PART 3 For part 3, you will develop a simple Android app that displays "Hello World". You will then add an additional "text area" and a "clickable button" as described in the Wei-Meng Lee textbook or other reference, Beginning Android Application Development.

To use Android Studio: 1. For information, go to: developer.android.com/tools/studio/index.html 2. To download, go to: developer.android.com/studio/index.html 3. Follow instructions to install Android Studio on your platform. 4. Develop your "Hello World" Android app by following the steps described at: hmkcode.com/android-studio-hello-world (similar instructions are available at other websites) 5. Use the procedure described in chapter 1 of the Lee textbook (or similar text) as a guide to add an additional text area and a clickable button (you will notice some minor differences between the Lee book instructions, and your project as generated by Android Studio). Note that Java JDK is needed to use Android Studio. Doing part 2 of this assignment first will ensure that JDK is properly installed on your computer. Obtain and keep paper copies or screenshots of the following: 1. Output of your HelloWorld application running on the Android emulator (page 19, figure 1-26). 2. Output of the emulator showing your HelloWorld application and other applications installed on the emulator (page 20, figure 1-28) Note the following while developing and running your HelloWorld application: 1) Use HelloWorld for your app name and xxxx.HelloWorld for your package name, where xxxx is your reverse email address (for example, edu.umich.kiumi.HelloWorld) 2) In part 3 of this assignment, it is not necessary for you to write any code. The IDE will generate your project. You only have to modify the main.xml file (or equivalent) as described in the textbook. 3) The main.xml file uses XML (similar to HTML) to define the user interface (UI) to your application. This user interface is called an Activity. An application can have zero or more activities. 4) It is a good idea to browse and look at all the files created by the IDE. Chapter 1 of the text book contains a description of most files. 5) If you are given a choice between "Android Project", "Android Sample Project", "Android Test Project" and similar, you should select "Android Project"
