Hi, I had this problem in my app too, the problem was that I changed my Java's packages structure and I was using Hawk to store an instance of one of my objects. Hawk stores the path of the class to recreate it with GSON, when I was trying to get my object back there was an error because it had the old path to my class and couldn't know that I moved my class in an other package.

👍 I'll check and maybe change the implementation a little bit.

I faced with the same issue on release build and fixed with preventing the class member name that will be serialized/deserialized obfuscation by proguard.
