Android加载数组字符串数组列表EOF Exception

Question

我在我的应用程序中使用ObjectInputStream加载一个ArrayList。奇怪的是，它似乎直到最近一直很好。我看不出是什么导致了它。

以下是涉及的代码片段：

protected ArrayList<String[]> LoadDetailList() {
    InputStream breedin;
    ArrayList<String[]> list = null;
    try {
        breedin = openFileInput("DetailList.ser");
        list = SaveAndLoad.doLoadDetailList(breedin);
    } catch (FileNotFoundException e) {
        System.out.println("Details List not found");
        list = new ArrayList<String[]>();
    }
    Stored.addAllDetails(list);
    return list;
}

@SuppressWarnings("unchecked")
public static ArrayList<String[]> doLoadDetailList(InputStream breedin) {
    ArrayList<String[]> h = null;

    try {

        ObjectInputStream in = new ObjectInputStream(breedin);

        h = (ArrayList<String[]>) in.readObject();

        in.close();
        breedin.close();

    } catch (ClassNotFoundException e) {
        e.printStackTrace();
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }

    return h;
}

任何想法我做错了什么？
