i have a app where user click a button and then i want to show the phone's default contact list and then user will select the name/number and it will return the selected name/number. back in the days of windows mobile it was very easy, i dont know if there is a library/class for it.
No, by selecting contact i mean. display the phone's contact dialog and get the contact (name and no) the user selected. Eg-like opening the camera dialog and taken a pic and then returning back to our app.
