Sample scene is crashing on Android when doing any function

[phedg1]

Clicking Sign In, Sign In (Games), Sign In Silently, Sign Out or Disconnect causes the app to crash. This is on an Android build, I haven't tried iOS yet. This is the log captured in adb logcat when I pressed the "Sign In" button.

I can't understand the log after #14. #14 corresponds to the following line:

    /// <summary>
    /// Starts the authentication process.
    /// </summary>
    /// <remarks>
    /// The authenication process is started and may display account picker
    /// popups and consent prompts based on the state of authentication and
    /// the requested elements.
    /// </remarks>
    public Future<GoogleSignInUser> SignIn() {
      IntPtr nativeFuture = GoogleSignIn_SignIn(SelfPtr()); // THIS LINE
      return new Future<GoogleSignInUser>(new NativeFuture(nativeFuture));
    }

I have already removed "src" from the start of the .aar files, this as far as I've gotten on Android.

The mistake was mine. Because it was taking so long to compile my project to test on Android I created a new project that just contained the SDK and the sample scene. What I forgot is that the web client id was part of a credential generated from my SHA1 and package name. When I was building my test project I was leaving it unsigned with a different package name. After I remedied this it worked perfectly.
