I just tried it on my machine and it compiled without any problems after I took out the dependencies I didn't have access to. I never got the error you mentioned. Maybe it's referring to something else? Cut everything out of your project (maybe make a new one) except the onResult function you believe may be the cause and see if you still get the error. I suspect you won't. Good luck!
