Facebook权限-Android移动应用

Question

I am trying to retrieve the info of Facebook user in my android app

This is what I got so far:

MainActivity.java

package com.firstandroidapp;

import java.security.NoSuchAlgorithmException;
import java.util.Arrays;
import java.util.List;

import android.support.v4.app.FragmentActivity;
import android.support.v7.app.ActionBarActivity;
import android.app.Activity;
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.util.Base64;
import android.util.Log;
import android.view.Menu;
import android.view.MenuItem;


import com.facebook.*;
import com.facebook.Session.OpenRequest;
import com.facebook.model.*;
import com.facebook.widget.LoginButton;

import android.widget.TextView;
import android.content.Intent;

public class MainActivity extends FragmentActivity {

    private MainFragment mainFragment;

//   


    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        if (savedInstanceState == null) {
            // Add the fragment on initial activity setup
            mainFragment = new MainFragment();
            getSupportFragmentManager()
            .beginTransaction()
            .add(android.R.id.content, mainFragment)
            .commit();
        } else {
            // Or set the fragment from restored state info
            mainFragment = (MainFragment) getSupportFragmentManager()
            .findFragmentById(android.R.id.content);
        }
    }

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

and the MainFragment.java

        Log.d(TAG, user.getName() + user.asMap().get("email").toString() + user.getProperty("locale") );
        return userInfo.toString();
    }

}

and I only get he Name and e-mail and language and I want more information such as the birthday and pages he/she likes and already added these permissions but for example the birthday returns null any idea what I am doing wrong please ??

Any help would be appreciate it Thanks

Answer 1

Are you sure if the birthday date exists on Facebook profile as well? or they may have set to privacy.
