IllegalStateException (R.id.versionTextView) must not be null

[sebastinto]

Hi there!

I have been having a recurring issue with the lib recently. Please view logcat below.

How could I begin to investigate this issue? Thanks!

Well, the issue went away on its own. Weird.

This is concerning as it appeared seemingly out of nowhere - no modifying code related to this lib - and also went away without intervention.

I'd still be interested to get some advice on what would be the best approach to figure out what could have been causing the issue in case it resurfaces.

Thanks!
