Our Firebase crashlytics service reported a crash from the Launch Darkly SDK, which I am posting here:

Hi @Daniel-Glucksman,

Thanks for reporting. This error is currently prone to happen when the Android SDK attempts to send this event on a device without a network connection. This was previously reported as #107. To keep our issue tracker clear of duplicates I'm going to close this and ask that you follow that ticket for updates.

We've already fixed the issue on our private mirror and will include it in the next Android release. Watch #107 for updates.

Cheers,
@bwoskow-ld
