Hi,
Just FYI:
For Native apps vibrator works for both cases (foreground and background).

vibration problem with notifications:

var notificationDict = {
    	              content : banner_content,
		              vibration : true, 
		              appControl : appControl,
		              appId : myappInfo.id,
		              iconPath : "/opt/apps/QUq5VDt2Zc/res/wgt/icon.png"};

why doesn't vibrate?

Vibration works, even when the web app is sent to background.

Have quickly tested with below code (20 secs vibration).

function singleVibration()
{
   /* Vibrate for 20 seconds */
   navigator.vibrate(20000);
}

On Samsung Gear 2 actual device, I tried background vibration and found it doesn't work, either.

Anyone know the solution?

Try turning screen on with tizen.power.turnScreenOn(); and then vibrate. Even try delaying time between screenon and vibrate.

Vibration in background is not possible but you can make app active by using alarm api.

My app has and alarm defined that, when triggered, turns screen on and do a long navigator.vibrate. Some users reports that vibration works only while screen is on. The screen turns off and vibration stops. The user turn on again the screen, and the app (that is not in backgraound!) starts vibrate again.

I never experienced this issue ... at least until I updated SDK. Now, in my Gear2Neo, I've got the same problem. How's it possible? Something has changed in SDK? But some users reported this issue months ago, when I compiled the app with the previous SDK.

Is there a way to keep the screen always on while vibration is active?

Thank you.

You can control screen state with tizen.power.request calls:

 

tizen.power.turnScreenOn(); //turn screen on
tizen.power.request("SCREEN", "SCREEN_DIM"); //keep the screen at least dimmed for undefinite time
tizen.power.request("SCREEN", "SCREEN_NORMAL"); //keep the screen at least in normal state
tizen.power.release("SCREEN"); //release screen state
