Channel

public final class Channel
extends Object

java.lang.Object
   ↳ android.support.media.tv.Channel


A convenience class to access TvContractCompat.Channels entries in the system content provider.

This class makes it easy to insert or retrieve a channel from the system content provider, which is defined in TvContractCompat.

Usage example when inserting a channel:

 Channel channel = new Channel.Builder()
         .setDisplayName("Channel Name")
         .setDescription("Channel description")
         .setType(Channels.TYPE_PREVIEW)
         // Set more attributes...
         .build();
 Uri channelUri = getContentResolver().insert(Channels.CONTENT_URI, channel.toContentValues());
 

Usage example when retrieving a channel:

 Channel channel;
 try (Cursor cursor = resolver.query(channelUri, null, null, null, null)) {
     if (cursor != null && cursor.getCount() != 0) {
         cursor.moveToNext();
         channel = Channel.fromCursor(cursor);
     }
 }
 

Usage example when updating an existing channel:

 Channel updatedChannel = new Channel.Builder(channel)
         .setDescription("New channel description")
         .build();
 getContentResolver().update(TvContractCompat.buildChannelUri(updatedChannel.getId()),
         updatedChannel.toContentValues(), null, null);
 

Usage example when deleting a channel:

 getContentResolver().delete(
         TvContractCompat.buildChannelUri(existingChannel.getId()), null, null);
