Unable to create serializer "com.esotericsoftware.kryo.serializers.FieldSerializer"

I get the bellow error when trying to create a WaspDb. Any idea what went wrong ?

It looks like an exception inside the kryo library, used by WaspDB. Could you provide a sample code? And, if possible, the Android version/device used?

I'm testing on a Nexus 5 with Android 6.0.1. The app is pretty big, I'll try to isolate a sample code. This is called in Application.onCreate() so at the very beginning.

[martinbonnin]

Looks like a proguard issue....

Got it working with:

-keep class net.rehacktive.waspdb.** { *; }
-keep class com.esotericsoftware.kryo.** { *; }

thanks. I'll add the suggestion on the documentation.
