Facebook 身份验证失败

Question

我不知道我的代码中出了什么问题，它没有给我任何错误消息。

这是以下代码：SignInFragment

public class SignInFragment extends Fragment implements View.OnClickListener {
private static final String TAG = "email";
private TextView mEmail, mPassword, mHeading, mToRegister, mFckyou;
private EditText eEmail, ePassword;
private Button btnSignin;
private ProgressBar mProgressBar;
//Firebase
private FirebaseAuth mAuth;
private FirebaseAuth.AuthStateListener mAuthListener;
//Facebook
private CallbackManager callbackManager;
private LoginButton loginButton;
@Nullable
@Override
public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.signin_fragment, container, false);
//TextView
mEmail = view.findViewById(R.id.tvEmail);
mPassword = view.findViewById(R.id.tvPassword);
mHeading = view.findViewById(R.id.heading);
mToRegister = view.findViewById(R.id.toRegister);
mFckyou = view.findViewById(R.id.fckyou);
//EditText
eEmail = view.findViewById(R.id.etEmail);
ePassword = view.findViewById(R.id.etPassword);
//Changing the font style of hint
eEmail.setTypeface(Typeface.SANS_SERIF);
ePassword.setTypeface(Typeface.SANS_SERIF);
//Button
btnSignin = view.findViewById(R.id.btnSignin);
//ProgressBar
mProgressBar = view.findViewById(R.id.progressBar);
//Facebook
loginButton = view.findViewById(R.id.login_button);
//Firebase
mAuth = FirebaseAuth.getInstance();
//Progress Bar and Text view = GONE
mProgressBar.setVisibility(View.GONE);
mFckyou.setVisibility(View.GONE);
setupFbAuth();
navigateToReigster();
setupFirebaseAuth();
signInUser();
return view;
}
/*

*/
public void setupFbAuth(){
callbackManager = CallbackManager.Factory.create();
loginButton.setReadPermissions(Arrays.asList("email"));
loginButton.setFragment(this);
loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
@Override
public void onSuccess(LoginResult loginResult) {
handleFacebookAccessToken(loginResult.getAccessToken());
}
@Override
public void onCancel() {
Toast.makeText(getActivity(), "Cancelling...", Toast.LENGTH_SHORT).show();
}
@Override
public void onError(FacebookException error) {
Log.d(TAG, "onError: error" + error.getMessage());
}
});
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {

super.onActivityResult(requestCode, resultCode, data);
//        Fragment fragment = getFragmentManager().findFragmentById(R.id.container);
//        fragment.onActivityResult(requestCode, resultCode, data);
}
private void handleFacebookAccessToken(AccessToken accessToken) {
Log.d(TAG, "handleFacebookAccessToken: " + accessToken);
AuthCredential credential = FacebookAuthProvider.getCredential(accessToken.getToken());
mAuth.signInWithCredential(credential)
.addOnCompleteListener(new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
if (task.isSuccessful()){
Toast.makeText(getActivity(), "Signed in success!", Toast.LENGTH_SHORT).show();
FirebaseUser user = mAuth.getCurrentUser();
updateUI(user);
}else {
Log.d(TAG, "onComplete: authentication_failed");
Toast.makeText(getActivity(), "Authentication Failed", Toast.LENGTH_SHORT).show();
}
}
});
}
private void updateUI(FirebaseUser user) {
FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.replace(R.id.container, new HomeActivity());
ft.commit();
}

Answer 1

更改读取权限如下：

用：

loginButton.setReadPermissions("email", "public_profile");

而不是：

loginButton.setReadPermissions(Arrays.asList("email"));

它对你有用..祝你好运！
