I'm trying to get my location coordinates with HTML5 but it gives me error every time .
this is the code I have write to phone gap android project
I used the same code on the documentation of the phone gap geolocation .
and add the call for the function device-ready () to know if this code is running
and it gives me
error 2 : messege 2 : the last location provider was disabled
this is the code that I'm using to get my location on the android device !

I got this tutorial from here http://docs.phonegap.com/en/1.7.0/cordova_geolocation_geolocation.md.html#Geolocation !
Hope to suggest what shall I do !!
Try setting the option enableHighAccuracy to true

I have created a phonegap app and I added Android platform to it. But unfortunately, deviceready event is not getting fired. It works fine on ripple emulator but it is not working on chrome (desktop) and on the android phone as well.
If I run it on chrome (desktop) or my Android L phone, I get the error gap:
["Device","getDeviceInfo","Device1231860141"]
and the browser as well as NetBeans hangs.
I have the cordova.js file in my www folder. I tried removing it, and the error goes away, but deviceready is still not fired.
The following is my code:
<!DOCTYPE html>

navigator.accelerometer.clearWatch(watchID);

deviceready is a cordova event it will not work in browser.
...
<script type="text/javascript">
document.addEventListener("deviceready", onDeviceReady, true);
function onDeviceReady() {
startWatch();
}
...
</script>
</head>
<body onload="onDeviceReady()">
</body>
</html>
Let me first start by saying that I have seen a lot of these questions, and many of them just says it <script src="cordova-x-x-x.js"></script> and some says not include the cordova.js file into Phonegap Build.
So I have been testing and fixing my code for some time now, and still getting the error from onError function. I have also copied and pasted the code from phonegap docs.
So here's the clean code from the url:
<!DOCTYPE html>
<html>
<head>
<title>Acceleration Example</title>
<script type="text/javascript" charset="utf-8" src="cordova.js"></script>
<script type="text/javascript" charset="utf-8">
document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady() {
navigator.accelerometer.getCurrentAcceleration(onSuccess, onError);
}
function onSuccess(acceleration) {
alert('Acceleration X: ' + acceleration.x + '\n' +
'Acceleration Y: ' + acceleration.y + '\n' +
'Acceleration Z: ' + acceleration.z + '\n' +
'Timestamp: ' + acceleration.timestamp + '\n');
}
function onError() {
alert('onError!');
}
</script>
</head>
<body>
</body>
</html>
And in my config.xml file I have added:
<gap:plugin name="org.apache.cordova.device-motion" />
<gap:plugin name="org.apache.cordova.device-orientation" />
After testing and asking the Phonegap Build crew, they showed me a code with all the functions. And this is the best way to get the accelerometer to work with Phonegap Build

I would say you try a total clean reinstall/rebuild with cordova. First off all you have to install cordova for that. If you want to know, how to get started with that you should have a look into the cordova documentation: Cordova CLI-Docs
After you installed cordova, you enter the Terminal and type in the following commands:
cd ~/desktop
cordova create test com.example.test test
cd test
cordova platform add android
cordova plugin add org.apache.cordova.device-motion
cordova build
Open the builded project in Eclipse and add

Save all and deploy the project to your device. And let me know, if this worked or not.
Can't comment, so answering instead.
In reference to above comment re "Phonegap and Cordova are similar (Same codebase)"
From http://docs.build.phonegap.com/en_US/3.1.0/introduction_getting_started.md.html:
To do so, simply ensure that the following reference is made in your
index.html
<script src="phonegap.js">
Note that this is interchangeable with
<script src="cordova.js">
I have a problem concerning the geolocation function in my android app and used the code below to test this default functionality (copied 1:1 from the phonegap website), but somehow can't get it to work.
When I build the android app the geolocation function does absolutely nothing, not an error, nothing. However when I test it in a browser everything works and a location is retrieved. All location services on the phone are turned on, when I turn them off, I do get the appropriate error message.
When I test the geolocation functionality in the phone's browser it does work.
I am testing on the Galaxy Nexus (android 4)
Dreamweaver CS 5.5 (updated today)
Latest Android sdk (updated today)
Manifest file is default, everything is permitted
Can somebody please help me out, I am starting to become really desperate as I can’t get this standard code to work.

this is my code:
function onDeviceReady() {
console.log("Device Ready");
startWatch();
};
function startWatch() {
// Update acceleration every 5 seconds
var options = { frequency: 5000 };
watchID = navigator.accelerometer.watchAcceleration(onSuccess, onError, options);
};
function onSuccess(acceleration){
console.log('Acceleration X: ' + acceleration.x +
'Acceleration Y: ' + acceleration.y +
'Acceleration Z: ' + acceleration.z +
'Timestamp: ' + acceleration.timestamp);
};
function onError(){
console.log("Acceleration Error occured");
};
I test it on 2 Android Phones (Samsung Galaxy Nexus GT-I9250, Android 4.0 and Huawei Ideos X3, Android 2.3.3), from my console outputs I know both only call the Error Callback, but why?
I can't find the cause for this on google, so please help if you have an Idea.
You might have a timing issue.
You should try the following which runs successfully on my HTC Evo or post your whole app:

Could it be because you are passing in a reference that does not exist to your watchAccelerometer() call?
You are passing in onError, but the name of your handler is accelerometerError
Here is a thought. I have not tested this (my Mobile Dev machine is at home), but it occurs to me that you may need to tell Android devices that you want to use the accelerometer in your Android Manifest.
<uses-feature android:name="android.hardware.sensor.accelerometer" android:required="true" />
Do you have that setting in your manifest XML file?
I'm trying to work out the watch position with android but its not working!!
<script type="text/javascript" charset="utf-8" src="phonegap.js"></script>
<script type="text/javascript" charset="utf-8">
// Wait for PhoneGap to load
//
document.addEventListener("deviceready", onDeviceReady, false);
// PhoneGap is ready
//
function onDeviceReady()
{
watchID = navigator.geolocation.watchPosition(onSuccess, onError,{enableHighAccuracy: true,frequency: 3000 });
}
// onSuccess Geolocation
//
function onSuccess(position)
{
alert("Successful!!");
}
// onError Callback receives a PositionError object
//
function onError(error) {
alert('code: ' + error.code + '\n' +
'message: ' + error.message + '\n');
}
</script>
Check the path to phonegap.js. When I changed your snippet to match the phonegap-1.1.0.js in my assets/www directory, the Successful!! alert popped up for me.
