new Accelerometer(); instances an object from a PhoneGap classe.
So first, make sure you have all needed classes imported.
After that, put alerts at each step of the JS code with this syntax:
navigator.notification.alert("Alert Title", "Second title", "Alert Content");
for example:
> var axl = new Accelerometer();
>
> axl.watchAcceleration
> (
> function (Accel)
> {
navigator.notification.alert("Accel", "is updating", Accel.is_updating);
navigator.notification.alert("Threshold", "", threshold);
> if (true === Accel.is_updating)
> {
> return;
> }
this could brings you some visibility on what and where a bugfix is
needed in your code
