PlayBook Accelerometer SDK

To those who have a device on-hand. Has anyone you been successful in trying to get the data from the accelerometer sensors?


Does anyone know the correct way to do it?


I've been trying on the device we have and have not had much luck... doesn't look like the AccelerometerEvent is even firing.


in my Main constructor I call --



this.addEventListener(AccelerometerEvent.UPDATE, onAccelerometerUpdateEvent);




And below is the event handler, I'm just updating a Label's text property with readings from the Update event.



private function onAccelerometerUpdateEvent(event:AccelerometerEvent) : void
  label.text = event.accelerationX + " -- " + event.accelerationY + " -- " + event.accelerationZ; 


But the label remains in it's initialized state .. i.e. "Hello World!"

I haven't looked at the APIs but if it is anything like on the phones, you have enable polling of the accelerometer for each app in order to be able to check it. The only things that can be check statically by default is the orientation.

Re: PlayBook Accelerometer SDK

THis is from the Tour De Flex Mobile project and it works on the Device I tested it. It reads out the values.

<?xml version="1.0" encoding="utf-8"?>
<s:VGroup xmlns:fx="http://ns.adobe.com/mxml/2009"

        import flash.sensors.Accelerometer;
    </fxSmiley Frustratedcript>
        if (Accelerometer.isSupported)
            var accelerometer:Accelerometer = new Accelerometer();
            accelerometer.addEventListener(AccelerometerEvent.UPDATE, function(event:AccelerometerEvent):void {
                l.text = "accelerationX = " + event.accelerationX +
                "\naccelerationY = " + event.accelerationY +
                "\naccelerationZ = " + event.accelerationZ +
                "\ntimestamp = " + event.timestamp;
            l.text = "Accelerometer not supported.";
    <s:Label id="l"/>

Re: PlayBook Accelerometer SDK

You need to add the event listener to an instance of the Accelerometer class, not to "this"...
