Android release only RemoteServiceException

Hi guys.

We're experiencing extremely weird crashes lately in our application. They appear to be absolutely random (sometimes once 12-24 hours, sometimes once an hour) and they're only happening on the release version of the application. We're using our custom Java plugin to connect with EEG (with Bluetooth). The only piece of information that was found is that stack trace below.

Does anyone have any idea how to deal with this?
