Question

我试图制作https://developers.facebook.com/docs/android/getting-started/中提及的应用，但我遇到了一个问题。我可以运行应用程序并使用我的FB帐户登录，但我无法在Facebook上获取我的名字。当我试图得到我的名字时，这是错误：

07-09 00:36:12.275: D/Request(28372): Warning: Sessionless Request needs token but missing either application ID or client token.

我认为问题在于身份验证或与访问FB数据库相关的一些权限。任何意见将不胜感激..

这是我正在处理的代码：

package com.example.firstface;

import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;

import android.content.Intent;
import android.content.pm.PackageInfo;
import android.content.pm.PackageManager;
import android.content.pm.PackageManager.NameNotFoundException;
import android.content.pm.Signature;
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.util.Base64;
import android.util.Log;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.TextView;

import com.facebook.Request;
import com.facebook.Response;
import com.facebook.Session;
import com.facebook.SessionState;
import com.facebook.model.GraphUser;

public class MainActivity extends ActionBarActivity {

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

        // start Facebook Login         
        Session.openActiveSession(this, true, new Session.StatusCallback() {

          // callback when session changes state
          @Override
          public void call(Session session, SessionState state, Exception exception) {
            if (session.isOpened()) {
                Log.d("Info : ", session.getApplicationId());
              // make request to the /me API
              Request.newMeRequest(session, new Request.GraphUserCallback() {

                // callback after Graph API response with user object
                @Override
                public void onCompleted(GraphUser user, Response response) {
                  if (user != null) {
                    TextView welcome = (TextView) findViewById(R.id.welcome);
                    welcome.setText("hello " + user.getName() + "!");
                  }
                }
              }).executeAsync();
            }
          }
        });
    }

    @Override
      public void onActivityResult(int requestCode, int resultCode, Intent data) {
          super.onActivityResult(requestCode, resultCode, data);
          Session.getActiveSession().onActivityResult(this, requestCode, resultCode, data);
      }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();
        if (id == R.id.action_settings) {
            return true;
        }
        return super.onOptionsItemSelected(item);
    }
}

Answer 1

从Fragment中删除onActivityResult，然后在Activity页面上添加方法

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    Session.getActiveSession().onActivityResult(this, requestCode, resultCode, data);
}

它对我有用!!!!!

Answer 2

这对我有用：

       <string name="app_id">999999999999999</string>
    <meta-data
        android:name="com.facebook.sdk.ApplicationId"
        android:value="@string/app_id" />

Android Facebook SDK＆＃34;无会话请求需要令牌，但缺少应用程序ID或客户端令牌＆＃34;
