For a written blog tutorial you can visit this link:

You will need:

What is Retrofit?
------------------
Retrofit is a type-safe HTTP client for Android and Java. You can make network requests using Retrofit and it is used in android to call RESTful APIs.

Why Retrofit?
--------------
Though it is not necessary that you use a library like Retrofit for the network calls in your application. But if you will not use a library you have to take care of a lot of things, and it increases the task and amount of code.
Whereas Retrofit has predefined methods to quickly perform network requests. We also have other libraries in android for example volley, but if you are still using Volley for network operations then it is highly recommended that you should migrate to retrofit now. Retrofit is better than volley.

In this Retrofit Android Tutorial series we will learn a lot of things. We will learn
- Building RESTful API using SLIM framework
- Making the calls from our android app using Retrofit
- We will also learn deploying the REST API

To everyone getting this stupid Fatal error: Uncaught blah blah bullshit.

Simply change your code a little.
Right now, you all have this code:
$app->get('/hello/{name}', function (Request $request, Response $response, array $args) { ... }

Change it to full naming convention:
$app->get('/MyApi/public/hello/{name}', function (Request $request, Response $response, array $args) { .. }

Cheers!

Hello, do i need to install and create api project to every computer server?

My created api using the same tools is working fine on my laptop (server). When i copied the api project folder from my laptop and paste it to server’s directory on another computer, it is not working it says “cant find the file on this server” using postman.

I tried to install composer but the same things happened . I think i need to create api project on that computer then paste my php files to public folder. I wonder if it works.
