Im looking for a way to make a link between contact and Android Application. An example of this is Whatsapp, this application binds to a contact and makes it possible to launch the whatsapp application with the number as parameter. I have not been able to find a way of accomplishing this, and was wondering if there was someone with expierence in this area.
Your help is very much appreciated
