make sure to rerender the page after adding the annotation..i've tested your code and it's working..

Code:

Bitmap bmAddnot = BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher);
float[]rect = new float[]{0, 0, bmAddnot.getWidth(), bmAddnot.getHeight()};
PDFView m_view = m_vPDF.PDFgetView();
PDFVPage v_page = m_view.vGetPage(m_page_no);
Matrix mat = v_page.CreateInvertMatrix(m_view.vGetX(), m_view.vGetY());
mat.TransformRect(rect);
vpage.GetPage().AddAnnotBitmap(bmAddnot, true, rect);
m_vPDF.invalidate();

After I added m_vPDF.invalidate(); it still show nothing on screen just only PDF

I also tried with PDFReaderOldAct

Page page = m_doc.GetPage(0);
page.ObjsStart();
float[] rect = new float[4];
rect[0] = 0;
rect[1] = 0;
rect[2] = 100;
rect[3] = 100; page.AddAnnotBitmap(BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher), false, rect);
m_doc.Save();
m_vPDF.invalidate();

there is no icon showing. What did I miss ?

Are you trying with the demo project, or yours? if yours do you have the professional or premium license??

Does the method page.AddAnnotBitmap returns true?

Both but I haven't use the license yet because I haven't finish my feature so I make a duplicate project and try with the same package name of demo project com.radaee.reader. If my understanding was right it should enable all of the feature like premium license right ?

addAnnotBitmap always return true with my duplicate project.

Code:

Bitmap bmAddnot = BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher);
float[]rect = new float[]{0, 0, bmAddnot.getWidth(), bmAddnot.getHeight()};
PDFView m_view = m_vPDF.PDFgetView();
PDFVPage v_page = m_view.vGetPage(m_page_no);
Matrix mat = v_page.CreateInvertMatrix(m_view.vGetX(), m_view.vGetY());
mat.TransformRect(rect);
vpage.GetPage().AddAnnotBitmap(bmAddnot, true, rect);
m_view.vRender(vpage);
m_vPDF.invalidate();

like this?
to be notice: Bitmap object must be ARGB_8888 format.

Yes. Even when I created Bitmap object
I created like this Bitmap.createBitmap(bmWidth, bmHeight, Bitmap.Config.ARGB_8888);

Previous snippet code it's just for testing with default icon of project but it doesn't show anything.

Time to create page: 0.391 seconds
