问题
I've been implementing Firebase authentication in my Android app and have got it working easily & successfully (signed in debug) for different authentication providers such as Google, however Facebook will not play ball.
I'm consistently receiving a com.google.firebase.FirebaseException when trying to authenticate with Facebook. I'm using the example from the firebase/quickstart auth app on github. As you can see from the output below, the Facebook authentication is successful and a valid access token. however when I pass the token to Firebase to authenticate, the aforementioned exception is thrown.

The Facebook errors page would suggest a problem with the Access Token or Login Status, however the output confirms Log in is successful and the Access Token is fine. I've also confirmed the tokens validity using the Facebook Access Token debugger, entering the token in the output.
I'm hitting brick walls with everything I try, i searched SO thoroughly and tried a lot of different solutions, Googled for hours but not getting anywhere.

Any help appreciated.
回答1:
Can you check your Facebook App ID & Secret settings in Firebase Console are correct? If so, please file a bug for Firebase Authentication at https://firebase.google.com/support/contact/bugs-features/
回答2:
You are most likely entering wrong app credentials in Firebase account. Try copying them once again. Care:- Facebook hides the app secret for you in settings tab. Click on show and then copy it to your firebase account, else it will show the same error.
