I am experimenting with making Blackberry widgets but having a little trouble.
My first trial involves displaying a button which, when clicked, calls a JavaScript function that should alert the phones latitude and longitude.
The function looks:
function whereAmI() {
var latitude = blackberry.location.latitude;
var longitude = blackberry.location.longitude;
alert("Lat: "+latitude+", Long: "+longitude);
}
But it only ever alerts "Lat: 0, Long: 0". I've checked and my GPS seems to be working ok.
I'm running OS 5.* on a Curve 8900.
Any help would be appreciated :)
I discovered that I wasn't signing my files properly - now that I have, everything works fine.
For kaban:
// called when location object changes
function locationCB()
{
alert("Latitude " + blackberry.location.latitude);
alert("Longitude " + blackberry.location.longitude);
return true;
}
// test to see if the blackberry location API is supported
if( window.blackberry && blackberry.location.GPSSupported)
{
document.write("GPS Supported");
// Set our call back function
blackberry.location.onLocationUpdate("locationCB()");
// set to Autonomous mode
blackberry.location.setAidMode(2);
//refresh the location
blackberry.location.refreshLocation();
}
else
{
document.write("This Device doesn't support the Blackberry Location API");
}
Does your widget have permission to use GPS? Go to Options->Applications, select your app, then "Edit Permissions". Make sure "Location Data" (in Connections) is set to Allow.
