                // Something went wrong when attempting to connect! Handle errors here
            }
        });

My Client ID is correct, I have used the same Redirect URI in both my dashboard and my code, I have added the SHA1 key but I just don't seem to get it authorized.

It fails at this line: AuthorizationResponse response = AuthorizationClient.getResponse(resultCode, intent); Spotify app seems to open up for a split second (cause I see the loading sign) before getting the AUTHORIZATION SERVICE UNKNOWN error. I have the app and I have logged in using the same ID. Tried on a virtual device and also my personal phone but both of them did not work. Could someone please help? I didn't find anything on the internet so I'm not sure what the issue is.
