In the following https://developer.okta.com/quickstart/#/android/java/generic webpage, there is a section as follows:
Implement Okta Sign-In
Users can sign in to your Android application a number of different ways. The easiest, and most secure way is to use the default login page. This page renders the Okta Sign-In Widget, equipped to handle User Lifecycle operations, MFA, and more.
…which from an Android developer point of view is not helpful. What would be helpful would be a link the Android equivalment of the Sign-In Widget. Perhaps a fragment.
Another further comment to make about the content on this page is that there is not enough content to complete a round trip login page. This is not a quick start if a user gets lost.
