On Android, the OpenKeychain app suits my needs just fine on the rare occasion I need to encrypt/decrypt on mobile, though I've never used its email integration... Apart from that I have basically the same workflow. I wrote a GUI program once to play with Clojure + Apache Pivot that lets me copy/paste text into the program's text fields and gives a dropdown of public keys (or an option to add a key), that's sometimes a bit more convenient. I can also explicitly manage whether I add myself as a recipient or not, lots of email clients seem to automatically encrypt to the sender's key as well so they can read it later.
