The answer to How to open Email program via Intents (but only an Email program) shows how to open a chooser with ONLY email programs displayed by calling intent.setType("message/rfc822").
I would like to do the exact same thing, but choose MMS capable (or even just SMS) instead of email programs.
The end goal is to create a "share with" chooser that sends different content depending upon the form the message will take. (Since an email can be a LOT longer than a text or a tweet, and can contain an video attachment.)
