JsonObjectRequest request get datafrom url work on virtual not o physical phone

Question

I'm just learning by trying create simple app in android studio (JAVA) :) I create code working on emulator(oreo). After build apk and instal it on phone (Nokia 8.1) it doesnt work. No errors while testing on emulator :/

Here is my code:

package com.stobolewski.jsonsavetest;

import androidx.appcompat.app.AppCompatActivity;

public class MainActivity extends AppCompatActivity {

    private List<String> menuOptions;
    private List<String> dataList;
    private String jasonDataFile= "";
    private TextView txtShowJSON;
    private Button btnDoAction;
    private Button btnClear;
    private Button btnLoad;

    private RequestQueue myJSONRequest;
    private String url = "http://brave-art.pl/news/data.jason";


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        txtShowJSON = (TextView) findViewById(R.id.txtShowJSON);
        menuOptions = new ArrayList();
        btnDoAction = (Button) findViewById(R.id.btnAction);
        btnClear = (Button) findViewById(R.id.btnClear);
        btnLoad = (Button) findViewById(R.id.btnLoad);
        myJSONRequest  = Volley.newRequestQueue(this);

        //jasonParse("menu");
        jasonParse();

        btnClear.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                txtShowJSON.setText("Clear text view...");
            }
        });

        btnLoad.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

                try {
                    String message;
                    FileInputStream fis = null;
                    fis = openFileInput("data.json");
                    InputStreamReader isr = new InputStreamReader(fis);
                    BufferedReader bufferedReader = new BufferedReader(isr);
                    StringBuffer stringBuffer = new StringBuffer();
                    while ((message = bufferedReader.readLine()) != null) {
                        stringBuffer.append(message + "\n");
                        txtShowJSON.setText("");
                        txtShowJSON.setText(stringBuffer.toString());
                        txtShowJSON.setVisibility(View.VISIBLE);
                    }
                }
                catch (Exception e){
                    e.printStackTrace();
                }



            }
        });

        btnDoAction.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

                String data = "";
                Log.i("INFO", "WE ARE HERE....");
                for(int i=0; i<menuOptions.size(); i++){
                    data += menuOptions.get(i) + "\n";
                }

                try {
                    Log.i("INFO", "WE ARE IN TRY ...");
                    //FileOutputStream output = new FileOutputStream("data.json", false);
                    FileOutputStream output = null;
                    output = openFileOutput("data.json", MODE_PRIVATE);

                    byte[] array = data.getBytes();
                    Log.i("INFO", "LOAD TO BYTE ARRAY...");
                    // Writes byte to the file
                    output.write(array);
                    Log.i("INFO:", "Data saved ...");
                    output.flush();
                    output.close();
                }

                    e.getStackTrace();
                }

                txtShowJSON.setText(data);
                Log.i("INFO", data);

            }
        });

    }

        });

        myJSONRequest.add(request);
    }

}

This is only way I can use "data from internet" my website hosting dowsnt allow to connect to database from "outside" - only local wordpress connection is allowed. Want to create simple app reading data "restaurant menu" from json file and show it in list view, etc.
