android - Facebook 登录失败， "something went wrong"

Question

我正在制作一个使用 Facebook 登录的应用程序。我让登录独立工作，但现在将它与我的其他 Activity 集成时，它不会登录。它带有错误消息“抱歉，出了点问题。我们正在处理它，我们会尽快修复它”，然后我按下回它正确地说登录已被取消，所以我知道它做到了那么远。任何人都可以看到有什么问题吗？我正在用我的家用电脑和笔记本电脑做同一个项目。这是否会以某种方式与我的 strings.xml 中的 facebook-id 混淆？

MainActivity.java

package com.example.nan.spymap;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.TextView;

import com.facebook.CallbackManager;
import com.facebook.FacebookCallback;
import com.facebook.FacebookException;
import com.facebook.FacebookSdk;
import com.facebook.login.LoginResult;
import com.facebook.login.widget.LoginButton;

public class MainActivity extends Activity {

    private CallbackManager callbackManager;

    private TextView info;
    private LoginButton loginButton;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        FacebookSdk.sdkInitialize(getApplicationContext());
        callbackManager = CallbackManager.Factory.create();

        setContentView(R.layout.activity_main);



        setContentView(R.layout.activity_main);
        info = (TextView)findViewById(R.id.info);
        loginButton = (LoginButton)findViewById(R.id.login_button);

        loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
            @Override
            public void onSuccess(LoginResult loginResult) {
                startActivity(new Intent(MapActivity.this, MapActivity.class));

            }

            @Override
            public void onCancel() {
                info.setText("Login attempt cancelled.");
            }

            @Override
            public void onError(FacebookException e) {
                info.setText("Login attempt failed.");
            }
        });

    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        callbackManager.onActivityResult(requestCode, resultCode, data);
    }
}
