HttpResponse to string length 0 is returned

Question

I am trying to make an HTTPGet request on a server in an Android APP, but when I change the httpresponse in string, the string is 0 length.

DefaultHttpClient httpclient = new DefaultHttpClient();
HttpGet httpget = new HttpGet("http://"+server+path+"?assets="+URLEncoder.encode(query, "US-ASCII")+"&lt="+localTime+"&to="+timeOffset);
HttpResponse response = httpclient.execute(httpget);
System.out.println("Status"+ response.getStatusLine());
System.out.println("Length "+org.apache.http.util.EntityUtils.toString(response.getEntity()).length());
return org.apache.http.util.EntityUtils.toString(response.getEntity());

Catlog :

I/System.out(22344): StatusHTTP/1.1 200 OK
I/System.out(21737): Length 0

The uri is good,when I copy/past it in a browser I have a result like this :

{"ads":[{"i"...],"pxs":{}}

Does anyone have an idea why my string is empty?

Udpate 1:

    long localTime = System.currentTimeMillis();
    Date date = new Date();
    @SuppressWarnings("deprecation")
    int timeOffset = date.getTimezoneOffset ();

Update 2:

I added this line :

httpget.setHeader("User-Agent", "Mozilla/5.0 (Windows; U; MSIE 9.0; Windows NT 9.0; en-US)");

And now I have this error :

Answer 1

System.out.println("Length "+org.apache.http.util.EntityUtils.toString(response.getEntity()).length());
return org.apache.http.util.EntityUtils.toString(response.getEntity());

You are using it twice. Thats why you get

java.lang.IllegalStateException: Content has been consumed

try setting it to a reference.

            HttpEntity entity = response.getEntity();
            String responseText = EntityUtils.toString(entity);

then do what you have to do with responseText.
