Sure I’ll try and get a log now (the device has wiped the log since the last time it happened). My first thought was that the SDK has an issue, rather than your plugin. Sometimes it might happen on the first ad request I make in a session, other times I can request 20 ads without a problem.
On a similar note, the android Chartboost ads have always been much slower for us. The time between the ad being “dismissed” and the game actually resuming is around 3 seconds at best on Android, it seems to be much faster on iOS. So it’s probably fair to say that the Android SDK is not as stable.
I’ll post again once I get the error.
Edit: Just called show() 50 times in a row with no error. My colleague has just sent me a message saying he had the same error about 5 mins ago but wiped his log. I think I’ll just have to wait until it happens and then grab the log as quickly as I can.
