I am creating an app which has main app and client app. In my app I want to add
Contact numbers. When I click on a contact second windows appears where I can input some details.
After that when I click send button the records should send to that phone number of client app.
I have attached the image of both screen.
As I am new to android, any one please help me what is the tech. used to achieve, and how to do this from scratch.
ie. how to add contacts on both sides, send records to client number etc. I am using SQL as my database
on both sides.
