and MyPositionOverlay is also here.....

public class MyPositionOverlay extends Overlay {
    private final int mRadius = 5;
    Location location;

    public Location getLocation() {
        return location;
    }

    public void setLocation(Location location) {
        this.location = location;
    }

    @Override
    public void draw(Canvas canvas, MapView mapView, boolean shadow) {
        Projection projection = mapView.getProjection();
        if (shadow == false) {
            // Get the current location
            Double latitude = location.getLatitude()*1E6;
            Double longitude = location.getLongitude()*1E6;
            GeoPoint geoPoint;
            geoPoint = new GeoPoint(latitude.intValue(),longitude.intValue());

            // Convert the location to screen pixels
            Point point = new Point();
            projection.toPixels(geoPoint, point);
            RectF oval = new RectF(point.x - mRadius, point.y - mRadius,
                point.x + mRadius, point.y + mRadius);

            // Setup the paint
            Paint paint = new Paint();
            paint.setARGB(250, 255, 0, 0);
            paint.setAntiAlias(true);
            paint.setFakeBoldText(true);
            Paint backPaint = new Paint();
            backPaint.setARGB(175, 50, 50, 50);
            backPaint.setAntiAlias(true);
            RectF backRect = new RectF(point.x + 2 + mRadius, point.y - 3*mRadius,
                point.x + 65, point.y + mRadius);

            // Draw the marker
            canvas.drawOval(oval, paint);
            //canvas.drawLines(pts, paint);
            canvas.drawRoundRect(backRect, 5, 5, backPaint);
            canvas.drawText("I am here", point.x + 2*mRadius, point.y, paint);
        }
        super.draw(canvas, mapView, shadow);
    }
}

Use the LocationManager to register for location updates. You indicate which level of granularity you want by specifying a provider. For cell tower updates, use the NETWORK_PROVIDER.
