I do not see annotations in pdf in application after using pdfRenderer.Page.render()
It was also not possible, because Android does not support it in pdfRenderer, which is used by 'pdfx'.
But it looks, that pdfRenderer has been expanded for Androind in API level 35. There is a new funciton 'render' for pdfRenderer.Page, in which new params (RenderParams) can be set: FLAG_RENDER_TEXT_ANNOTATIONS, FLAG_RENDER_HIGHLIGHT_ANNOTATIONS.
Describe the solution you'd like
It would be great to update 'pdfx' and add supprtion of annotations in pdf.
Describe alternatives you've considered
no alternatives
