How do you import a package in Android Studio?

Question

I am extremely inexperienced with Android Studio - and am having an issue with my imports. I'm trying to build an app that creates music from an ArrayList of "note" objects (I've made this class - it has info on). I am trying to import midi driver (https://github.com/billthefarmer/mididriver) to play my music, but I keep getting an error when I try to write this:

import org.billthefarmer.mididriver;

in my code (specifically the Analyzer object I've made - you'll see it in the pic). Here is a pic of my project structure. I've added Midi Driver as a dependency to my build.gradle

implementation project(path: ':org.billthefarmer.mididriver')

in my app folder. I'm not sure what I'm doing wrong. I'm sorry to bother!

Here is the pic of my project structure

You appear to have two problems here each of which, by themselves, would cause the symptoms you describe.

First, as per the documentation for req.body:

Contains key-value pairs of data submitted in the request body. By default, it is undefined, and is populated when you use body-parsing middleware such as express.json() or express.urlencoded().

You don't seem to have loaded the JSON body-parsing middleware.

Second, you said mode: "no-cors" which tells fetch to silently ignore any attempts to do anything which would require permission from CORS.

This includes setting the Content-Type: application/json header which is needed to trigger the JSON parsing middleware.

So remove mode: "no-cors" and add the cors middleware to your server-side code.
