I have tested this method(AddAnnotBitmap).
It works well.

But when I tested it on my app, it doesn't work....

My app is professional license.
I don't know the reason.

Log.e("success", "count: " + page.GetAnnotCount() + " / success : " + success);
count is 0, success is true.

Page page = mDoc.GetPage(1);
page.ObjsStart();
float rect[] = new float[4];
rect = new float[] { 200, 200, 241, 241 };
boolean success= page.AddAnnotBitmap(bmAddnot, true, rect);
Log.e("success", "count: " + page.GetAnnotCount() + " / success : " + success);
mPDFView.vRenderSync(mPDFView.vGetPage(1));
invalidate();
page.Close();

Hi,
you need to rerender the page after your code.
You have to recall the object page after the rendering to get the correct page.GetAnnotCount().

Check this:

What are the "recall the object page" and "rerender the page" ?
Can you give me some sample codes?

Other api methods are done. (AddAnnotMarkup(), AddAnnotStamp() ... )
I don't understand your link...

Hi,

- invoke PDFView.vRenderAsync(PDFVPage page) to rerender page after page modified

- Page page = mDoc.GetPage(1);
page.ObjsStart();
Log.e("success", "count: " + page.GetAnnotCount() + " / success : " + success);

to recall the object page after the rendering to get the correct page.GetAnnotCount()

In the links you can see some example of AddAnnotationBitmap and you can read some advice to do it properly.
