Maps on Symbian phone
ruiran
I have implemented a simple application with Google Maps API v3 on
Nokia N95. The function is very similar with “Google map” on Symbian
phones, and now I just only first load a HTML file like this:
******************************************************************************************
<html>
<head>
<meta name="viewport" content="initial-scale=1.0, user-scalable=no" />
<meta http-equiv="content-type" content="text/html; charset=UTF-8"/>
<script type="text/javascript" src="http://maps.google.com/maps/api/js?
sensor=true"></script>
<script type="text/javascript">
var myOptions = {
zoom:8,
mapTypeId: google.maps.MapTypeId.ROADMAP,
}
var map;
function initialize() {
var myLatlng = new google.maps.LatLng(39.9208, 116.4001);
map = new google.maps.Map(document.getElementById("map_canvas"),
myOptions);
map.setCenter(myLatlng);
}
</script>
</head>
<body style="margin:0px; padding:0px;" onload="initialize()">
<div id="map_canvas" style="width:100%; height:100%"></div>
</body>
</html>
*************************************************************************************
Then if the location changed, I can get the latest info of the current
latitude and longitude and then using the following codes to update
the Maps：(using "Qt for Symbian" for development )
QStringList scriptStr;
scriptStr
<< QString("var myLatlng = new google.maps.LatLng(%1,
%2);").arg(longitude).arg(latitude)
<<"map.setCenter(myLatlng);";
map->page()->mainFrame()->evaluateJavaScript(scriptStr.join("\n"));
On SDK emulator it is able to run well and get the maps according to
current position but memory leak comes out and it would be down
automatically, and running it on N95 I even can‘t get the current
maps(longitude and latitude is absolutely get by other codes), so
could you help me?

to get some functionality to work, but it is highly unlikely that
everything documented would work as listed.
In other words, you are kind of on your own.
