If you just want to get status, try like this:

JSONObject jsonObject = new JSONObject(jsonString);
String status = jsonObject.optString("status");

if you want to parse whole data, I would recommend you to use Gson.

For easy JSON parsing/manipulating/etc use GSON library at android. Example you can make custom objects and straight create new instance of your custom object from parsing and then just check fields or whatever you need to do.

CustomObject object= gson.fromJson(JSON, CustomObject.class);
if(object.bannerPath != null) {
  //Do something
}

Here is the GSON in Github

and here for GSON tutorial

//editing Rohit Arya Code little bit

JSONObject jsonObject = new JSONObject(jsonString);
String status = jsonObject.optString("status");
if(status.equalIgnorecase("400")){
    try {
                    JSONObject jsonObject=new JSONObject("yourResponse");
                   jsonObject1=jsonObject.getJSONObject("response");
                    JSONArray jsonArray=jsonObject1.getJSONArray("data");
                    JSONObject jsonObject2;
                    for(int i=0;i<jsonArray.length();i++){
                        JSONObject c = jsonArray.getJSONObject(i);
                       String banner_name=c.getString("banner_name");
                        Log.e("banner_name",banner_name);
                    }
                } catch (JSONException e) {
                    e.printStackTrace();
                }
}else{
