Android : "Uncaught Referenceerror: google is not defined"on Android 4.4.2 when trying to inject javascript to a html file that loads googlemap

on Wednesday, July 9, 2014


I would like to load a google map using a WebView and show some markers on it. Due to some limitations I can only use WebView for loading the map and not MapFragment. So I create a webview and loadurl for a html file stored in the assets folder. (Btw these html files all load perfectly on a PC browser but do not render on the tablet.). I am NOT able to find out the root of the error and why the html/javascript renders on the PC but throws error on the mobile. Please help!! -Thanks



mapinit.html
<html>
<head>
    <meta http-equiv="Content-type" content="text/html; charset=utf-8"/>
    <title>Example</title>
    <script src="http://maps.google.com/maps/api/js?v=3.exp&sensor=true"></script>

    <script type="text/javascript" charset="utf-8">

        function initializeMap() {
            var mapOptions = {
                zoom : 12,
                center : new google.maps.LatLng(37.401324, -122.053624),
                mapTypeId : google.maps.MapTypeId.ROADMAP
            };

            map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);

        }

        function myOnLoad() {
            initializeMap();

        }

    </script>
</head>

<body onload=myOnLoad()>
    <div id="demo"></div>
    <div id="map-canvas" style="height: 1500px; width: 1500px;"></div>
</body>



Android code:
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.webview_activity_main);
    mWebView = (WebView) findViewById(R.id.webview);

    mWebView.loadUrl("file:///android_asset/mapinit.html");
    mWebView.getSettings().setJavaScriptEnabled(true);


}


Error:
