PreviewProgram

public final class PreviewProgram
extends Object

A convenience class to access TvContractCompat.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);
