Description

In this video tutorial, we will continue the work on dialer app that we start in part-1. In this second and final part, we will use a contact picker that allows you to select any contact from your mobile contact list. We will use a logic to show this selected contact in our dialer app and we can now directly call on that Number.
We set up a back button that deletes one digit when you press it one time and we will set a logic to handle the error when no any number is in dialer and the user press the back button. We will use the segments concept for that.
