Android Studio Lab Assignment - Habit Tracker App

Objective

To design and implement a multi-screen Android application using Android Studio. The app serves as a Habit Tracker, allowing users to monitor their habits and track progress through user inputs and visual feedback.

Lab Tasks

1. App Design and Development

  • Developed a Habit Tracker app with the following features:
    • Screen 1: Introductory screen with a welcome message and a button to navigate to the tracker screen.
    • Screen 2: Functional screen for habit tracking, including:
      • Input fields for habit name.
      • Radio buttons for selecting tracking frequency (daily/weekly).
      • A seek bar for progress tracking.
      • A "Mark as Complete" button to update progress.
    • Integrated Text-to-Speech (TTS) functionality to provide auditory feedback.

2. Input Types Used

The app incorporates the following input types:

  1. EditText: For entering the habit name.
  2. RadioButtons: To select tracking frequency (daily or weekly).
  3. SeekBar: For visual representation of progress.
  4. Button: To navigate between screens and submit inputs.
  5. Text-to-Speech (TTS): To provide auditory feedback upon completing a habit.

3. App Functionality

  • Screen Navigation:
    • Used Intents to navigate between the welcome screen and the tracker screen.
  • Habit Tracking:
    • Users can input their habit name and select a tracking frequency.
    • Progress is tracked using a seek bar and updated dynamically.
  • Text-to-Speech Feedback:
    • When a habit is completed, the app provides encouraging auditory feedback.
  • Progress Calculation:
    • The app calculates progress based on user input and displays it visually and as text.

4. Challenges Faced

  • RadioButton Behavior:
    • Struggled with making radio buttons dynamic for toggle selection.
  • Initial Environment Setup:
    • Found Android Studio overwhelming initially but became more comfortable as the project progressed.

What I Did

  1. Setup and Navigation:
    • Set up Android Studio and installed an external emulator (BlueStacks) for testing.
    • Designed the app layout using XML for two screens.
    • Implemented Intents to enable smooth navigation between screens.
  2. Implemented Functionalities:
    • Added user input fields, progress tracking, and TTS feedback.
    • Wrote logic for progress calculation and habit completion.
  3. Debugging and Testing:
    • Tested the app on the Android Studio emulator and external emulator.
    • Debugged issues with RadioButtons and ensured the app was stable.

Reflection

This assignment was a great learning opportunity. Initially, Android Studio was overwhelming with its extensive features and tools. However, as I progressed, I became more comfortable with the environment. Implementing features such as user inputs, progress tracking, and Text-to-Speech was fascinating, as they are commonly used in daily apps.

Challenges like managing RadioButton behavior for toggle selection were frustrating but provided valuable insights into debugging and problem-solving. This project gave me a good understanding of the effort required to build functional and user-friendly apps. Overall, I feel more confident using Android Studio compared to my first project.
