There was a problem hiding this comment.
Hey @YOEL311, thanks for investigating and putting up a PR!
I'll keep the guard statement which might protect against the NPE. 👍
This might stop crashes, but I have a feeling it will not fix the root issue and some of your users may not be able to load pdfs.
I took a look at the original repo and think that the issue is probably due to this
I'll implement the fix of moving thread creation from the constructor into onAttachedToWindow.
I am also a bit hesitant to integrate any of the gradle changes so I will likely leave those out for now.

- the thread creation and recycling was not being handled symmetrically - this fix is based off of these two PR: DImuthuUpe#824 and #2
