How do you start a SMS activity?

I can seem to find any example anywhere.
What are the two strings you need here?


I think it would be easier to use the Texting component from the Social category. The SendMessage method will launch the default SMS activity.

Unfortunately that does not work - it does nothing.

Show your blocks.


Hmmm, with companion app not working for me either:

(I tested with real phone number)

Sharing works though...


Try the u version of the companion app together with SendMessageDirect

That may well work, but doesn't resolve why SendMessage is not firing...
