我有以下连接 facebook 的活动

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_facebook);
      mFacebook = SavvyActivityDelegate.get().getFacebook(this);
     if (mFacebook.isSessionValid()) {
         // TODO GET FB ACCESS TOKEN
        } else {
            mFacebook.authorize(this, FacebookConstants.PERMISSIONS, new AppFacebookDialogListener(FacebookActivity.this,mFacebook));
        }

public void onActivityResult(int request, int result, Intent data) {
      super.onActivityResult(request, result, data);
      mFacebook.authorizeCallback(request, result, data);


    }

这是使用的对话侦听器

    public class AppFacebookDialogListener implements Facebook.DialogListener {   
private final Activity activity;  
 private final Facebook facebook;

      public SavvyFacebookDialogListener(Activity activity, Facebook facebook) {
        this.activity = activity;
        this.facebook = facebook;
        Log.d(LogTag.app, "Facebook constructor");    // activity.finish();   }

  @Override   public void onComplete(Bundle values) {
    Log.d(LogTag.app, "Facebook authorization complete!");
    SharedPreferences.Editor editor = PreferenceManager.getDefaultSharedPreferences(activity).edit();
    editor.putLong("fb_access_expires", facebook.getAccessExpires());
    editor.putString("fb_access_token", facebook.getAccessToken());
    editor.commit();   }

  @Override   public void onFacebookError(FacebookError e) {
    Log.e(LogTag.app, e.getErrorType() + ": " + e.getMessage() + " (code: " + e.getErrorCode() + ")", e);   }

  @Override   public void onError(DialogError e) {
    Log.e(LogTag.app, e.getMessage(), e);   }

  @Override   public void onCancel() {
    Log.d(LogTag.app, "Facebook authorization was cancelled");   } }

活动开始时的日志声明

06-06 15:09:19.314: I/ActivityManager(404): 从 pid 17947 开始 u0 {cmp=com.biggu.shopsavvy/.FacebookActivity} 06-06 15:09:19.392: D/ShopSavvy(17947): Facebook构造函数 06-06 15:09:19.400: I/ActivityManager(404): START u0 {cmp=com.facebook.katana/.ProxyAuth (has extras)} from pid 17947 06-06 15:09:19.415: I/ActivityManager （404）：从 pid 15214 开始 u0 {cmp=com.facebook.katana/.ProxyAuthDialog（有附加功能）}

因此，根据日志，对话构造函数被调用，但没有任何回调方法被调用。

如果未安装 facebook 应用程序，则代码工作正常，我完成了回调授权，但代码在具有 facebook 应用程序且用户已登录的设备上表现异常。提前致谢 。
