To draw a circle around a marker in Google Map on Android, use the Google Maps API. First, ensure you've implemented the Google Maps API in your Android project. Then, create a `CircleOptions` object and set its properties such as radius (in meters), center (the marker's position), stroke color, and fill color. Finally, add it to your Google Map instance with `map.addCircle(circleOptions)`. This method allows you to visually represent areas around a point, like showing coverage or distance from a specific location.
