Hi,

I really new on Android development, and this might be a stupid question. How to use VSetPos? I read in the document and tried to start the document to the specific page and specific position on that page. However, I tried using VSetPos but nothing happened.

Second, about GoToPage, where is the best place should I put it into my code to make the document starts and go to the specific page I want? (now I put it on OnDraw() and add flag to make it be called only one time).

Lastly, how to get the current page, or should I calculate by current position divided by page height?

Thank you in advance for answers. ;)

To go to certain position try:
m_reader.vSetScale(m_reader.vGetScale(), x, y);

To open the pdf on a certain page:
m_reader.PDFOpen(m_doc, false, this);
m_reader.PDFGotoPage(10);

to get the current page:
You can get it from OnPageChanged when you implement PDFReaderListener, or you can add a get method in PDFReader for the value of the variable m_pageno
