How do I upload an image?

Please help me. I upload images to the screen using File Chooser:

Single click on the TEXT ---> Click action of File Chooser

Single click on the SPRITE ---> Upload an image from File Chooser.FileURLAt(0) in SPRITE

This works in the browser. But after replacing the clicks on the touch, and the assembly on android, the picture does not load. Nothing happens when you click on the TEXT. How can I fix this?

As far as I know, file chooser doesn't work on mobile.

Thanks for the answer! I think you are right! I hoped that somehow it is possible. Maybe there are other options in construct 3? I really need to export the image to a sprite in the apk application.
