PreviewProgram


public final class 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);
