To use OkHttp you need to create a Request object. Makes sure to enable the use of the Internet permission in your AndroidManifest.xml fileĬreating request objects for make network calls Open adle and add the following dependency, or check the OKHttp site for the latest updates.Ĭompile '3:okhttp:3.8.1' It also is the underlying library for Retrofit library that provides type safety for consuming REST-based APIs.Īlso OKHttp supports both synchronous blocking calls and async calls with callbacks. OKHttp is built on top of the Okio library, which tries to be more efficient about reading and writing data than the standard Java I/O libraries by creating a shared memory pool. OKHttp removes the need for network testing, recovering from common connection problems, and on a connection failure, it can retry the request with a different route. OKHttp is an Android HTTP client library from Square that reduces the steps needed. Most apps need network connections to external services to access and exchange data. I won’t stop here too much, but you need to add the following instructions to adle: compile "3:okhttp:$okhttpVersion"Ĭompile "3:logging-interceptor:$okhttpVersion"Ĭompile (" to do GET and POST requests in Android using OkHttp Android If you’re interested in this, please let me know in the comments and I’ll write about it. We’ll see more in detail what are some of their differences, but you’ll see that everything is pretty easy and intuitive.Īnd we’ll also create some very useful extension functions, you’ll see.Īlso, Retrofit recently can be used in combination with Kotlin Coroutines. The code in Kotlin is going to be very similar to what we would use in Java.
If you want to start today, I recommend you take a look at my free training, where you will have an hour and a half of content to know what are your next steps to become an expert in Kotlin. You can see the full code working in the Bandhook Kotlin repository. Retrofit is a library that greatly simplifies doing requests to an API, and in this case I’m going to teach you how to integrate it with some LastFM API requests. This is just one more example about how in Kotlin we can continue to use the same libraries we’ve always used in Java for Android.
