Are you using the Android n.n Platform library? I think you need the Android n.n Google APIs library.

It can be downloaded via the Android SDK and AVD Manager.

If the app is run on a device that does not come with the Google Maps app, then there is nothing you can do. It is owned by Google, and if the device does not come with it you cannot provide it yourself.
