Use the Android sample when you need a native mobile login flow with standards-based OIDC, app-link handling, and a practical starting point for a real app.
The Android sample focuses on a proper native public-client flow. That is the right starting point for direct mobile access. If your product later needs managed profiles or delegated handling, keep those rules in the product identity model rather than trying to encode them into the mobile auth flow itself.
These pages explain the sample on Tuurio's domain. GitHub remains the code host.
