In my Developer Console, occasionally I see a spike in the following crash:
java.lang.IllegalArgumentException

Is this beyond my control? None of the above crash report actually relates directly to any method or class in my project, so I have no idea where to look. Furthermore, I am seeing none of these errors at all for weeks on end, then suddenly a spike over a couple of hours, then back to nothing:
The spikes don't coincide with any even I recognise, e.g. a new version release. This suggests to me that there's nothing much I can do, though it's annoying because it does seem to feed in to the Android Vitals stats. Also, the crashes are coming in from a whole range of Android versions and devices.
EDIT and since I first submitted this, a few days ago, there have been no further crash reports in this category:
EDIT2... and now I'm seeing more instances of this error... I haven't published any update to my app in this time frame so it's nothing I've broken (and it is really affecting my Android Vitals stats):
EDIT3... aaargh! Look at it now (haven't published a new version of the app for a couple of months now... so it's nothing I've done):
