View annotation as InfoWindow
There are several ways to add markers, annotations, and other shapes to the map using the Maps SDK. To choose the appropriate approach for your application, read the Markers and annotations guide.
Android Examples App Available
This example code is part of the Maps SDK for Android Examples App, a working Android project available on GitHub. Android developers are encouraged to run the examples app locally to interact with this example in an emulator and explore other features of the Maps SDK.
