Working with APIs in android studio

[DarkDragon2K04]

I am a beginner with android app development and am working on a little project for a converter app. I want it to be able to convert currencies. So I have been hearing about APIs and was wondering if there was an API out there that could help me with this and how do I go around this. I am not asking for steps specifically for this but like a general tutorial on just how to use and implement APIs in android studio, maybe like a link to a tutorial or a step to step on how to do this generally so if I ever need to use APIs ever again I wouldn't need to bother anyone again.

Generally speaking an API is something that can receive and answer information requests. For instance a currency conversion API could take a couple of currencies as arguments and return the relative value - I'm pretty sure there are quite a few that do this. All you have to do as a developer is to send that request (usually by making an http request at a specially formatted address) and receive the answer (usually a http response), than use the data however you please.

 

The specifics of how to use the API depend on the service, they will most likely be explained in the documentation. Take a look at this for example.
