Google offers a variety of services that help you enhance your app's capabilities, build new revenue streams, manage app distribution, and track app usage.
Because these services are offered directly by Google, they're not included in the Android platform. Some are provided by the Google Play service available on devices with Google Play, and others require a library added to your app.
The power of Google Maps is available to your app with an embeddable map view. You can customize the map with markers and overlays, control the user's perspective, animate the camera, and much more.
