500KB json file parsed in Android environment

Question

I need to find a faster solution to parse a json file with 500KB. the structure is something like

{
    "response": {
        "code": 0,
        "msg": "OK",
        "searchparameter": {
            "bikes": { … },
            "cars": { 
                 "a":{
                     values[{...}]
                  },
                 "b":{},
                 "c":{},
                 "d":{},
                  "e":{},
           ...

            }
        }
   }
}

I tried gson.fromJson(jsontxt, Response.class), but it causes me like more than 5 mins to parse.. Is there any solutions that is suitable for me? How can I do JSONReader by gson in this case? and would it be helpful? any helps would be appreciated. thanks a lot!!

Do you need to deserialize the entire file? If not, and are looking for something very specific, you could try to read it as a normal file — JRL, Sep 28 '11 at 15:48

Try using a streaming API:

For Gson, https://sites.google.com/site/gson/streaming
Or switch to Jackson: Parsing huge JSON object in Android?

you can use Gson itself but to make it useful try it in using Asyntask so you can tell the user to wait by showing progressDialog
