Hi Andy,

Welcome to PM!

This is a guess, since I'm not familiar with your smartphone, but I have used PDF::API2 without a problem.

I think you need to update your pdf reader. I checked several pdf files and they were all 1.4 or newer. If that's not possible then I would generate the pdfs as version 1.4 and call a system conversion tool from your script.

I googled the version info, and found the following. It show 1.4 has been available since 2001.

    * (1993) – PDF 1.0 / Acrobat 1.0
    * (1994) – PDF 1.1 / Acrobat 2.0
    * (1996) – PDF 1.2 / Acrobat 3.0
    * (1999) – PDF 1.3 / Acrobat 4.0
    * (2001) – PDF 1.4 / Acrobat 5.0
    * (2003) – PDF 1.5 / Acrobat 6.0
    * (2005) – PDF 1.6 / Acrobat 7.0
    * (2006) – PDF 1.7 / Acrobat 8.0
    * (2008) – PDF 1.7, Adobe Extension Level 3 / Acrobat 9.0
    * (2009) – PDF 1.7, Adobe Extension Level 5 / Acrobat 9.1

Most everyone here would suggest upgrading a 2001 perl. Without knowing more . . .

Good Luck!
