[Bug]: OutOfMemoryError: App crashes when attempting to load large note #761

Open maarriaa opened 3 days ago

maarriaa commented 3 days ago

What happened?

I have multiple notes in my Butterfly app. When I open the app, it takes quite a long time to load the list of all the notes and then open the selected note.

This time I was trying to open a bigger note - with multiple pages and many strokes on each of the pages but the app kept crashing (logs attached).

I have also often experienced the issue, where the app is lagging while creating a note with too many strokes as the one described here: https://github.com/LinwoodDev/Butterfly/issues/547

Version

2.2.1

Platform

Android

Hmm, out of memory errors are always tricky. And it happens after opening the file? How big is your file?

maarriaa commented 3 days ago

I clicked on the file and it started to load. The app crashed after a few seconds of loading. The file is 70MB
