PhoneGap + Google Maps API v3 : Not displaying (at all) on Android

Question

The Situation

I\'m currently developing an app for a customer, who wishes to have a Google Maps integration. He wants the map to show the route from

Answer 1

I never solved this directly, but I started using Intel's App Framework, which had an example plugin for google maps (the original link is dead, see edit below). This plugin works great for me and I was able to add directions to it.

The code I ended up using is below. No permissions or any other adjustments needed. See the comments in the code. The map will show up regardless of geolocation success or error, but if it gets the current position it adds directions to the map. Otherwise it shows a static point.

(function () {
    var gmapsLoaded = false; //internal variable to see if the google maps API is available

    //We run this on document ready.  It will trigger a gmaps:available event if it's ready
    // or it will include the google maps script for you
    $(document).ready(function () {
        if(window["google"]&&google.maps){
            $(document).trigger("gmaps:available");
            gmapsLoaded = true;
            return true;
        }
        var gmaps = document.createElement("script");
        gmaps.src = "http://maps.googleapis.com/maps/api/js?v=3.exp&sensor=true&callback=gmapsPluginLoaded";
        // Updated API url
        $("head").append(gmaps);
        window["gmapsPluginLoaded"] = function () {
            $(document).trigger("gmaps:available");
            gmapsLoaded = true;
        }
    });

    //Local cache of the google maps objects
    var mapsCache = {};

    //We can invoke this in two ways
    //If we pass in positions, we create the google maps object
    //If we do not pass in options, it returns the object
    // so we can act upon it.

    $.fn.gmaps = function (opts) {
        if (this.length == 0) return;
        if (!opts) return mapsCache[this[0].id];
        //Special resize event
        if(opts=="resize"&&mapsCache[this[0].id])
        {
            var map = mapsCache[this[0].id];
            var center = map.getCenter();
            google.maps.event.trigger(map, "resize");
            map.setCenter(center);
            map.setZoom(13);
            // Extended resize to recenter and reset zoom

            return map;
        }

        //loop through the items and create the new gmaps object
        for (var i = 0; i < this.length; i++) {
            new gmaps(this[i], opts);
        }
    };
