Hi all,
I have a NullPointerException in method PageContent.DrawImage(ResImage) when I use Annotation.setIcon(String, PageContent). My code is:

Bitmap b = BitmapFactory.decodeResource(getResources(), R.drawable.ic_media_image);
PageContent p = new PageContent();
p.Create();
DocImage di = mDoc.NewImage(b, true);
					
annotation.SetIcon("short text", p);
p.DrawImage(page.AddResImage(di));

Particularly the method Page.AddResImage(DocImage) returns null because the native method addResImage(int, int) returns 0.
Library version is 3.0

What do I wrong?

Thanks.
