Easy Retrofit 2 Tutorial in Android Studio using Kotlin & Coroutines

Hey guys! So in this video I'll show you how to create this very basic app using Retrofit2, and hopefully that gives you a basic idea on how to use it. Otherwise in the near future I'll show you how to get a list of objects so you can create a nice app with a recycler view that takes data from the internet!

All you need for this app can be found down below:

Very good explained. There are a lot of 2-3 hours tutorials which contains a lot of irrelevant information combined with an incomplete example. Continue with that sir! I am a subscriber now, and have bookmarked some of your videos because those helps me in my everyday work

Thank you SIR for a very clear tutorial. It works and killed the headaches I had trying to figuring out how Retrofit works in other tutorials. Rainbow and cookies rain on you ^^

Thank you, I have learnt a lot from your videos!

I just noticed something that you wrapped the interface method returns with Call<>. But since you are using a version of Retrofit greater than 2.6.0, you can use the data class as the return type. For this to work, you would have to add the 'suspend' keyword before the fun methods in the api interface.

This will enable you to use coroutines automatically without worrying about the context changes as Retrofit is already configured to use a background worker thread for network calls.

Also that plugin is such a godsend, I was using jsonschema2pojo before, but this is much cleaner! :D
