android - Facebook 授权访问 token ？

Question

我正在使用教程代码...

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import com.facebook.android.*;
import com.facebook.android.Facebook.*;

public class FacebookSSO extends Activity {

Facebook facebook = new Facebook("ID");

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.splash);

    facebook.authorize(this,new String[] { "offline_access", "publish_stream", "email" },

        new DialogListener() {
        @Override
        public void onComplete(Bundle values) {}

        @Override
        public void onFacebookError(FacebookError error) {}

        @Override
        public void onError(DialogError e) {}

        @Override
        public void onCancel() {}
    });
}

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

    facebook.authorizeCallback(requestCode, resultCode, data);
}

我想知道...一旦用户通过身份验证，我将如何存储访问 token ？在教程中看不到任何提及。

facebook.authorize(this,new String[] { "offline_access", "publish_stream", "email" },

    new DialogListener() {
    @Override
    public void onComplete(Bundle values) {}
    String token=facebook.getAccessToken();  //get access token
    save(token);
    @Override
    public void onFacebookError(FacebookError error) {}

    @Override
    public void onError(DialogError e) {}

    @Override
    public void onCancel() {}
});
}

private void save(String token){
SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(this);
prefs.edit().putString("Token", token).commit();
}

即将其保存在共享首选项中
