Facebook Login works only from API 24 - Local module descriptor class for com.google.firebase.auth not found. error

Question

I added facebook login with firebase authentication on my application, but the login authentication works only from the Android API 24.

When I try to use a lower level API the screen freezes and the application stops working.

It is too high, most of the users have a lower API level.

Indeed I intend to release the application for lower API levels.

The code I am using is bellow.

public class ConfigurationActivity extends Activity {

    Button b_v_mm,b_som;
    LoginButton loginButton;
    CallbackManager callbackManager;

    // [START declare_auth]
    private FirebaseAuth mAuth;
    // [END declare_auth]


    private void handleFacebookAccessToken(AccessToken token) {
        Log.d("FireBase", "handleFacebookAccessToken:" + token);

        AuthCredential credential = FacebookAuthProvider.getCredential(token.getToken());
        mAuth.signInWithCredential(credential)
                .addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
                    @Override
                    public void onComplete(@NonNull Task<AuthResult> task) {
                        if (task.isSuccessful()) {
                            // Sign in success, update UI with the signed-in user's information
                            Log.d("FireBase", "signInWithCredential:success");
                            FirebaseUser user = mAuth.getCurrentUser();
                            //updateUI(user);
                        } else {
                            // If sign in fails, display a message to the user.
                            Log.w("FireBase", "signInWithCredential:failure", task.getException());
                            //Toast.makeText(FacebookLoginActivity.this, "Authentication failed.",
                             //       Toast.LENGTH_SHORT).show();
                            //updateUI(null);
                        }

                        // ...
                    }
                });
    }

    // [START on_start_check_user]
    @Override
    public void onStart() {
        super.onStart();
        Log.d("FireBase", "onStart");
        // Check if user is signed in (non-null) and update UI accordingly.
        FirebaseUser currentUser = mAuth.getCurrentUser();
        //updateUI(currentUser);
    }
    // [END on_start_check_user]

What can I do to lower the API level required?

Answer 1

Try resync your client with your Firebase app, and add again the .json file.

In android studio 2.3 just click on tools>firebase and in the assistant check if your app is connected to.

And also make sure that the package name is correct in both facebook developers account and firebase console.

Use the latest Firebase library

Can you check your Google Play Services version?

The Android device should have Google Play services 9.0.0 or later

One of the reason for this problem could be, your Sign In Method inside Firebase > Auth Dashboard might be disabled
