http://developer.android.com/training/basics/firstapp/creating-project.html.

Make sure you name the project as described on page 1 of this document.

Skip the steps that require the use of command line tools or real devices. This app allows the user to type a message in the text field and click Send button. The message will appear on the second activity as shown below.

Exercise 2:

Write an Android Application that demonstrates the activity life cycle and fragments.

• The main activity should have two fragments.

• The top fragment contains a list view control whose items are the names of two other activities, AIActivity and VRActivity.

• The bottom fragment uses a text view control to display the list of life cycle methods that take place when the main activity starts.

• Use Toast class methods to display a quick message in fragment’s onCreateView and onStart methods.

• The AIActivity and ARActivity should each have a TextView control to display messages when onCreate, onStart, onStop, and onDestroy are executed.

• Declare the String resources in strings.xml file. Feel free to use the code from SimpleFragmentsExample app from Week 1 examples.
