Hi,

I'm trying to get a sample app running using the cordova compass, but each time the error callback is called with error code 3.

Here is the code:

<!DOCTYPE html>

<html>

<head>

<title>Compass Example</title>

<script type="text/javascript" charset="utf-8" src="cordova.js"></script>

<script type="text/javascript" charset="utf-8">

// The watch id references the current `watchHeading`

var gWatchID = null;

// Wait for device API libraries to load

document.addEventListener("deviceready", onDeviceReady, false);

// device APIs are available

function onDeviceReady() {

startWatch();

}

// Start watching the compass

function startWatch() {

// Update compass every 3 seconds

var options = { frequency: 3000 };

if (!gWatchID)

gWatchID = navigator.compass.watchHeading(onSuccess, onError, options);

}

// Stop watching the compass

function stopWatch() {

if (gWatchID) {

navigator.compass.clearWatch(watchID);

gWatchID = null;

}

// onSuccess: Get the current heading

function onSuccess(heading) {

var element = document.getElementById('heading');

element.innerHTML = 'Heading: ' + heading.magneticHeading;

}

// onError: Failed to get the heading

function onError(compassError) {

alert('Compass error: ' + compassError.code);

}

</script>

</head>

<body>

<div id="heading">Waiting for heading...</div>

<button onclick="startWatch();">Start Watching</button>

<button onclick="stopWatch();">Stop Watching</button>

</body>

</html>

So far I've:
- created a new cordova app:
cordova create compassDemo com.example.compassDemo "compassDemo"
- added the android platform
cordova platform add android
- added the device-orientation plugin
cordova plugin add org.apache.cordova.device-orientation
- copied the code above as index.html to the www folder (all other files within this folder were deleted previously)
- built the app
cordova build android
- and started the app
cordova run android

The app is built, deployed and started successfully, but only

According to the documentation only two error code are definded:
CompassError.COMPASS_INTERNAL_ERR = 0;
CompassError.COMPASS_NOT_SUPPORTED = 20;

So I wonder what's the meaning error code 3?
And what am I doing wrong?

I suppose there's something wrong with the configuration, but I have no clue what!?

I've also tried other plugins like accelerator and geo location, but none of them worked.
(fyi I'm using cordova 4.0.0)

Thanks for your help,
Michael
