Java 如何在android中获取Facebook信息

我试图从我的android facebook上获取信息， 我的代码：

loginButton.setReadPermissions(Arrays.asList("email", "user_photos", "public_profile"));
    loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
        @Override
        public void onSuccess(LoginResult loginResult) {
          Toast.makeText(getApplicationContext(),""+loginResult.getAccessToken(),Toast.LENGTH_SHORT).show();
            String accessToken = loginResult.getAccessToken().getToken();
            GraphRequest request = GraphRequest.newMeRequest(loginResult.getAccessToken(), new GraphRequest.GraphJSONObjectCallback() {
                @Override
                public void onCompleted(JSONObject object, GraphResponse response) {
                    Log.i("LoginActivity", response.toString());
                    // Get facebook data from login
                    try {
                        object.get("gender");
                        object.get("email");
                    } catch (JSONException e) {
                        e.printStackTrace();
                    }
                 //   Bundle bFacebookData = getFacebookData(object);
                }
            });
            Bundle parameters = new Bundle();
            parameters.putString("fields", "id, first_name, last_name, email,gender, birthday, location"); // Parámetros que pedimos a facebook
            request.setParameters(parameters);
            request.executeAsync();

        }

有什么解决办法吗？或者此案例与facebook隐私设置有关？

请尝试手动构建登录流。这样您就不会被困在

sdk

上

https://developers.facebook.com/docs/facebook-login/manually-build-a-login-flow

试着替换

loginResult.getAccessToken()

与

Facebook不允许开发人员直接登录“session.getAccessToken”，因为这可能会导致泄漏。您还可以查看此项了解更多信息：

loginResult.getAccessToken()

loginResult.getAccessToken().getToken() .
