Building a weather application can be both an exciting and challenging project. In this guide, we will walk through how to create a simple weather app that fetches location data and displays the current forecast. No need to worry if you’re not a programming expert; this blog is designed to be user-friendly and informative.

Overview

Our weather app will utilize the OpenWeatherMap API. This API is perfect for small projects because it offers 1000 free API calls per day, multilanguage support, and alert capabilities for severe weather.

Prerequisites

Before diving into the code, ensure you have the following ready:

• An OpenWeatherMap API key. You can acquire one from the API Keys section.
• Your local.properties file should be updated with the following values:

OPEN_WEATHER_API_KEY=YOUR_KEY
OPEN_WEATHER_BASE_URL=https://api.openweathermap.org
OPEN_WEATHER_ICONS_URL=https://openweathermap.org/img/wn

Project Structure

Our project is organized into four main boundaries, creating a clean architecture pattern:

• Core: Contains models and data classes representing business logic.
• Data: Handles data sources for both local and remote data operations, using the repository pattern to manage state.
• DI (Dependency Injection): Connects core models and interfaces with the UI layer.
• UI: Includes presentation components and view models using the MVI design pattern for predictable state management.

Explaining the Code with an Analogy

Building a weather app is much like building a small restaurant:

• The Core layer acts like the recipe book; it holds the essential information needed to prepare dishes (data models).
• The Data layer is the pantry and ingredients section where you prepare and store food items (data storage and retrieval).
• DI is the kitchen staff that synchronizes the recipes and ingredients to ensure dishes are cooked as intended.
• The UI is the dining area where customers see the beautifully plated food and interact with the waitstaff (how users interact with your app).

Performance Monitoring

To ensure our app performs well, we can employ Firebase Performance and Crashlytics for monitoring. Additionally, LeakCanary can help identify memory leaks.

Troubleshooting

If you encounter issues while developing your weather app, consider the following troubleshooting tips:

• Ensure your API key is correctly added in the local.properties file.
• Check your internet connection when making API calls to avoid timeouts.
• If encountering data issues, debug the API responses to ensure they align with your application logic.
