I’m trying to pass a List of items from one Activity to another but I keep getting this error:

no instance(s) of type variable(s) exist so that PlaylistItem conforms
to List

List<PlaylistItem> playlists = new ArrayList<>();

Intent intent = new Intent(this, MyApp.class);
Bundle bundle = new Bundle;
bundle.putSerializable("playlists", (Serializable) playlists);
intent.putExtras(bundle);
startActivity(intent);


public class MyApp extends Activity {
    protected void onCreate(Bundle savedInstanceState) {

        List<PlaylistItem> playlistItems = getIntent().getSerializableExtra("playlists", PlaylistItem.class); 

    }
}
