Firebase 'createCustomToken' not recognized in Android

Question

I'm implementing "login with custom token". I found this snippet of code in the Firebase documentation.

firebaseAuth.createCustomToken(uid)
                            .addOnSuccessListener(new OnSuccessListener<String>() {
                                @Override
                                public void onSuccess(String customToken) {
                                    // Send token back to client
                                }
                            });

I have put this code inside the 'onCreate' method and 'createCustomToken' is not being recognized:

Any idea what I'm doing wrong? Thanks in advance!

Answer 1

you try to mix up the Firebase Admin SDK with the Android SDK. The method createCustomToken is only available at the Admin SDK and not for the Android SDK. The docs for Android can be found here

https://firebase.google.com/docs/auth/android/start/

The Admin SDK can only be used at server side
