我正在尝试在我的应用中使用Google Play游戏服务来实现回合制多人游戏。不幸的是，我在尝试加载Google Play Match中保存的数据时遇到了问题。
这是我的代码摘录：
ByteArrayInputStream bis = new ByteArrayInputStream(match.getData());
ObjectInputStream in = new ObjectInputStream(bis);
Object o = in.readObject();
matchData = (MatchData) o;
以下是我得到的例外情况：
08-29 19:11:02.620 20712-20712/com.cor31.letterbetter E/MainMenu﹕ Error loading match data.

我的项目中没有'h'类，我不知道为什么在readObject期间搜索这个类。谁能解释我做错了什么？感谢。
