This is my Below code which only draws one Circle around Current Location as the center. I need to draw a Circle within Circle around the current location on the google map. Total circle should be 5. Radius of each circle should be like this-

Java Code:
Circle 1 radius should be 10m 
Circle 2 radius should be 20m 
Circle 3 radius should be 30m 
Circle 4 radius should be 40m 
Circle 5 radius should be 50m

Below code works fine to create only one circle by taking the current location as the center. But how can I draw other circles with the above specification.

Java Code:
	class MapOverlay extends Overlay {
		private GeoPoint pointToDraw;

		public void setPointToDraw(GeoPoint point) {
			pointToDraw = point;
		}

		public GeoPoint getPointToDraw() {
			return pointToDraw;
		}

		@Override
		public boolean draw(Canvas canvas, MapView mapView, boolean shadow, long when) {
			super.draw(canvas, mapView, shadow);
			//---translate the GeoPoint to screen pixels---
			Point screenPts = new Point();
			mapView.getProjection().toPixels(pointToDraw, screenPts);
			//--------------draw circle----------------------
			Point pt = mapView.getProjection().toPixels(pointToDraw,screenPts);
			Paint circlePaint = new Paint(Paint.ANTI_ALIAS_FLAG);
			circlePaint.setColor(0x30000000);
			circlePaint.setStyle(Style.FILL_AND_STROKE);
			canvas.drawCircle(screenPts.x, screenPts.y, 130, circlePaint);

			//---add the marker---
			Bitmap bmp = BitmapFactory.decodeResource(getResources(), R.drawable.current_user);
			canvas.drawBitmap(bmp, screenPts.x, screenPts.y-bmp.getHeight(), null);
			super.draw(canvas,mapView,shadow);

			return true;
		}


	}
I am having hard time making other circles by taking current location as the center. R.drawable.current_user is the current location
