Insert-new-Contact-using-Android-App

Project functional specification: The app starts off with a main activity containing a welcome message and a button. Upon pressing the button, your app displays a second activity containing a one-line editor field, a button, and a read-only text view. The second activity allows the interactive user to enter the first and last names of a person in the editor field. When the button in his activity is pressed, your app switches to a different app for adding a new contact with the specified first and last name. This app could be the built-in Contacts app in the device, or a different app with similar functionality that the device’s user installed on the device. Now the device’s user has a chance to enter the new contact’s information. The contacts app must return automatically to your app when a user saves a new contact. Alternatively, the user may choose to return to your app without saving a new contact by pressing the “back” button. Either way, when your app resumes it will display a message in the read-only text field indicating whether the user had successfully saved the new contact or not.
