Did you add Browser plugin, an event "On Suspended" ?
Yes Joannesalfa, i've added the Browser plugin with "On Suspended" event.

It works on Desktop browser and Android browser (tested on Chrome, Firefox Beta, Opera).
But when i'm compiled it with CocoonJS and make it native games (.APK), the game is not paused when my Android device in hold mode, and this plugin event "On Suspended" is not work as usual.
