Tizen app vibration background

Question

I have a Samsung Gear S and I'm bussy writing a web app. I would like to vibrate my app when I get a message from my server. I simply use navigator.vibrate(1000) and this works just fine. But when my app goes to the background the vibration doesn't work anymore. I've found this thread (https://developer.tizen.org/ko/forums/web-application-development/vibration-background?langswitch=ko) in which they face the same problem but there is no solution. Someone also suggested to use alarms to make your app active but I don't know how to do that. I suppose it is something like this:

var alarm = new tizen.AlarmRelative(1);
var service = navigator.vibrate(1000);
tizen.alarm.add(alarm, "org.tizen.browser", service);

This fails because the service isn't correct. How can I get this to work?

Answer 1

The following method:

You can turn on the screen light first then vibrate.

tizen.power.turnScreenOn();
navigator.vibrate(1000);

doesn't work quite yet. I had to add a delay for the vibration:

tizen.power.turnScreenOn();
setTimeout(function (){
    navigator.vibrate(1000);
}, 500);

EDIT: Also add from the other answers to the config.xml file,

<tizen:setting background-support="enable" background-vibration="enable" />
