Objective

This assignment will help students integrate Google Maps SDK with Jetpack Compose, dynamically handle markers, fetch and update weather data for specific locations, manage local storage, and display routes using Google Maps. The app will consist of two main screens:

$1.$ Map Screen: Users can interact with the map, add markers, fetch and save weather data for specific locations.

$2.$ List Screen: Users can view saved locations with weather details and see routes to a selected location.

$3.$ Automated Weather Updates: Synchronize weather data for saved locations periodically using WorkManager.

Features and Implementations

$$

$1.$ Google Maps SDK:

$$ Integrate the Google Maps SDK with Jetpack Compose.

$$ Display a map in the app.

$$

$2.$ Markers and Weather Data:

$$ On a long$-$tap on the map:

$$ Add a marker dynamically at the tapped location.

$$ Fetch weather information for the tapped latitude and longitude using a weather API $($e$.$g$.,$ OpenWeatherMap API$).$

$$ Save the marker's latitude, longitude, and weather information $($e$.$g$.,$ temperature, condition$)$ to a local database $($Room$).$

$$ Show a toast or dialog displaying the fetched weather details after the marker is added.

$$

$3.$ Weather Data Sync Using WorkManager:

$$ Use the WorkManager API to periodically sync and update weather data for all saved locations in the local database.

$$ Weather updates should occur in the background even if the app is not open.

$$ Notify the user when new weather data is updated for any location using a system notification.

$$

$4.$ Local Database:

$$ Use Room to store:

$$ Marker details: latitude, longitude, and a custom name $($optional$).$

$$ Weather data: temperature, weather condition, and timestamp.

$$ Ensure data persists across app sessions.

$$

$5.$ List Screen:

$$ Retrieve saved marker data $($including weather details$)$ from the database and display it in a Compose LazyColumn.

$$ Display the marker$$s name, weather condition, temperature, and last updated timestamp in the list.

$$ On clicking an item:

$$ Navigate back to the map.

$$ Display a route from the user's current location to the selected marker location.

$$

$$

$$

$6.$ Route Display:

$$ Use Google Maps Directions API to calculate and show the route.

$$ Use the user$$s current location as the starting point and the selected marker as the destination.

$$ Draw the route on the map using a polyline.

$7.$ UI:

$$ Ensure the UI is clean and user$-$friendly.

$$ Use Material Design components for buttons, lists, and dialogs.
