java.lang.NoSuchMethodError no non-static method with name='getStatusCode' signature='()I' in class Ljava.lang.Object;

Question

Really struggling with this error for our unity game. Our game has firebase and GPGS which we suspect is related but not sure where to look for this.

Anybody had similar or can give us some pointers as to where to look or what is happening. (i can't reproduce on my android devices)

Answer 1

Try this:

1. put your jar|arr librarys into Unity Path:Assets/Plugins/Android/ .
2. Change Unity Configs. Build Settings --> Build System ，select Internal .

When I select Gradle, I had the same error you had, and don't know why. I even had a gradle file in the path.
