another app for analysis for creating pdfs in android. i use this one specifically: https://play.google.com/store/apps/details?id=in.gnuasia.pdfwriter
thanks for suggestions but this is not the right place to post it. this is LibO bug tracker and is intended to report bugs about LibreOffice itself. you should post this in forums or users mailing list. thank you.
