JsonDeserializer 无法反序列化对象

Question

我已经开始在 Honeycomb 上测试应用程序，并收到以下错误消息：

com.google.gson.JsonParseException: The JsonDeserializer com.google.gson.DefaultTypeAdapters$CollectionTypeAdapter@408424f0 failed to deserialized json object
[{"type":"location","id":1,"name":"Manukau Heights","description":null,"children":[]},{"type":"location","id":2,"name":"Manukau Central","description":null,"children":[]},{"type":"location","id":3,"name":"Manukau City","description":null,"children":[]},{"type":"location","id":4,"name":"Redoubt North","description":null,"children":[]},{"type":"location","id":5,"name":"Redoubt South","description":null,"children":[]},{"type":"location","id":6,"name":"Goodwood Heights","description":null,"children":[]},{"type":"location","id":7,"name":"Totara Heights","description":null,"children":[]},{"type":"location","id":8,"name":"Totara Park","description":null,"children":[]}]
given the type com.google.gson.ParameterizedTypeImpl@8a7527

当使用 Gson 和 fromJson

MyLocation[] locations = gson.fromJson(in, MyLocation[].class);

MyLocation 时，它看起来像这样：

private String name = "";
private String type = "";
private String id;
private List<MyLocation> children = new ArrayList<MyLocation>();
private String description = "";

我主要担心的是，这在 Honeycomb 之前的许多设备上都能完美运行。我尝试过以下方法： Nexus 1 2.3.4， HTC Hero 2.1 更新 1， 戴尔场地 2.2.2， 戴尔 Streak 7" 2.2.2, Garmin Asus 2.1 update 1

，我没有看到任何异常（并且数据导入看起来很完美）。

任何人都可以提供可能会有所不同的建议以及我如何管理它吗？

（我遇到了类似的 XML 解析方式不同的问题，但我找到了解决方法，将其转至 Honeycomb）

问候， 朱利叶斯.

我改用 Jackson，这个问题就消失了。所以这并不能解释原来的问题，但似乎有效。
