facebook api如何获取电子邮件和电话号码

Question

我实际上正在使用firebase auth。所以我想整合facebook登录以与firebase身份验证并行工作。那么，我的问题是如果没有电子邮件它将获得电话号码，如何从当前用户获取电子邮件和电话号码。这是我的活动代码：

public class SignInActivity extends AppCompatActivity {

  private CallbackManager callbackManager;
    private AccessTokenTracker accessTokenTracker;
    private ProfileTracker profileTracker;
    private FirebaseAuth mAuth;
    private FacebookCallback<LoginResult>callback = new FacebookCallback<LoginResult>() {
        @Override
        public void onSuccess(LoginResult loginResult) {
            Profile profile = Profile.getCurrentProfile();
            nextActivity(profile);
        }

        @Override
        public void onCancel() {

        }

        @Override
        public void onError(FacebookException error) {

        }
    };
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        LoginButton loginButton = (LoginButton)findViewById(R.id.login_button);
        mAuth = FirebaseAuth.getInstance();
        callbackManager = CallbackManager.Factory.create();
        accessTokenTracker = new AccessTokenTracker() {
            @Override
            protected void onCurrentAccessTokenChanged(AccessToken oldToken, AccessToken newToken) {

            }
        };
        profileTracker = new ProfileTracker() {
            @Override
            protected void onCurrentProfileChanged(Profile oldProfile, Profile newProfile) {
                nextActivity(newProfile);

            }
        };
        accessTokenTracker.startTracking();
        profileTracker.startTracking();
        callback = new FacebookCallback<LoginResult>() {
            @Override
            public void onSuccess(LoginResult loginResult) {
                AccessToken accessToken = loginResult.getAccessToken();
                Profile profile = Profile.getCurrentProfile();
                nextActivity(profile);
                Toast.makeText(getApplicationContext(), "Logging in ....",Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onCancel() {

            }

            @Override
            public void onError(FacebookException error) {

            }
        };
        loginButton.setReadPermissions("email", "public_profile","user_friends");
        loginButton.registerCallback(callbackManager, callback);
    }

    @Override
    protected void onResume() {
        super.onResume();
        Profile profile =Profile.getCurrentProfile();
        nextActivity(profile);
    }

    @Override
    protected void onPause() {
        super.onPause();
    }

    @Override
    protected void onStop() {
        super.onStop();
        accessTokenTracker.stopTracking();
        profileTracker.stopTracking();
    }

    @Override
    protected void onActivityResult(int requestCode, int responseCode, Intent intent) {
        super.onActivityResult(requestCode, responseCode, intent);
        callbackManager.onActivityResult(requestCode, responseCode,intent);

    }

    private void nextActivity(Profile profile) {
        if (profile != null) {
            Intent main = new Intent(SignInActivity.this, ProfileActivity.class);
            main.putExtra("name", profile.getFirstName());
            main.putExtra("surname", profile.getLastName());
            main.putExtra("imageUrl", profile.getProfilePictureUri(200, 200).toString());
            startActivity(main);
        }
    }}

编辑：解决方案是电话号码是Facebook api中没有电话号码。因此，为了获得电子邮件ID，我使用了这个解决方案：Facebook Android SDK 4.5.0 get email address
