Covid-19 Tracer is an Android application designed to fetch and display COVID-19 data for various districts in India. The app retrieves data from a public API and presents it in a user-friendly format, helping users stay informed about the pandemic's impact in their region.

• Fetch COVID-19 Data: Retrieves real-time COVID-19 statistics (active, confirmed, deceased, and recovered cases) for districts in India.
• District-Level Data: Focuses on detailed district-wise information for better granularity.
• User-Friendly Interface: Displays data using a clean and simple ListView layout.
• Asynchronous Data Loading: Implements background tasks to fetch data without blocking the user interface.
• Error Handling: Provides feedback in case of data retrieval or parsing errors.

1. Clone the repository:

   git clone https://github.com/drish1001/Covid-19-Tracer.git

2. Open the project in Android Studio.
3. Sync Gradle files to download dependencies.
4. Build and run the app on an Android device or emulator.

The project uses the following dependencies:

• androidx.appcompat:appcompat:1.0.2
• androidx.constraintlayout:constraintlayout:1.1.3
• junit:junit:4.12
• androidx.test.ext:junit:1.1.0
• androidx.test.espresso:espresso-core:3.1.1

These are managed in the build.gradle file.

1. API Integration:

   • The app fetches data from the public API endpoint:

     https://api.covid19india.org/state_district_wise.json
     

   • The HttpHandler class handles HTTP requests and responses.

2. Data Parsing:

   • JSON data is parsed to extract district-wise statistics for a specific state (e.g., Rajasthan).
   • The MainActivity class processes this data and populates it into a list.

3. UI Display:

   • A ListView displays the parsed data using a custom layout (list_item.xml), showing details like active, confirmed, deceased, and recovered cases for each district.

4. Error Handling:

   • Displays appropriate messages if there are issues with API connectivity or JSON parsing.

The app requires the following permissions:

• Internet Access:

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

• Network State Access:

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

You can modify the app to fetch data for other states or customize its UI by editing:

1. API Endpoint: Update the URL in MainActivity.java.
2. UI Layouts: Modify XML files in the res/layout/ directory.
3. Themes and Colors: Customize colors in res/values/colors.xml and styles in res/values/styles.xml.

• The app currently focuses on Rajasthan's district-level data by default.
• No offline functionality; requires an active internet connection.
