You must submit two separate copies (one Word file and one PDF file) using the Assignment Template on Blackboard via the allocated folder. These files must not be in compressed format.

It is your responsibility to check and make sure that you have uploaded both the correct files.

Zero mark will be given if you try to bypass the SafeAssign (e.g. misspell words, remove spaces between words, hide characters, use different character sets or languages other than English or any kind of manipulation).

Email submission will not be accepted.

You are advised to make your work clear and well-presented. This includes filling your information on the cover page.

You must use this template, failing which will result in zero mark.

You MUST show all your work, and text must not be converted into an image, unless specified otherwise by the question.

Late submission will result in ZERO mark.

The work should be your own, copying from students or other resources will result in ZERO mark.

Use Times New Roman font for all your answers.

1-Question one

Please Open android studio and do the following: (you need to take screenshots of every steps that also authenticate your identity)

• Create a new Android project (use your name).
• Before you start, make sure to add constraint layout and make sure the Layout width and layout height is match parent. Also, make sure the Objects are work perfectly with each device.
• Add two buttons. Add text view includes this statement Welcome to Fun app .
• Assign unique IDs to each button and change the color for text view to red.
• In MainActivity.java, make each button display:
• Run the app using the Android Emulator.
• Write the Java code inside the onCreate() method here:

• A Toast message to the user (message should show your name and University ID).
• A Log message in Logcat (message should show your name and University ID).

2-Question Two

Explain how Java and Android work together to build and run Android applications and what is the difference between activity_main.xml and MainActivity.java?

In your answer, discuss:

• The role of Java in Android development
• The compilation process (Java code Bytecode Machine code)
• The role of Android Runtime (ART)
• What an APK file contains
• Difference between .xml and .java and how they work together.
• What is res folder and java folder?

Provide clear explanations of each stage of the execution process, your answer length should be reasonable, any very long answer will deduct your grade.

3-Question Three

There are many files and folders when creating a new project (such as manifests, java, res, and Gradle Scripts).

Note: Someone delete one of these files and folder.

• What challenges would developers face?
• How would the absence of the AndroidManifest.xml file affect an app?
• Why is calling super.onCreate() important in an Activity?
• How does the emulator improve development efficiency compared to testing directly on a physical device?
• In your opinion, which folder (manifests, java, res) is most important and why?

Try to support your answer with logical reasoning and answer for each question. your answer length should be reasonable, any very long answer will deduct your grade.
