Private constructor in DefaultMediaNotificationProvider makes overriding impossible

[tzugen]

Media3 Version

1.0.0-beta03

Reproduction steps

In getMediaButtons the comment reads:

Override this method to customize the buttons on the notification. Commands of the buttons returned by this method must be contained in MediaController.getAvailableCommands().

Unfortunately it seems to be impossible to extend DefaultMediaNotificationProvider in beta-3, because Java will require a call to the constructor() of the inherited function, but it is private in DefaultMediaNotificationProvider.

Maybe there is some advanced trick to get it working, but it shouldn't not be that complicated, or at least documented how one can do it.

Full code:

@UnstableApi public class CustomProvider extends DefaultMediaNotificationProvider {
    public CustomProvider(Context ctx) {
        super(new Builder(ctx));
    }
    
    @Override
    protected List<CommandButton> getMediaButtons(Player.Commands playerCommands, List<CommandButton> customLayout, boolean showPauseButton) {
        return super.getMediaButtons(playerCommands, customLayout, showPauseButton);
    }
}
