Use Google Gson

JsonParser parser = new JsonParser();
JsonObject o = (JsonObject)parser.parse("{\"a\": \"A\"}");

Please try below code before you pass json to Gson for object conversion, and please let me know if you get any error. Only posibility that I can see is exception at if.

    JSONObject jsonObject = new JSONObject(responseString);
    JSONObject projectsJsonObject = jsonObject.getJSONObject("response").getJSONObject("projects"); 
    if(projectsJsonObject.getJSONArray("project") == null)
    {
        JSONArray jsonArray = new JSONArray();
        jsonArray.put(projectsJsonObject.getJSONObject("project"));
        projectsJsonObject.put("project", jsonArray);

    }
    //Pass jsonObject to Gson
