learning the google maps v2 API for android
uses CityBikes open source bikeshare API https://citybik.es/#about
If you intend on using this you will need to create a file at /res/values/google_maps_api.xml like so:
<resources>
<!--
TODO: Before you run your application, you need a Google Maps API key.
To get one, follow this link, follow the directions here:
https://developers.google.com/maps/documentation/android/start#get-key
Once you have your key (it starts with "AIza"), replace the "google_maps_key"
string in this file.
-->
<string name="google_maps_key" templateMergeStrategy="preserve" translatable="false">YOUR_KEY_HERE</string>
</resources>
