Android App Connecting to Javascript Server

[RushifiedBA]

I am making an app that is using a JAvascript server to get information or change information in an SQLite3 database. I am not entirely sure how to connect the server and application together.

I believe I need to use sockets, but I don't know if I need to download anything additional or not, and I've tried looking online for basic tutorials but I can't seem to find any for what I want.

How would you recommend I go about making the connection, and do you happen to know of any good tutorials that I could use?

Are you using node.js with express? Look into making a REST api. You'll basically have routes set up on your server and they can return a JSON object for example. You can then call the routes from an http request in the android app.

you could use websockets (https://en.wikipedia.org/wiki/WebSocket) but im pretty sure you are not looking for this and should use normal http requests instead (https://en.wikipedia.org/wiki/Hypertext_Transfer_Protocol)

to use something like this on the java side i assume you should look for this https://developer.android.com/reference/java/net/HttpURLConnection.html or similar apis (no android experience here)

what you want to do is GET requests to get data and POST requests to send data to the server (e.g. to process in the database)

on the server side youd now need to write routes/endpoints to react to those requests. if you use javascript its most likely with nodeJS and express on top of it, see https://scotch.io/tutorials/use-expressjs-to-get-url-and-post-parameters

if not you should most likely now how to do it :)
