Designing Architecture for Real-Time Ride-Sharing App with Android and Web Dashboard

Follow these steps:

1. Build a backend API using Node.js or Django.
2. Choose a reliable database like PostgreSQL or MongoDB.
3. Implement secure authentication using JSON Web Tokens (JWT).
4. Use a real-time location tracking service like Google Maps or Mapbox SDK.
5. Handle ride requests by storing data in the database and notifying drivers via push notifications (e.g., FCM or APNS).
6. Manage drivers through endpoints for updating availability status and tracking earnings.
7. Create a web-based dashboard using React or Angular to communicate with the backend API.

Android Location Update:

LocationManager locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
LocationListener locationListener = new LocationListener() {
    public void onLocationChanged(Location location) {
        // Send location data to the backend API
        // ...
    }
};
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationListener);

Ride Request API:

app.post('/ride/request', (req, res) => {
    const rideRequest = req.body;
    // Store ride request in the database
    // ...
    // Notify nearby drivers via push notifications
    // ...
    res.status(200).json({ message: 'Ride request sent successfully' });
});

Driver Availability API:

app.put('/driver/availability', (req, res) => {
    const { driverId, isAvailable } = req.body;
    // Update driver availability status in the database
    // ...
    res.status(200).json({ message: 'Availability status updated successfully' });
});

Web Dashboard Code Snippets:

// Fetch driver earnings from the backend API
const fetchDriverEarnings = async (driverId) => {
    const response = await fetch(`/driver/earnings/${driverId}`);
    const data = await response.json();
    return data.earnings;
};

// Update driver availability status
const updateDriverAvailability = async (driverId, isAvailable) => {
    await fetch('/driver/availability', {
        method: 'PUT',
        headers: {
            'Content-Type': 'application/json'
        },
        body: JSON.stringify({ driverId, isAvailable })
    });
};
