I have a KMZ vector file which works fine on my Google Earth application, but i want to overlay this on my phone (android) through Google maps. Is that possible??? thank you very much Mike
Google Earth for Android devices is available for Free from Google Play Store
This will display your KML/KMZ files.
Currently on version 7.0.1
Just be careful on data usage limits on your Mobile/Cell plan
Not sure if this is quite what you are getting at, but you can view any KMZ (as long as it is under the size limit, not quite sure what that is...) in google maps by referencing its location it in the google maps url:
you can place the url to any kml or kmz after "maps?q=" to view it in google maps (or if you are using the standard google maps search interface, just enter the url to your kml/kmz into the search bar)
This displays the USGS kmz of San Francisco geology in google maps. It works on my iPhone, let me know if this works for your Android.
