I would like to develop an app for android and windows phone that calling button causes the application to run when the user press the dial/call button in his smartphone.
- Is it possible with windows phone? if yes, how?
- What is the function in Android that I can use with to push my app when the user press the call button.
- If someone know application that work that way, I would be very happy for some links for that kind of mobile apps you know.
