Please upload a sample project which shoes the issue. Include your pdf in the project...
Based on the error you are accessing an not existing pageindex....

As i wrote. the problem is that you are accessing a page which does not exists.
Please note that the example is wrong. It expect the pages are from 1 to somewhat... But the pages have index 0 to x-1

This works for me on my Note 8 (Android 7.1)

        lblPages.Text = pdf.PageCount-1
        lblPages.Tag = pdf.PageCount-1
        lblPage.Text = 1
        lblPage.Tag = 1
        'pdf.InitialRender(bmp)
        image.Bitmap = pdf.renderPageforDisplay(0)

Check this example: https://www.dropbox.com/s/oicpn1dfdrh7zjd/PdfRenderer2Ex.zip?dl=0

PD: i´m pretty sure that it does not work on every other android version using the wrong indexes.... Even 5.1

Thanks working fine now...

Actually Problem in Page index

I have to put "0" instead "1"
