![]() build(): Finally, we call the build() method to create the OkHttpClient instance with the configurations we specified in the builder. ![]() If you wanted to modify the request (for example, to add a header to every request), this would be the place to do it. This means that we are not modifying the request in any way before sending it. Val request = chain.request(): Inside the interceptor, we get the original request that was made.Ĭhain.proceed(request): We proceed with the original request. In this block, we define an interceptor using a lambda expression where we get the ongoing chain. Interceptors are used to monitor, rewrite, and retry calls. ![]() Let's start by implementing the required libraries in our app.gradle file dependencies ): Here, we are adding an interceptor to the OkHttpClient. Now that we have an overall understanding of what these two libraries do, let's start the implementation. Integration with RxJava: Retrofit can be integrated with RxJava, facilitating reactive programming and making it easier to handle asynchronous tasks and event-based programs.Ĭomplementary: OkHttp and Retrofit can work together, with Retrofit leveraging OkHttp for HTTP requests while providing a high-level, user-friendly interface for API interactions.Įfficiency and Performance: Using Retrofit with OkHttp combines the efficiency and performance of OkHttp with the ease of use of Retrofit, resulting in a powerful toolset for network operations in Android and Java applications.īest of Both Worlds: Developers get the best of both worlds: the low-level control of OkHttp and the high-level functionalities of Retrofit. Synchronous and Asynchronous Calls: Retrofit supports both synchronous and asynchronous network calls, allowing developers to choose the best approach for their needs. It is more about making it easier to connect to RESTful web services and APIs.Īnnotation-Based API Definitions: Retrofit allows developers to define APIs through annotations, which makes the code cleaner and easier to maintain.Īutomatic JSON Parsing: Retrofit can automatically parse JSON responses into Java objects using converters like Gson or Moshi, saving developers time and reducing boilerplate code. It is built on top of OkHttp and leverages OkHttp’s features. High-Level REST Client: Retrofit is a type-safe HTTP client for Android and Java. Manual JSON Parsing: If you are using OkHttp alone, you would have to manually parse JSON responses using a library like Gson or Moshi. WebSocket Support: OkHttp supports WebSocket communication, which facilitates real-time data exchange in a more efficient manner compared to HTTP polling. Interceptors: OkHttp supports interceptors, which can be used to monitor, rewrite, and retry calls. Request Customization: OkHttp allows for detailed customization of requests, including setting timeouts, adding headers, and more. It is more about handling the HTTP protocol, including connection pooling, caching, and handling requests and responses. Low-Level Networking Library: OkHttp is a low-level HTTP client used for sending and receiving HTTP requests and responses. OkHttp and Retrofit are both open-source tools used in Android and Java applications to handle network operations, but they serve slightly different purposes and can often be used together to complement each other. Create a new user (body of the request discussed later in the post)īefore we start the implementation, here's an overview of what exactly are these two libraries.
