Incorrect localization of markers on map. Strange behaviour of markers on the map [android help]

Incorrect localization of markers on map. Strange behaviour of markers on the map

I works with OSMdroid. I extended the Overlay class and I overridden the draw method to my needs. And I have a problem with placing of markers. When I display them for the first time they have wrong location. But when I start zooming they move and after couple of zooms they have correct localization.

Here is my code:

protected final Rect mRect = new Rect();
protected Point mScreenPts = new Point();

@Override
protected void draw(Canvas c, MapView osmv, boolean shadow) {
    Projection pj = osmv.getProjection();

synchronized (mInternalItemList) {
        if (shadow && !mInternalItemList.isEmpty()) {
            for(int i = 0; i < mInternalItemList.size(); i++) {
                CustomizedItem customized = mInternalItemList.get(i);

pj.toMapPixels(new GeoPoint(customized.getLatitude(),
                                customized.getLongitude()), mScreenPts);


boundToHotspot(customized.getDrawable(), HotspotPlace.LOWER_LEFT_CORNER);

Drawable draw = customized.getDrawable();

draw.copyBounds(mRect);
draw.setBounds(mRect.left + mScreenPts.x, mRect.top + mScreenPts.y, 
               mRect.right + mScreenPts.x, mRect.bottom + mScreenPts.y);

draw.draw(c);
draw.setBounds(mRect);
                           }
                       }
                   }
}

Thank in advance.
