String jsontext = new String(buffer); 
JSONArray entries = new JSONArray(jsontext); 
x = "JSON parsed.\nThere are [" + entries.length() + "]\n\n";

OK, your code seems to be reading all the HTTP including the headers. That is why yours does not start with "[".

Here is the code that I use to get back the string content of an HTTP GET:

public static String getStringContent(String uri) throws Exception {

    try {
        HttpClient client = new DefaultHttpClient();
        HttpGet request = new HttpGet();
        request.setURI(new URI(uri));
        HttpResponse response = client.execute(request);
        InputStream ips  = response.getEntity().getContent();
        BufferedReader buf = new BufferedReader(new InputStreamReader(ips,"UTF-8"));

        StringBuilder sb = new StringBuilder();
        String s;
        while(true )
        {
            s = buf.readLine();
            if(s==null || s.length()==0)
                break;
            sb.append(s);

        }
        buf.close();
        ips.close();
        return sb.toString();

        } 
    finally {
               // any cleanup code...
            }
        }
