Question

我用android登录facebook，单击登录按钮后，我的进度对话框显示出来，它应该显示图像，电子邮件和totalfriends。但登录后单击按钮时，我的应用程序自动关闭。这个问题已经解决，但是我无法访问/允许json的“生日”和“总数”朋友 创建时

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);



    callbackManager = CallbackManager.Factory.create();

    txtBirthday = (TextView)findViewById(R.id.txtBirthday);
    txtEmail    = (TextView)findViewById(R.id.txtEmail);
    txtFriends  = (TextView)findViewById(R.id.txtFriends);
    imgAvatar   = (ImageView)findViewById(R.id.avatar) ;
    LoginButton loginButton = (LoginButton)findViewById(R.id.login_button);
    loginButton.setReadPermissions(Arrays.asList("public_profile", "email", "user_birthday", "user_friends"));

    loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
        @Override
        public void onSuccess(LoginResult loginResult) {
            mDialog = new ProgressDialog(MainActivity.this);
            mDialog.setMessage("Retrieveing data...");
            mDialog.show();

            String accesstoken = loginResult.getAccessToken().getToken();

            GraphRequest graphRequest = GraphRequest.newMeRequest(loginResult.getAccessToken(), new GraphRequest.GraphJSONObjectCallback() {
                @Override
                public void onCompleted(JSONObject object, GraphResponse response) {
                    mDialog.dismiss();
                    Log.d("response", response.toString());
                    getData(object);

                }
            });

            Bundle parameters = new Bundle();
            parameters.putString("fields", "id,email,birthday,friends");
            graphRequest.setParameters(parameters);
            graphRequest.executeAsync();
        }


    });

}

获取数据

private void getData(JSONObject object) {
    try {
        URL profile_picture = new URL("https://graph.facebook.com/"+object.getString("id")+"/picture?width=250&height=250");

        Picasso.with(this).load(profile_picture.toString()).into(imgAvatar);

        txtEmail.setText(object.getString("email"));
        txtBirthday.setText(object.getString("birthday"));
        txtFriends.setText("Friends : "+object.getJSONObject("friends").getJSONObject("summary").getString("total_count"));

    } catch (MalformedURLException e) {
        e.printStackTrace();
    } catch (JSONException e) {
        e.printStackTrace();
    }
}

错误消息
