flash.sensors.Accelerometer on Android within web browser

问题

The Accelerometer UPDATE event never fires, tho isSupported returns true, when the flash app is running inside the android web browser. How can I make it work?

     this.accelerometer = new Accelerometer();
            accelerometer.addEventListener(AccelerometerEvent.UPDATE, onAccelerometerUpdate);

My device is Samsung Galaxy S.

It does however work as an AIR app on android.

回答1:

You declared accelerometer as a local variable, so once it is out of scope it will no longer exist. Declaring the var as a class instance member ensures its existence until you no longer need it. http://forums.adobe.com/message/3363673#3363673

The fix was to declare the Accelerometer instance as a class member instead of a local variable.
