Map module error, app doesn't show map

Hello everyone, (OSX 10.9.3), I have a problem with the new ti.map add-on module. This is my code and my error when my app runs on my device (Galaxy Nexus) and it should show the map... the map doesn't appear, it appear only a white view with plus and minus symbols, the word "Google" and the GPS symbol. I tried with map module 2.1.4 and 2.1.5, I controlled the API KEY, and I also regenerated it, I set the tiapp.xml file like it should, I already tried all the solution I could find in this foum. I don't know what else can I do =( I didn't install Android samples but I think it shouldn't be a problem.

function crea_mappa(lat, lon, rivenditori, propName){   
 
var Map = require('ti.map');
 
var annotazioni = [];
 
for (var i=0; i<rivenditori.length-4; i++){         
    annotazioni[i] = Map.createAnnotation({
        latitude:  parseFloat(rivenditori[i][propName[8]]),
        longitude: parseFloat(rivenditori[i][propName[9]]),
        title: rivenditori[i][propName[0]],
        subtitle: rivenditori[i][propName[1]],
        pincolor: Map.ANNOTATION_RED,
        animate: true,
        myid: i //Custom property to uniquely identify this annotation
    });
}
 
mapView = Map.createView({
    mapType: Map.NORMAL_TYPE,
    region: {latitude: lat, longitude: lon,
            latitudeDelta: 1, longitudeDelta: 1},
    animate: true,
    regionFit: true,
    userLocation: true, //mostra la posizione dell'utente con un pin
    annotations: annotazioni,
    height: Ti.UI.FILL,
    backgroundColor: 'black',
    top: 6
});
 
//for the iOS platform, wait for the complete event (fired when the map completes loading) to ensure the region is set 
if (Ti.Platform.name == 'iPhone OS') {
    mapView.addEventListener('complete', function(evt){
        mapView.region = {
            latitude: lat, longitude: lon,
            latitudeDelta: 1, longitudeDelta: 1
        };
    });
}
 
mapVadded = false;
}

This error appears either I put the zip module in Resources folder, or unzipped module in Application Support/Titanium/modules/android/ti.map
