How to make a request from an extension?

Extensions Extension Development
#1

Hi everyone,
I am trying to launch a GET request (later also a POST) from an extension I am making. I found this extension:

I decided to try and yeet some of the code used there but I am getting errors:

AndroidRuntime:

This is the request code:

@SimpleFunction(description = "Test")
    public void SendGetRequests(String url){
      RequestQueue queue= Volley.newRequestQueue(context);
      StringRequest stringRequest=new StringRequest(Request.Method.GET, url, new Response.Listener<String>() {
        @Override
        public void onResponse(String response) {
         Get(response);
  
        }
      }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
          Error(error.getMessage());
        }
      });
  
      queue.add(stringRequest);
    }

And those are my imports:

import com.google.appinventor.components.annotations.*;
import com.google.appinventor.components.runtime.*;
import com.google.appinventor.components.common.*;

import android.content.Context;
import com.android.volley.*;
import com.android.volley.toolbox.StringRequest;
import com.android.volley.toolbox.Volley;

import java.util.HashMap;
import java.util.Map;

And ideas how I can fix that? I don’t know where volley would be.

Would the page output the code needed? It sounds like it would just give blocks which is not what I need. In any case, thank you!

It can be used as Get method.

You can see the source of my baserow extension for some examples.

The source code you are using is missing the popular Android HTTP library Volley.
See examples here by Vknow to make a POST request:
