Weather App Overview The Weather App provides real-time weather information for any city around the world. It fetches weather data from the OpenWeatherMap API and displays key details such as temperature, weather description, wind speed, pressure, humidity, sunrise, and sunset times. Users can input a city name to get the latest weather information for that location.
Features Real-Time Weather Data: Fetches and displays current weather information for a specified city. City Update: Allows users to enter and update the city name to retrieve weather data for different locations. Dynamic UI Updates: Updates the user interface with the latest weather data and handles errors gracefully. API Integration: Utilizes the OpenWeatherMap API to get weather details. Getting Started Prerequisites Android Studio or any compatible IDE Kotlin SDK OpenWeatherMap API Key Setup Clone the Repository
bash Copy code git clone https://github.com/yourusername/weather-app.git cd weather-app Add Your API Key
Open the MainActivity.kt file and replace the API variable value with your own OpenWeatherMap API key:
kotlin Copy code val API: String = "YOUR_API_KEY" Build and Run
Open the project in Android Studio, build the project, and run it on an emulator or physical device.
Usage Launch the App
The app will start with the default city set to Kapsabet, Kenya.
Update City
Enter the name of a city in the input field. Click the "Update City" button. The app will fetch and display weather information for the specified city. How It Works The app uses the OpenWeatherMap API to fetch weather data. Here's a brief overview of how the app works:
Fetch Weather Data
When the app starts or when the user updates the city, the fetchWeatherData function is called. This function sends an HTTP GET request to the OpenWeatherMap API endpoint with the city name and API key.
kotlin Copy code val response = URL("https://api.openweathermap.org/data/2.5/weather?q=$city&units=metric&appid=$API").readText(Charsets.UTF_8) Parse API Response
The response from the API is in JSON format. The updateUI function parses this JSON response to extract relevant weather information, such as temperature, weather description, wind speed, and more.
kotlin Copy code val jsonOb = JSONObject(response) val main = jsonOb.getJSONObject("main") val sys = jsonOb.getJSONObject("sys") val wind = jsonOb.getJSONObject("wind") val weather = jsonOb.getJSONArray("weather").getJSONObject(0) Update UI
The extracted data is then used to update the user interface elements in the app. The UI is updated with the weather details and any error messages if the request fails.
kotlin Copy code findViewById(R.id.address).text = address findViewById(R.id.update_at).text = updatedAtText Error Handling If there's an issue with fetching the weather data (e.g., network error or invalid city name), the app displays an appropriate error message to the user.
