TvContractCompat

public final class TvContractCompat
extends Object

java.lang.Object
   ↳ 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 TvContractCompat.Channels and TvContractCompat.Programs tables.

  • A row in the TvContractCompat.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 TvContractCompat.Programs table represents a set of data describing a TV program such as program title and start time.
