Thanks for the links.
However, there doesn’t seem to be (and I may have missed it) a conclusive method for posting a Facebook text base message. One of the liked threads seems to have stopped at the point of trying to get it to work.
Also for Facebook, several tutorials (or thread links) speak about first creating an app on Facebook. Does this mean that each user of ‘my’ would have to do so, or that I can create ‘one’ app on Facebook and use this ‘one’ app (on Facebook) as the carrier for all other users who send their messages through the app (basic4android) that I am creating?
Basically, I am confused as to purposes of creating an app on Facebook.
