NoClassDefFoundError when accessing inner class from external library

I have an application which uses library, which in its turn has external JAR in it - Cardboard SDK.

App compiles but in runtime I get NoClassDefFoundError - it cannot find inner class CardboardDevice$DeviceParams from cardboard SDK.

Full stack trace:

The Cardboard SDK includes a libprotobuf jar file. Make sure it is present and being included in your build.
