Finally Open Whisper Systems has released Signal for Android which combines their older TextSecure (for encrypted messages) and RedPhone (for encrypted calls) apps into a single app.
It's also been available for iOS for a while.
The Android version can optionally be set to handle your texts, making the process a bit like iMessage where messages sent to contacts with Signal installed will be sent encrypted via the Internet, and those without will receive a plain old text message.
I've started the process of convincing my contacts to switch to it, and so far using the app has been a good experience. It currently lacks things like sticker packs and video chat so, if those are what you want from a messaging app, it may not be suitable for everyone.
