Inserting map overlays on circle path according to some point in the middle

Issue

Let's say I have a point like lat:41.01522 and lon:28.95221. I need to calculate X latx and lonx so that these points create a circle (evenly distrubuted) around this point with a given radius.

any idea how?

Solution

This is how I'm doing it:

@Override
public void draw(Canvas canvas, MapView mapview, boolean shadow) {
    super.draw(canvas, mapview, shadow);

        if(location != null){
            //---translate the GeoPoint with center to screen pixels---
            screenPts = new Point();
            mapview.getProjection().toPixels(new GeoPoint((int)(location.getLatitude()*1E6),(int)(location.getLongitude()*1E6)) , screenPts);


            //Draw accuracy marker
            GeoPoint g0 = mapview.getProjection().fromPixels(0, screenPts.y);
            GeoPoint g1 = mapview.getProjection().fromPixels(width, screenPts.y);
            l0.setLatitude(g0.getLatitudeE6()/1E6);
            l0.setLongitude(g0.getLongitudeE6()/1E6);
            l1.setLatitude(g1.getLatitudeE6()/1E6);
            l1.setLongitude(g1.getLongitudeE6()/1E6);
            float d01=l0.distanceTo(l1);
            int size=(int)(location.getAccuracy() * width / d01);
            canvas.drawCircle(screenPts.x, screenPts.y, size, paintAccuracyFill);
            canvas.drawCircle(screenPts.x, screenPts.y, size, paintAccuracyStroke);
        }
}

Good luck, Luis
