Javascript Question

canvas animation stops playing when click homebutton (switch apps) on mobile device

I have problem with my canvas animation on my mobile device / tablet. Animation runs well until I click on "home" or "switchapp" button and then change the device "rotation". When I switch back to browser window with canvas animation, it is freezed and it won't play again.

Here is a fiddle: jsfiddle.net/nLmjchqv/

Is it possible to run animation again (like restart canvas)?
Is it possible to detect apps switch or home button click in JavaScript?

Thank you.


You can listen for the pageshow and pagehide Events (see MDN)

For example you can call cancelAnimationFrame on pagehide and then start the animation again with requestAnimationFrame on pageshow
