Are you saying that this happens only on KitKat devices?

[silviahisham]

Yes always, I reproduced it on 2 Kitkat devices.

My impression is that some info is missing here. Is there a "caused by" section of the exception, for example?

[silviahisham]

Sorry, the crash turned out to be because of an issue related to MultiDex not ObjectBox

Thanks for the update, closing then. For anybody with this issue, please carefully read the Multidex documentation. -ut
