VI. Sample Exam Paper

Course: Mobile Application Development Technology (Practical)
Development Environment: JDK 1.8, Android Studio 4.1
Exam Duration: 90 minutes (note: syllabus says 120 min, sample says 90 min)

Task: Design a Body Weight Management Program.
The user enters name, gender, height, and weight, clicks “Calculate”, the app calculates BMI-related standard weight, then jumps to a second Activity to display advice.

Question 1: Android Project Creation and Configuration (30 points)

1. (5 points) Create an Android project named test + your candidate number.
2. (15 points) Add/modify resources:
   • Place provided images/resources into correct folders.
   • Add to colors.xml: <color name="skyblue">#87ceeb</color>
   • Modify strings.xml so the app title becomes your real name.
   • Add to styles.xml:

     <style name="CustomTitleFontStyle">
         <item name="android:textSize">16pt</item>
         <item name="android:textColor">#000000</item>
     </style>
     

3. (5 points) Create two Activities:
   • Launch Activity: Activity1.java with layout activity1.xml
   • Second Activity: Activity2.java with layout activity2.xml
4. (5 points) Add storage permissions to AndroidManifest.xml:

   <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
   <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
   

Question 2: UI Design (40 points)

Activity1.xml:

• (5 points) Choose appropriate layout(s) to achieve the interface.
• (20 points) Gender as horizontal RadioGroup (single selection only). Height and weight EditText with inputType=”number” and proper hints. Other controls as shown.
• (5 points) Background color = skyblue, title “Standard Weight Calculator” uses style CustomTitleFontStyle.

Activity2.xml:

• (10 points) Contains a TextView with id result.

Question 3: Functionality Implementation (30 points)

Activity1.java: On “Calculate” button click:

1. (5 points) Validate height and weight are within reasonable ranges (you define the range, perform necessary type conversion).
2. (10 points) Save input data to SharedPreferences file named mydata with keys:
   • name → your real name
   • gender → selected gender
   • height → entered height
   • weight → entered weight
     Export the generated mydata.xml file to your computer.
3. (5 points) Start Activity2 and pass gender, height, and weight via Intent extras.

Activity2.java: In onCreate():

• (10 points) Retrieve passed data, convert types as needed, calculate standard weight using:
  • Male: (height cm − 80) × 70%
  • Female: (height cm − 70) × 60%
• Display the result as a complete sentence in the TextView with id result.

Submission Requirements

1. Take full screenshots of both running screens (including title bar) and paste into a Word document named CandidateNumber.docx.
2. Export the SharedPreferences file mydata.xml.
3. Compress the following into a single file named CandidateNumber.rar:
   • The entire main folder of the project
   • CandidateNumber.docx
   • mydata.xml
