This project will help you practice the skills and concepts you learned related to structs and classes in Java. For this project you'll build an app that is a basic contacts manager app. It will allow you to save and view contact information for your friends.

1. Create a new Android Studio project
2. Name the project "Friends"

1. Open the app's activity_main.xml file.
2. Add two edit text fields to the main screen.
3. Add a button to the main screen
4. Make the button's text "Create Contact"
5. Add a scroll view with a linear layout child to the screen.

1. Create an even listener for the button in MainActivity.java
2. Create data members for all other widgets MainActivity.java

1. Create a new file called "Contact.java"
2. Create a class called Contact
3. Add String name and String phoneNumber properties.
4. Write an constructor that takes name and phoneNumber as arguments and initializes the corresponding properties using this. syntax.

1. Create a new file called "ContactsManager.java"
2. Create a class called ContactsManager
3. It should contain a variable array property called contacts whose type is an ArrayList of Contact objects
4. Add a method called Contact createContact(String name, String phoneNumber). It should create a new instance of Contact, and add it to the contacts ArrayList.
5. In MainActivity.java, add a data member called contactsManager instantiate and assign an instance of ContactsManager to it (ContactsManager contactsManager = new ContactsManager())

1. In the action for the "Create Contact" button, get the strings entered in the text field.
2. Use these strings to call the contacts manager's createContact() method.
3. Write a method that will generate and return a TextView that accepts a String as the text value.
4. Refresh the the text view by adding the new contact as a new text view to your linear layout view.
5. Every contact from the array should be in this list

1. Build and run your app using the your preferred testing environment.
2. Enter various contacts making sure that they text view shows each contact you create.

If you finish and want another challenge try adding the ability to delete contacts.

TIP: You'll have to find a way to identify which contact to delete. The "TAG" attribute allows you to attach hidden information to the UI element. This could be used to add a unique id that would then be matched in the Contact class to ensure that the correct contact is deleted.
