Task Execution
1.UI Design
Layout Design:
Start by designing the user interface (UI) of your app. You’ll need fields for user input (e.g., weight and height), a calculate button, and a result display area to show the calculated BMI and health status.
2.BMI Calculation:
Logic Implementation:
Implement the BMI calculation logic. BMI is calculated as weight (in kilograms) divided by the square of height (in meters). Make sure to handle unit conversions if needed.
3.Health Status:
Categorization:
Categorize the BMI results into health statuses, such as underweight, normal weight, overweight, and obese. Determine the thresholds for each category and classify the user’s BMI accordingly.
4.Validation
Input Validation:
Ensure that user input is numeric and within reasonable bounds. Implement error handling to notify users if they enter invalid data.
5.Integration
App Integration:
Integrate the BMI calculation and health status determination into the UI. When users input their weight and height and press the calculate button, the app should display the BMI and corresponding health status.
6.Testing
App Testing:
Thoroughly test the app for accuracy and user-friendliness. Test various scenarios with different input values to ensure that the app produces correct results and provides meaningful feedback.
Deliverables
Your report should include the following:
1.A functional BMI calculator Android app.
2.A brief report describing the development process, challenges faced, and lessons learned.
Learning Outcomes:
By completing this task, you will gain the following skills and knowledge:
1.Android app development, including UI design.
2.Input validation and data processing in Android.
3.Implementing mathematical calculations and conditional logic.
4.Basic testing and debugging for Android apps.
Building a BMI calculator app is a practical way to apply your Android app development skills while addressing a health-related problem.
