Get your own Google Maps API Key
NOTE: Usage of this code with the free Google Maps API Key breaks Google's Terms and Conditions (section 10.8). You should purchase an Enterprise License if you wish to use the Google Maps API as shown in this example.
To use the following code, you should get your own Google Maps API Key. If you have not an API key, you can follow the instructions here: How to use Google Maps data in mobile applications
Use a Proxy server to access Google Map services
Note: this subject (proxy usage) is probably non necessary, still investigating it..
When you sign up to obtain a Google Maps API key, you enter the address that will be able to access Maps services with that key. For this reason, you should setup a Proxy server on that address that will receive HTTP requests from your mobile clients, forwarding them to Google Maps services, giving back Google responses.
In the code below, you should forward the following requests:
http://www.yourserver.com/geo requests to http://maps.google.com/maps/geo
http://www.yourserver.com/staticmap requests to http://maps.google.com/staticmap
