My Question or Issue

I am making a simple Android app relying on the Spotify SDK. I tried to make the sample app work from here: https://developer.spotify.com/documentation/android/tutorials/getting-started#prepare-your-environme...

When I run my app (on my actual physical device), neither the onConnected nor onFailure callback method gets triggered once I try to connect to my Spotify App - nothing happens. The authorization request is for sure made, but the control does not get back to my callback methods.

I see no errors in the logs, however, I see a bunch of warnings like:

Unable to resolve Lcom/spotify/protocol/types/HelloDetails; annotation class 949

The fingerprint, client ID and redirect URI are registered on the Developer Dashboard.

Any idea what might go wrong?
