Good morning.

I passed the all night altering the all files of Android path, and on moment of despair, i copy the Android path of the example code, and this worked!!!

Well, it works. But is not the natural way... the same erro ocorred again...

For solved my problem, the solution its a very very simple.... i noticed the same erro in first initialize of example code, and this is obvioly: in first execute don't exist nothin in AndroidKeyStore..... I make a try{}catch(){} where i init the package and if case a get this exception the app execute the login process.

my solution:

Future<bool> inicializa(context, User user) async {
    try {
      print(await Cognito.initialize());

      if(!await Cognito.isSignedIn()) {
        return false;
      }

      return true;
    } catch (err) {
      print('Initter eror: ${err}');
      return false;
    }
  }
