is there a way to do "scale to fit" ?

I want an ipad app with background of 1024,768 (16:10) aspect to run on android with aspect of (16:9) for that i would like to scale to fit the screen so

1. the whole screen will be covered - no black stripes

2. i will continue to use the 1024,768 background as is no resizing (for scale outer) b/c the graphic elements on the edges are important to the game

so i dont mind if game will look a bit stretched on android as long as it runs, its fine.

Take a look at the following tutorial: https://www.scirra.com/tutorials/998/screen-resolution-for-mobile

And use the browser object

create a condition using on any touch, using the browser object to set to full screen.

like anything, you need to tested. Especially when you going to a tablet.
