Google Play - No Authentication

Hi Unity,

I've been stuck on this for the last week and I'm losing my mind. I implemented Google Play Services successfully and without issue (I had done it twice before on other projects). However, I then implemented Ad Mobs successfully and with that build, GPG is not logging me in.

Here's the login code (untouched since it worked):


void Start()
{
PlayGamesPlatform.Activate();
Social.localUser.Authenticate(ProcessAuthentication);
}

void Login()
{
Social.localUser.Authenticate(ProcessAuthentication);
}

public void LoadLeaderboard()
{
if (Social.localUser.authenticated)
{
((PlayGamesPlatform)Social.Active).ShowLeaderboardUI(boardID);
}
else
{
Login();
}
}


I ran logcat and it appears to throw this error when I attempt to Login():

E/Unity ( 8303): Unable to find gpg
I/Unity ( 8303): DllNotFoundException: gpg


Does anyone have any idea what's going on?

Thanks
