why not just put a request into your favourite podcasting app?
Podkicker pro (https://play.google.com/store/apps/details?id=com.podkicker&hl=en_GB) uses the volume buttons and the play/pause button (if you have one)
:)
I just wanted it to be able to remember my subscriptions between ROMs. If I start listening to podcasts on my desktop also Ill look back into PocketCasts.
