git clone https://github.com/ME-Massine/skycast.git
cd skycast

Open the folder and let Gradle sync.

Inside MainActivity.java, replace:

private final String API_KEY = "YOUR_API_KEY_HERE";

with your actual key from
https://openweathermap.org/api

Use an emulator or real device.
Make sure the device has Internet access.

GET /data/2.5/weather?q={city}&appid={API_KEY}&units=metric

GET /data/2.5/weather?lat={lat}&lon={lon}&appid={API_KEY}&units=metric

• User enters a city → Retrofit sends a GET request → JSON parsed into WeatherResponse → data displayed in UI.
• For location weather, app requests FINE_LOCATION permission, uses FusedLocationProviderClient to get last known location, then calls the coordinate API.
• Icons are fetched dynamically from OpenWeather’s icon CDN using Glide.
• Splash screen uses a timed navigation with fade animation.

• 5-day weather forecast (RecyclerView)
• Favorite cities saved with Room database
• Light / Dark mode toggle
• Lottie animated splash
• Offline caching
• Full MVVM architecture (ViewModel + LiveData)
• Settings screen (units: Celsius / Fahrenheit)
