Because of this it is not getting redirected to the Authenticator app. When i Downgrade again to package version 4.4.0 everything runs smooth.

I'm going to guess (please correct me if I'm wrong here) that this is meant for the Adal for Android team. I'll be closing this here. If this is still an issue and you do believe it is applicable to the JavaScript library, please comment again here, else this issue should be brought up with the Android team.
