Hi,

is PDFLayoutView Good to use in production?

I had implement PDFLayoutView in our app, but there is a red color textview overlay on the pdf indicating the AvialMem. how to remove this text view without changing the pdfreader library code.

another question is i need to do some customization in PDFLayoutView. to do that i had wrote a class which extend to PDFLayoutView, but all the PDFLayoutView Variable are private i can't call any variable in my custom class without changing the original library code

i find out that there is several way to display the PDF (eg PDFLayoutView, PDFView and PDFReader). so which one is better to open single page PDF in Fragment viewpager?

Hi,
yes, to remove the AvialMem text follow this guide --> www.radaeepdf.com/support/knowledge-base...component&kbartid=20

To edit the library source code you need a Professional or a Premium license, if you have one of this license you can follow this to get the code.

You can use what you want, I suggest you to look at the PDFPagerAct of RDPDFReader project

PDFLayoutView is is development stage.
The main drawback (the only we're aware about) is that when zooming out and panning a zoomed page you will see blank area until you finish the zoom/pan action.
We're working to enhance that class and to promote in production stage.

About out of memory: it could be related to max zoom and pdf file you're working with.
We are aware some customers are rendering huge file containing A2 pages with high res images and drawings without any issue.
The S3 itself has 1Gb ram that should be sufficient to render high res files.
If you think you're working with particular document structure, please provide us one of them so we could to some check.
