreviewPrograms Column definitions for the preview TV programs table.

Constants

ACTION_INITIALIZE_PROGRAMS

static val ACTION_INITIALIZE_PROGRAMS: String

Broadcast Action: sent to the target TV input after it is first installed to notify the input to initialize its channels and programs to the system content provider.

Note that this intent is sent only on devices with android.content.pm.PackageManager#FEATURE_LEANBACK enabled. Besides that, in order to receive this intent, the target TV input must:

• Declare a broadcast receiver for this intent in its AndroidManifest.xml.
• Declare appropriate permissions to write channel and program data in its AndroidManifest.xml.

Value: "android.media.tv.action.INITIALIZE_PROGRAMS"

ACTION_PREVIEW_PROGRAM_ADDED_TO_WATCH_NEXT

static val ACTION_PREVIEW_PROGRAM_ADDED_TO_WATCH_NEXT: String

Broadcast Action: sent by the system to tell the target TV input that one of its existing preview programs is added to the watch next programs table by user.

The intent must contain the following bundle parameters:

• EXTRA_PREVIEW_PROGRAM_ID: the ID of the existing preview program.
• EXTRA_WATCH_NEXT_PROGRAM_ID: the ID of the new watch next program.

Value: "android.media.tv.action.PREVIEW_PROGRAM_ADDED_TO_WATCH_NEXT"

ACTION_PREVIEW_PROGRAM_BROWSABLE_DISABLED

static val ACTION_PREVIEW_PROGRAM_BROWSABLE_DISABLED: String

Broadcast Action: sent by the system to tell the target TV input that one of its preview program's browsable state is disabled, i.e., it will no longer be shown to users, which, for example, might be a result of users' interaction with UI. The input is expected to delete the preview program from the content provider.

The intent must contain the following bundle parameter:

• EXTRA_PREVIEW_PROGRAM_ID: the disabled preview program ID.

Value: "android.media.tv.action.PREVIEW_PROGRAM_BROWSABLE_DISABLED"

ACTION_REQUEST_CHANNEL_BROWSABLE

static val ACTION_REQUEST_CHANNEL_BROWSABLE: String

Activity Action: sent by an application telling the system to make the given channel browsable with user interaction. The system may show UI to ask user to approve the channel. This is only relevant to channels with Channels#TYPE_PREVIEW type. Use Activity#startActivityForResult to get the result of the request.

The intent must contain the following bundle parameters:

• EXTRA_CHANNEL_ID: ID for the Channels#TYPE_PREVIEW channel as a long integer.

Value: "android.media.tv.action.REQUEST_CHANNEL_BROWSABLE"

ACTION_WATCH_NEXT_PROGRAM_BROWSABLE_DISABLED

static val ACTION_WATCH_NEXT_PROGRAM_BROWSABLE_DISABLED: String

Broadcast Action: sent by the system to tell the target TV input that one of its "watch next" program's browsable state is disabled, i.e., it will no longer be shown to users, which, for example, might be a result of users' interaction with UI. The input is expected to delete the "watch next" program from the content provider.
