Hey there @ableflyer welcome to the community!
Most users end up using a custom auth0scheme
as opposed to https
- For example, if I were to set auth0scheme: "demo"
and add the callback url demo://mydomain.us.auth0.com/android/com.auth0.androidsample/callback
to my application settings in my Auth0 dashboard.
Some more on using https (and Android App Links) here:
Hope this helps!
