StrictMode policy violation Android in Gson

Question

I am getting the following in my application:

StrictMode policy violation: android.os.strictmode.NonSdkApiUsedViolation: Lsun/misc/Unsafe;->theUnsafe:Lsun/misc/Unsafe;
    at android.os.StrictMode.lambda$static$1(StrictMode.java:428)

From what I have seen I need to add disableJdkUnsafe() to my GsonBuilder call. I tried that but I get unknown symbol.

I am using Gson version 2.8.5 but also tried it with 2.8.9. What am I missing?
