Is it possible to make the GeoFence option on Android\iOS?

Question

Android

Colleagues question. Is it possible to embed the functionality of "drawing a geo-zone" on the Google Maps map (possibly through the API) into the Android\iOS device applications.
The meaning is this:
1. We launch the application on Android \ iOS
2. A map is loaded there (through the GoogleMaps built into the browser) (with a specific location) where the phone is located.
2.1 A circle or a triangle, for example, indicating the initial geofence
3. He moves these lines and points with his fingers (the figure may change)
4. Presses the send button, data with the GeoFence coordinates are transmitted via API, in the form of a single line (39.82849, -121.63748) ( 39.85643,-121.81413) (39.77679,-121.91938) (39.62849,-121.83748) (39.72223,-121.68529)
