How to parse json parsing Using GSON in android

Question

I am using GSON for parse Json data. My Json data is below:

{
    "count": "12",
    "colbreak": 1,
    "name": "unary rels",
    "score": "9090",
    "Words": [
        {
            "count": 6,
            "word": "prp_għaċ-",
            "name": "prp_għaċ-",
            "score": 9.1,
            "Words": "kol",
            "seek": 2231297
        }
    ],
    "seek": 0
}

GsonParse.java

public class GsonParse {


 @SerializedName("count")
 public String count;

 @SerializedName("colbreak")
 public String colbreak;

 @SerializedName("name")
 public String count;
 @SerializedName("score")
 public String score;

 @SerializedName("Words")
 public List<Words> mWords = new ArrayList<Words>();

 @SerializedName("seek")
 public String seek;
}

I am using below method to parse this JSON data.

public static <T> ArrayList<T> JsonParse(T t, String response) {
        // convert String into InputStream
        InputStream in = new ByteArrayInputStream(response.getBytes());
        JsonReader reader;
        ArrayList<T> lcs = new ArrayList<T>();
        try {
            reader = new JsonReader(new InputStreamReader(in, "UTF-8"));
            Gson gson = new Gson();

            reader.beginObject();
            while (reader.hasNext()) {

                T cse = (T) gson.fromJson(reader, t.getClass());
                lcs.add(cse);
            }

            reader.endObject();

            /*
             * reader.nextName(); reader.nextString(); reader.nextName();
             * reader.nextString();
             */
            reader.close();
        } catch (UnsupportedEncodingException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

        return (ArrayList<T>) lcs;
    }

I am facing below error.

03-31 10:14:26.968: E/AndroidRuntime(18578): com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_OBJECT but was NAME at line 1 column 73

Try this:

JSONArray jsonarray = jsonObject.getJSONArray("responseData");
Type listType = new TypeToken<ArrayList<AllUsers>>(){}.getType();
List<AllUsers> allUserses = 
    new GsonBuilder().create().fromJson(jsonarray.toString(), listType);

for(AllUsers user: allUserses){
         allUsersDao.insertOrReplace(user);
}
