TvContract
class TvContract
kotlin.Any | |
↳ | android.media.tv.TvContract |
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.

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

- 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:

: 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"

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"
