Hi~,

You may use code like below:

/*********************************************************
* [Step 1] Add the alarm privilege in config.xml
**********************************************************/
<?xml version="1.0" encoding="UTF-8"?>
<widget xmlns="http://www.w3.org/ns/widgets" 
    ...
    <TIZEN:PRIVILEGE name="http://tizen.org/privilege/alarm" />    
    ...
</widget>


/*********************************************************
* [Step 2] Add eventListener for timetick in the ambient mode
**********************************************************/
window.addEventListener('timetick', function() {
    // TODO : Update the ambient view    
    updateAmbientWatch(); 
}); 


/*********************************************************
* [Step 3] Add eventListener for ambientmodechanged
**********************************************************/
window.addEventListener('ambientmodechanged', function(e) { 
    if (e.detail.ambientMode === true) {        
        // TODO : Rendering ambient mode case         
        updateAmbientWatch(); 
    } else {             
        // TODO : Rendering normal case    
        updateNormalWatch(); 
        
        watchInterval = setInterval(function() { 
            updateNormalWatch();
        }, 1000); 
    }    
});

Hope it will help you.

Hi, thanks for answering Is the code is for detecting ambient mode? I'm looking for api that detect when watch is not on the wrist, maybe the system was using heart rate sensor for it? And I'm using native dev :)

You may use api for detecting motion sensor changed value or as you say heart rate sensor I think.

Thanks, I wondered how the default app did it, since it can detect when the watch is not in contact but there's no light appears from back

Combination of different indirect measure you may have this does, I think.
