How to use the media player in wd my cloud

Is there a widget for android phone and hoe to show album art work

My Samsung defaults to ‘Video Player’ which I think came pre-installed. But if you haven’t got any such players, then suggest a standalone media player with ability to source from a URL or DLNA/uPNP and point it towards your MyCloud device, works like a dream, particularly if you have various media file types that may not all work on your device (e.g. Avi doesn’t work through the mobile MYCloud on an Apple device, needs MPEG4).
