Hi Nadja, you are right, HTML is situable for all devices. But I want use some hardware specifics like menue button or camera. For this I found no (simple) HTML solutions. Thats's the reason for the Android App.
> ... Probably this solution require more work. ... Not really. Less then 800 lines of source code (including a lot of comments) in Basic4Android (B4A). If you are interested, take a look on their http://www.basic4ppc.com homepage and the http://www.basic4ppc.com/forum/index.php community . Sorry, it's "only" Basic, but I like this language. > ... Which API did you use for this function? Did you make the same with > HTML solution? ... In B4A I can use a spcific GPS library. In our browser based Application we use the HTML 5 geolocation API, as Jackie answered. Here the Code: ################################### //anfang GPS-Position holen function getLocation() // called by the menue frame { navigator.geolocation.getCurrentPosition(showLocation, showError, {timeout:40000, enableHighAccuracy:true}); } function showError(error) { alert(error.code + ' Fehler' + error.message); } function showLocation(position) { var hoehe = position.coords.altitude; var lat = position.coords.latitude; var lon = position.coords.longitude; var praez = position.coords.accuracy; if(navigator.appName.search("Microsoft") > -1) { resObjekt = new ActiveXObject("MSXML2.XMLHTTP"); } else { resObjekt = new XMLHttpRequest(); sndReq(lat, lon); }//if (navigator...) } function sndReq(lat,lon) { // Koordinaten holen var link = '../autogis/EAAG_MOBIL_TRANS.PHP?x=' + lon + '&y=' + lat; resObjekt.open('get', link, true); resObjekt.onreadystatechange = handleResponse; resObjekt.send(null); } function handleResponse() { if(resObjekt.readyState == 4) { var skalierung = top.ViewerFrame.mapFrame.GetScale(); var ergebnis = resObjekt.responseText; var splitter = ergebnis.split("#"); var zx = splitter[0] * 1.0; var zy = splitter[1] * 1.0; alert (zx); alert (zy); top.ViewerFrame.mapFrame.ZoomToView(zx,zy,skalierung,false); } } ################################### Calling of EAAG_MOBIL_TRANS.PHP is necessary for coordinate transforming, because we are working in a specific german coordinate system. Hope this help you a little bit. Best Regards - Peter ----- IBB INGENIEURBÜRO BATTEFELD AutoGIS mit MapGuide Open Source Bad English?
