PreviewProgram

class PreviewProgram : BasePreviewProgram
androidx.tvprovider.media.tv.PreviewProgram

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

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

Usage example when inserting a preview program: 

PreviewProgram previewProgram = new PreviewProgram.Builder()
          .setChannelId(channel.getId())
          .setType(PreviewPrograms.TYPE_MOVIE)
          .setTitle("Program Title")
          .setDescription("Program Description")
          .setPosterArtUri(Uri.parse("http://example.com/poster_art.png"))
          // Set more attributes...
          .build();
  Uri previewProgramUri = getContentResolver().insert(PreviewPrograms.CONTENT_URI,
          previewProgram.toContentValues());

Usage example when retrieving a preview program: 

PreviewProgram previewProgram;
  try (Cursor cursor = resolver.query(previewProgramUri, null, null, null, null)) {
      if (cursor != null && cursor.getCount() != 0) {
          cursor.moveToNext();
          previewProgram = PreviewProgram.fromCursor(cursor);
      }
  }

Usage example when updating an existing preview program: 

PreviewProgram updatedProgram = new PreviewProgram.Builder(previewProgram)
          .setWeight(20)
          .build();
  getContentResolver().update(TvContractCompat.buildPreviewProgramUri(updatedProgram.getId()),
          updatedProgram.toContentValues(), null, null);

Usage example when deleting a preview program: 

getContentResolver().delete(TvContractCompat.buildPreviewProgramUri(existingProgram.getId()),
          null, null);
