How to serialize and deserialize list of object arrays with flexjson?

Question

does anybody know how to serialize and deserialize a list of object arrays with flexjson?

What I have tried is this:

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

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

Okay .. this works and when I call this webservice I get the following result:

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

In my Android Client I try to deserialize that List of Objects:

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

and I get the following execption:

Help would be appreciated

It looks like the version of the flexjson package you supplied is not compatible with your android version. Did you add this to the libs/ directory of the app?

Flexjson 2.1 is supposed to work on Android according to this (scroll to the bottom).

As org.json package is "built in" into Android, would it be a viable way to just use that package instead?
