The Woosmap Geofencing Android SDK is based on a core SDK that allows tracking of user location and stops, as well as interacting with various Woosmap APIs like the Woosmap Store Search API or the Woosmap Distance API. The source code for this core SDK is publicly hosted on this GitHub repository and is fully open source, so you are free to fork it as needed.
However, to take advantage of all the advanced features that Woosmap offers, such as Woosmap Assets proximity monitoring, isochrone geofences, preset tracking profiles, and connectors, you will need to use the Woosmap Geofencing Android SDK that is distributed through Sonatype Nexus repository.
All feature descriptions and guides to implement the Woosmap Geofencing Android SDK are available on the Woosmap developers documentation.
