App keeps crashing when adding mapview

Recently, i have tried to implement mapview into my app. However, the app keep crashing whenever the google map is displaying and it keep gives me error

msg:java.lang.IllegalStateException: Map size should not be 0. Most likely, layout has not yet occured for the map view

first i created the mapview

var samplemap  = MapModule.createView({
            mapType:MapModule.NORMAL_TYPE,
            userLocation:true,
            width:Ti.UI.FILL,
            height:Ti.UI.FILL,
            visible:false,
        });
 
samplemap = createGoogleMapView();
samplemap.setEnabled(false);
samplemap.setTouchEnabled(false);
samplemap.setEnableZoomControls(false);
samplemap.setUserLocationButton(false);

then i set the annotations into mapview

samplemap.addAnnotations(annotations);
samplemap.setRegion(region);
samplemap.show();

I have tested this app in htc incredible s and htc one. HTC incredible will crash frequently while htc one will crash for the first time only.

Any ideas?
