I'm not sure if it's appropriate to post this here - so please forgive me if it's out of place!
For quite a few years now, I've maintained a little side project of mine, project blue. It's an audio-focused Android streaming application designed around JRiver's Media Center server, with the expressed goal of providing reliable audio streaming when on the go.
More than anything, it's a dogfooding project for me - circa 2012, I had the desire for an application that would stream reliably from Media Center without crashing or automatically closing (and as a bonus, can sync playlists), and while this field has certainly changed since then, I've still had a ton of fun maintaining the application. I just recently came back to this forum and discovered this "Remotes" board, and I thought I should let you fine folks know that it's out there for your use if you want it...
It's available on the Google Play store -
