android - Cordova - detect that app is in the background -

i have feature in cordova app lets user when user shakes phone (i'm using shake.js purpose). phone vibrates when happens.

the problem that, when "alt tab" away app , it's in background, shake/vibrate combo still works. user might using different app , phone still vibrate.

is there way detect app in background, or better yet, freeze app somehow when it's going background?

i have problem on android (haven't tested on ios yet).

you can bind pause event , remove shake feature app. according documentation (pause) event fires when application put background.

you can listen resume event put shake feature. usual in documentation can find complete code examples.
