Sign in problem

[ItsAntiUp]

I am trying to sign in to Google with this plugin and on editor I got a "exception jni init'd androidjavaclass with null ptr" error. After reading about it, it turns out it doesn't work in unity editor. I built my application on android device and tried again, but it didn't sign in again. I don't know if that was the same error, since there's no way of checking it on an android device. I tried printing some text after certain functions and it turns out the error is somewhere in SigninSampleScript, because on signin method the status bar text "calling signin" appears, and the status bar text after GoogleSignIn.DefaultInstance.SignIn().ContinueWith(OnAuthenticationFinished) doesnt. Help!!!
