Learn to integrate RESTful web services into Android applications using Retrofit, one of the most popular HTTP communication libraries for Android development. Master the fundamental concepts of HTTP and RESTful web services while building practical skills to connect your apps to remote servers for data sharing, third-party service integration, and server-side data persistence. Discover how to set up Retrofit with GSON in your Android projects and create web service interfaces using Kotlin. Practice making various HTTP requests including GET, POST, PUT, and DELETE operations while implementing proper error handling and response management. Explore advanced techniques such as using path parameters, query parameters, and query maps to fetch specific data from servers. Learn to add HTTP headers to requests, create custom interceptors for application-wide modifications, and handle request timeouts for slow network connections. Gain hands-on experience with logging interceptors to monitor HTTP requests and responses, and understand how to cancel HTTP requests when needed. Build a complete sample application called GloboFly that demonstrates the transition from local data management to web service integration, covering essential HTTP tasks and modern Android development practices for connected applications.
