phonegap android app for google map geolocatin issue - android

I am making phonegap android application for geolocation. But it doesn't show google map.My code is as follow. I installed geolocation plugin for cordova. And it run proper upto alert of geocode in below code. I am testing with android mobile.

How to show a Google map in your Phonegap app using Google Map api V3?
Start by adding a reference to Google maps api in index.html:
<script src="http://maps.googleapis.com/maps/api/js?sensor=false"></script>
<link href="http://code.google.com/apis/maps/documentation/javascript/examples/default.css" rel="stylesheet" type="text/css" />
Then add a div that will contain the map. Choose an id like “map_canvas”. That id will be used to add our map from our javascript later on.
<div id="map_canvas">
</div>
2. Create a new javascript file called googlemap.js in the www folder and add the following content:
function GoogleMap(){
this.initialize = function(){
var map = showMap();
}
var showMap = function(){
var mapOptions = {
zoom: 4,
center: new google.maps.LatLng(-33, 151),
mapTypeId: google.maps.MapTypeId.ROADMAP
}
var map = new google.maps.Map(document.getElementById("map_canvas"), mapOptions);
return map;
}
}
and add a reference to it in index.html
<script type="text/javascript" src="googlemap.js"></script>
the mapOptions variable contains information about zoomlevel, where the center of the map is and what kind of map we want to show.
And the line containing the map variable uses getElementById to get our map_canvas and adding the map.
3. Showing the map
To show the map we must run the initialize function in googlemap.js. Since we are using the example index.html from phonegap we add these lines to the onDeviceReady function in index.html
function onDeviceReady(){
var map = new GoogleMap();
map.initialize();
}
Now run the app and you should se a map over Australia.
4. Adding markers
To add markers to our map we use the LatLng and Marker object from Google API.
Edit the initialize function in googlemap.js to look like this:
function GoogleMap(){
this.initialize = function(){
var map = showMap();
addMarkersToMap(map);
}
and add the following function, called addMarkersToMap:
var addMarkersToMap = function(map){
var latitudeAndLongitudeOne = new google.maps.LatLng('-33.890542','151.274856');
var markerOne = new google.maps.Marker({
position: latitudeAndLongitudeOne,
map: map
});
var latitudeAndLongitudeTwo = new google.maps.LatLng('57.77828', '14.17200');
var markerOne = new google.maps.Marker({
position: latitudeAndLongitudeTwo,
map: map
});
}
}
5. Zooming out the map to show all markers
To zoom out the map without knowing which zoomlevel to use we are going to use the LatLngBounds object from the Google Map API.
Start off by adding the following line first in the addMarkersToMap function:
var mapBounds = new google.maps.LatLngBounds();
and before the closing tag of the function add these lines:
mapBounds.extend(latitudeAndLongitudeOne);
mapBounds.extend(latitudeAndLongitudeTwo);
map.fitBounds(mapBounds);
The addMarkersToMap function now looks like this:
var addMarkersToMap = function(map){
var mapBounds = new google.maps.LatLngBounds();
var latitudeAndLongitudeOne = new google.maps.LatLng('-33.890542','151.274856');
var markerOne = new google.maps.Marker({
position: latitudeAndLongitudeOne,
map: map
});
var latitudeAndLongitudeTwo = new google.maps.LatLng('57.77828', '14.17200');
var markerOne = new google.maps.Marker({
position: latitudeAndLongitudeTwo,
map: map
});
mapBounds.extend(latitudeAndLongitudeOne);
mapBounds.extend(latitudeAndLongitudeTwo);
map.fitBounds(mapBounds);
}
Now we’re done, run the app and the map now zooms out so you can see the marker which we added in Sweden.

watchPosition do not reset highaccuracy after clearwatch

I'm using watchPosition on a small application and I'm using both high accuracy positioning (GPS) and Coarse Positioning (Network based) to limit battery consumption.
To enable coarse positioning, I use following command :
watchID = navigator.geolocation.watchPosition(onSuccess, onError, { enableHighAccuracy: false });`
and To enable Fine Positioning :
watchID = navigator.geolocation.watchPosition(onSuccess, onError, { enableHighAccuracy: false });
To reset watching, I using clearWatch :
navigator.geolocation.clearWatch(watchID);
Strange thing is that after enabling Fine positioning, I cannot switch back to coarse positioning (GPS icon on android is still on).
for example :
watchID = navigator.geolocation.watchPosition(onSuccess, onError, { enableHighAccuracy: false }); // GPS icon is off which is OK
navigator.geolocation.clearWatch(watchID); //GPS icon still off (OK)
watchID = navigator.geolocation.watchPosition(onSuccess, onError, { enableHighAccuracy: true }); // GPS icon become on (which is OK)
navigator.geolocation.clearWatch(watchID); //GPS icon become off (OK)
watchID = navigator.geolocation.watchPosition(onSuccess, onError, { enableHighAccuracy: false }); // GPS icon is on which is **NOT OK**
I'm using Android 5.1.1.

It is working in Ripple emulator
But it is not working in Android emulator and Genymotion

I figured out the problem.
If i use this code it is working fine
navigator.geolocation.getCurrentPosition(alertmsg, onError, { timeout: 30000, enableHighAccuracy: true });
It is working in all emulators(Ripple,Android,Genymotion)

I'm using Visual Studio 13 with a Backbone based smartphone app and this was a pain. Adding the timeout option and enableHighAccuracy always throws the onError handler, without these neither return.
So this is a good answer:
//Android Emulator safe version
function getGpsCordinates(callback) {
if ("geolocation" in navigator) {
navigator.geolocation.getCurrentPosition(
//Success
function (position) {
console.log("GPS: Success");
callback(position);
},
//Error
function (error) {
console.log("GPS: Error");
var position = {
coords: {
longitude: 0,
latitude: 0,
speed: 0
}
};
callback(position);
},
{ timeout: 7000, enableHighAccuracy: true });
} else {
var position = {
coords: {
longitude: 0,
latitude: 0,
speed: 0
}
};
console.log("GPS: Not Supported");
callback(position);
}
console.log("GPS: Continued");
}
getGpsCordinates(function(mycallback) {
alert(mycallback.coords.latitude);
});

Above code deviceready() function is working fine but alert("It Works!!!"); not working. Please tell me why it is not working in my device emulator?
I am getting error message.
Screenshot:

Increase timeout to '5000' or '10000' and also increase maximumAge

HTML5 geolocation app for Android using phonegap eclipse

I am having trouble to get this HTML5 geolocation app for Android running. The app works fine in Firefox browser from my desktop, but once I compile it using Eclipse - PhoneGap, the geolocation button does not perform the command document.write, I have tried with alert(), as well as console.log(), but there is no positive result.
The code is below, can you please point to me if I am missing setting up any of the phone sensors for geolocation?

document.write seems to be the cause of your problem, rather than a failure in geolocation, assuming of course you have adequate permissions in your AndroidManifest.xml:
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

BTW, there's a typo in your source code </headd> should be </head>.
You should also really use $(document).on("deviceready") instead of $(document).ready() with Phonegap as 'ready' event only indicates DOM is ready whereas 'deviceready' indicates Phonegap has fully loaded.

Androip phonegap GPS accuracy

In the following code i am trying to get the GPS location from the phonegap example.Iam trying this on the actual device and not on the emulator i get a time out every time.I never got the on success alert.What am i doing wrong.i have enable GPS and internet
JS
document.addEventListener("deviceready", onDeviceReady, false);
var watchID = null;
// Cordova is ready
//
function onDeviceReady() {
// Throw an error if no update is received every 30 seconds
var options = { timeout: 30000 };
watchID = navigator.geolocation.watchPosition(onSuccess, onError, options);
}
// onSuccess Geolocation
//
function onSuccess(position) {
var element = document.getElementById('geolocation');
element.innerHTML = 'Latitude: ' + position.coords.latitude + '<br />' +
'Longitude: ' + position.coords.longitude + '<br />' +
'<hr />' + element.innerHTML;
}
// onError Callback receives a PositionError object
//
function onError(error) {
alert('code: ' + error.code + '\n' +
'message: ' + error.message + '\n');
