I add Prime31 plugin for GooglePlayGameServices but it don't want to authenticate and send an error: "Exception running command on UI thread"
if( GUILayout.Button( "Authenticate" ) )
{
PlayGameServices.authenticate();
}
public static void authenticate()
{
if( Application.platform != RuntimePlatform.Android )
return;
_plugin.Call( "authenticate" );
}
And I did all this tutorial steps.
