Try polling five, run the custom polling code on every version below lollipop, only retry when the error number was EINTR (interrupt - this is handled by the system itself above lollipop.)

Funny story, the advanced settings didn't work in release builds as some classes were missing in the release version (without ever crashing - smells like reflection). Somehow (even with minify enabled) this slipped trough in development.

For whatever reason I got crash reports that the server is null here (even though it can't possibly be)
