Android Studio (Java) (XML)

Develop a contact management app (without persistency) called Contacts List:

- The app contains three activities and each activity must share the same header/toolbar display as the main activity which displays the applications name "Contacts List".

- The main activity would start with no contact but has a button where the user could click to add a new contact

- On clicking the button in the main activity, it goes to the second activity, where the user could add the contact information such as name, phone number, and email. After entering a new contacts information in the second activity, the user can then click a button labeled "Add To Contacts" to submit the information and then which causes the app to go back to the main activity

- When a contact is added, the main activity displays a list of contacts identified by the full name of each contact alphabetically. In the main activity, after a first contact has been added, a user should then be able to click each of the contacts names which then causes a third activity to open to display the selected contacts details that were added while using the second activity.
