Loading a JSON-Array fails

The JSON-String/Array I get as HTTP-Response is in a single line, like this:

[{
        "haendlerName": "Zielpunkt",
        "shops": [{
            "shopId": 243779,
            "ort": "Wien",
            "strasse": "Erdbergstraße 61",
            "plz": "1030",
            "lat": 48.19867,
            "lon": 16.400263,
            "distance": 0.14937061106081023,
            "openinghours": null
        }],
        "imageLink": "http://images.schnapp.at/images/zielpunkt__e349e2a937b5bf4f78e0fb3063b1fca8.png",
        "account_id": 171619
    }, ...

I´m loading it like this:

HttpClient httpclient = new DefaultHttpClient();
HttpGet httpGet = new HttpGet(url);
response = httpclient.execute(httpGet);
HttpEntity resEntity = response.getEntity(); 
String response2=EntityUtils.toString(resEntity);
JSONArray finalResult = new JSONArray(response2);

EDIT: WORKING VERSION!

HttpClient httpclient = new DefaultHttpClient();
HttpGet httpGet = new HttpGet(url);    
response = httpclient.execute(httpGet);
String json = EntityUtils.toString(response.getEntity());
finalResult = new JSONArray(json);

But in the very last line it crashes, only error I got is a NullPointerException. I checked to content of the tokener, seems to be fine. Also checked to whole input (the String from http-response), it´s a valid JSON-string.

What might be worth mentioning is that the JSONObjects in the main-array also contain a sub-array.

Any Idea what might cause the crash? Or am I doing something completely wrong?

remove BufferedReader, String json and JSONTokener tokener. the try this way

String json = EntityUtils.toString(response.getEntity());
JSONArray finalResult = new JSONArray(json);

EntityUtils.toString reads the content of the Entity and returns it as String

you should replace:

BufferedReader reader = new BufferedReader(new InputStreamReader(response.getEntity().getContent(), "UTF-8"));
    String json = reader.readLine();
    JSONTokener tokener = new JSONTokener(json);
    JSONArray finalResult = new JSONArray(tokener);

with 

String json = EntityUtils.toString(response.getEntity());
JSONArray finalResult = new JSONArray(json);
