Bug description

I am receiving some OOM issues from my released app on Android only (this happens much less than before with the latest release) when people are loading large PDFs (80MB+).

The app is crashing because of OOM, while i was hoping for a preloading of 1 page before / after, but not the whole document when a pdf is read.

Steps to reproduce

Try to read a very large PDF (80MB+ is crashing in my app because my app already uses 200MB more or less so the threshold is lowered than in an example app).

Hi,
The OOM (Out of Memory) exception is not related to the overall size of the PDF document but rather to the content and dimension of individual pages. Could you please try enabling the largeHeap option in your AndroidManifest.xml file and check if this resolves the issue?

If the above solution does not work on your end, could you please share the PDF file in which the issue occurs, as this problem appears to be specific to the document? This will help us identify the root cause and provide you with a prompt solution.

If you feel that the documents cannot be shared publicly, you may create a ticket in our support portal to share the requested files securely.

Thanks for your answer, i will try to start with the largeHeap parameter to see if it's enough and get back to you after my next app release this week !
