有人知道如何使用flexjson序列化和反序列化对象数组列表吗?

我试过的是:

@GET 
@Produces(MediaType.APPLICATION_JSON)
@Path("/getAllGeoData")
public String getAllGeoData(){
    List<Object[]>l = geoMapService.getAllGeoData();

    return new JSONSerializer().serialize(l);
}

好的..这很有效,当我调用这个web服务时,我得到以下结果:

[[50.0830292,8.2387331],[50.0830292,8.2387331],[50.0752003,8.2397125]]

在我的Android客户端中,我尝试反序列化该对象列表:

List<Object[]> l=new  JSONDeserializer<List<Object[]>>().deserialize(jsonstring);

我得到以下的执行:

看起来您提供的flexjson软件包的版本与您的Android版本不兼容。您是否将此添加到应用程序的libs /目录中?

Flexjson 2.1应该可以根据to this在Android上运行(滚动到底部)。

由于org.json包是&#34;内置&#34;进入Android,是否只是使用该软件包的可行方式?
