How to scale a pixi.js scene for different resolutions?

Question

Android

There was a need to create a single game client code for web and mobile. On the web, the client works correctly, but the apk built with cordova has problems with scaling.
The essence of the problem: on a 720x1280 device, the following code gives the scene dimensions 360x615, and the images added to the scene have a real size, and as a result, an image with a width of 480 pixels does not fit on a screen of 360 pixels, which should have a width of 720 pixels:

var renderer;
var stage;

window.onload = function() {
var w = screen.width;
var h = screen.height;


stage = new PIXI.Container();
renderer = PIXI.autoDetectRenderer(w, h);
document.body.appendChild(renderer.view);
}

Please suggest a good solution to this problem. Do I need to calculate the scale of all the elements that are on the stage myself?
