NPE in annotation.setIcon(String, PageContent) was created by Gomiero

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

Code:

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.

you can use Page.AddAnnotBitmap instead.
Page.AddAnnotBitmap and mDoc.NewImage(b, true) need you call Document.setCache() after Document.Open();

at last: Bitmap to be add, must be RGBA32 format, otherwise failed.

Thank you for the response

After Page.AddAnnotBitmap I must call view.vRenderXXX, correctly? What should I choose between view.vRenderSync and view.vRenderAsync? And why?

Thanks
