Geolocation positionchanged event -- 0,0 coordinates

The sample code doesn’t really do anything, it’s just this:

namespace Wisej.GeoLocationTest
{
 public partial class Page1 : Page
 {
 public Page1()
 {
 InitializeComponent();
 }

private void button1_Click(object sender, EventArgs e)
 {
 this.geolocation.GetCurrentPosition((l) => {

this.label1.Text = l.ToString();

});
 }


private void checkBox1_CheckedChanged(object sender, EventArgs e)
 {
 this.geolocation.ActiveWatch = this.checkBox1.Checked;
 }

private void geolocation_PositionChanged(object sender, EventArgs e)
 {
 this.label2.Text = this.geolocation.LastPosition.ToString();
 }
 }
}

I don’t know what caused the error you see. It’s strange that it mentions a link to googleapis. It’s possible that the browser is using google apis to geolocate. Weird. See this: https://stackoverflow.com/questions/41137594/network-location-provider-at-https-www-googleapis-com-returned-error-code

There are many posts with the same error.

Now I can’t get Chrome to work at all. Right now I’m getting this from your test site on Chrome — Firefox works.

In my project, I can see “PositionUnavailable”, but not the same details that https://wisejgeolocationtest.azurewebsites.net provides. Is the source available ?

Yes, it seems to work now provided it is always Https.  It seems that’s a feature introduced in Chrome 50 — need SSL for Geolocation. I’ll probably just use Firefox while debugging geolocation routines on mobile.  Thank you for the help.

You can retrieve the Status property of the Position parameter passed to GetCurrentPosition() or using the LastPosition property.

It returns one of the Wisej.Ext.Geolocation.StatusCode values.

It works with https?

Yes, works on desktop, on mobile it didn’t fire because I didn’t append https:”PermissionDeniedError” “Only secure origins are allowed (see: https://goo.gl/Y0ZkNV).

This would explain some of the behavior I’m getting. After clearing Chrome settings on desktop and mobile.

— I can get localhost to display the location request pop-up

— I can get the production site to display the location request pop-up (with HTTPS)

— the alias site that goes to the dev machine does not display a pop-up request. (no HTTPS)

In your demo, that status information (PermissionDenied) would be useful — is that available as a member of the Geolocation object?

thanks,

Did you try this? https://wisejgeolocationtest.azurewebsites.net/

I’ll see if I can get hold of Chrome Mobile 59.0.3071.125

Thanks for that. It’s not the browser, because I can get other sites to generate the pop-up “xxxxxx wants to know your location (Allow/Block)”.  I can’t get WiseJ to generate that on Chrome Mobile 59.0.3071.125 (Android 5.0.1).  It doesn’t matter if I have the Timeout property set to -1 or 10000.  I also checked Chrome’s Location settings to make sure the URL was not blocked.

The PositionChanged event does fire, however… but it’s always null coordinates.

Don’t know. We use the browser’s geolocation. Look at this thread, there are a couple of links to test apps. There was a problem with older iPhone devices that we fixed:
