drawCircle requires diameter in pixels. In order to convert accuracy (in meters from LocationProvider) into pixels you can do this: - convert current location (GeoPoint) into pixels using mapView.getProjection.toPixels() - create another GeoPoint with longitude = center.getlatitudeE6() + accuracy * 11 - also convert this position into pixels - get delta between Y coordinates those two points. This is the radius of your circle.
