• aquaraga: Please add more 'full stops' to your question. It seems more like reading a Virginia Woolf novel.
• user1907906: Please include the code you have tried.
• Chanchal Shelar: Can you please include your code of parsing.
• ayahuasca: I second aquaraga's comment - please try and use punctuation, it will make your question easier to deciper.
• Hot Licks: You'd like to change "project" from a single element to an array? Well, either edit the JSON source to do that, or read it in with a simple parser, navigate through the Maps to "project", and replace the value of "project" with the appropriate List.

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

• Junaid Akhtar: JSONObject["project"] is not a JSONArr it throw this exception
• Junaid Akhtar: I used projectsJsonObject.optJSONArray("project") instead of projectsJsonObject.getJSONArray("project") == null Anyways rest was fine thanks alot
• Chanchal Shelar: @JunaidAkhtar I was expecting exception but at other place, but I'm glad it helped :)

Use Google Gson

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