Canvas issues within a WebView in react native [pending]

Why changing the height > 100 and width > 640 on the canvas inside a WebView in react native, nothing else and drawing? 

//funciona 
...
canvas.width  = 640;
canvas.height = 100;
ctx.drawImage(img, 0, 0);
...

//não  funciona 
...
canvas.width  = 1024;
canvas.height = 768;
ctx.drawImage(img, 0, 0);
...

I was able to resolve by changing the dimensions at the end of the DOM load, as in the example below. 

window.onload = () => {
   canvas.width  = 1024;
   canvas.height = 768;
   ctx.drawImage(img, 0, 0);
   // ...
}

Turn level to Variable On android 8 the Service stops and does not restart when Activity quits
