Java Facebook共享没有发生？

我正在开发一个应用程序，在其中我正在进行facebook共享。我可以成功地分享，但只有在我没有安装facebook应用程序时。当我安装facebook应用程序并尝试共享时，它要求登录，当我登录时，我会看到以下对话框“我的应用程序希望访问您的公共配置文件和朋友列表”。当我点击“OK”按钮时，它正在进行一些处理，然后再次出现在我的应用程序上，但没有任何内容可以共享。 请帮帮我。 这是我的密码：-

  public class BaseFbTwitterShareAppActivity extends Activity {
private UiLifecycleHelper uiHelper;
public Session.StatusCallback statusCallback = new SessionStatusCallback();

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

    uiHelper = new UiLifecycleHelper(this, statusCallback);
    uiHelper.onCreate(savedInstanceState);
}


@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    uiHelper.onActivityResult(requestCode, resultCode, data,
            new FacebookDialog.Callback() {
                @Override
                public void onError(FacebookDialog.PendingCall pendingCall,
                        Exception error, Bundle data) {
                }

                @Override
                public void onComplete(
                        FacebookDialog.PendingCall pendingCall, Bundle data) {
                    // Log.i("Activity", "Success!");
                }
            });
}

    super.onResume();
    uiHelper.onResume();

    super.onSaveInstanceState(outState);
    uiHelper.onSaveInstanceState(outState);

我得到了答案，代码是完美的，但我的哈希键不匹配。我不知道为什么没有facebook应用程序就可以分享。但正如我所说的，这两种情况下都是共享的。 -当我有facebook应用程序时。 -当我没有facebook应用程序时
