Android - usage of back button

Guys,

Has anyone been able to use the Android back button to exit the game or minimize it.

I'm using crosswalk build and it doesnt seem like it works.

It would be nice to trigger a app close/minimize when user touches the android system's 'back' and people are kinda asking for it.

Same question but for a custom exit menu according to game design. I'm using Ludey for compiling.

Browser plugin should be all you need.

Thanks for your advice. If I trigger back button on android with the browser plugin, what command i must use for close game?

in browser plugin, there is also a close action which ends the game.

Google doesn't really want you closing your apps though. They prefer the user was able to just press the Home button and return to the app later at the exact same spot.

Thanks To all, great advices
