我使用适用于 Android 3.0 的 Facebook SDK 我想获取用户的照片并在我的应用程序中显示。参考文档，登录成功。我试着拿到这张专辑。

我尝试了两种方法fql和graph api。

    graph_or_fql = "fql";
    if (graph_or_fql.equals("fql")) {
        String query = "SELECT aid, cover_pid, name, size, visible, object_id FROM album WHERE owner = "
                + userId;
        Bundle params = new Bundle();
        params.putString("method", "fql.query");
        params.putString("query", query);

        mAsyncRunner.request(null, params,
                new PhotosRequestListener());
    } else {
//      Bundle params = new Bundle();
//      params.putString("fields", "name, aid, size");
//      mAsyncRunner.request("me/photos", params,
//              new PhotosRequestListener());
        mAsyncRunner.request("me/album",
                new PhotosRequestListener());
    }

    /*
     * callback after friends are fetched via me/friends or fql query.
     */
    public class PhotosRequestListener extends BaseRequestListener {

        @Override
        public void onComplete(final String response, final Object state) {
            dialog.dismiss();
            Log.d("tag", "response: " + response);
            try {
                if (graph_or_fql.equals("fql")) {
                    jsonArray = new JSONObject(response).getJSONArray("data");
                    // jsonArray = new JSONArray(response);
                    // JSONObject jsonObj = new JSONObject(response);
                    // jsonArray = new JSONArray(jsonObj.getString("data"));
                } else {
                    jsonArray = new JSONObject(response).getJSONArray("data");
                }
            } catch (JSONException e) {
                showToast("JSONError: " + e.getMessage());
                e.printStackTrace();
                return;
            }
            gridView.setOnItemClickListener(MainActivity.this);
            gridView.setAdapter(new GridViewAdapter(MainActivity.this));
        }

        public void onFacebookError(FacebookError error) {
            dialog.dismiss();
            Toast.makeText(getApplicationContext(),
                    "Facebook Error: " + error.getMessage(), Toast.LENGTH_SHORT)
                    .show();
        }
    }

但全是错误。

fql 错误消息：“error_msg”：“会话密钥无效或不再有效”

我不明白，因为什么原因。帮帮我，谢谢。
