Why get on the server side will be empty by httpurlconnection inputstream it

If that code is as follows

 public static String requestPost (String linkAddress, int timeout) {
String result = null; 
try {
URL url = new URL (linkAddress); 
setProxy (); 
HttpURLConnection conn = (HttpURLConnection) url.openConnection (); 
conn.setConnectTimeout (timeout * 1000); 
conn.connect (); 
int state = conn.getResponseCode (); 
System.out.println (state); 
System.out.println (linkAddress); 
if (state == HttpURLConnection.HTTP_OK) {
InputStream in = conn.getInputStream (); 
System.out.println ("$ $ $ $ $ $" + in.available ()); 
BufferedReader reader = new BufferedReader (new InputStreamReader (in, HTTP.UTF_8)); 
String line = null; 
while ((line = reader.readLine ())! = null) {
if (result == null) {
result = line; 
} Else {
result + = line; 
} 
} 
} 
} Catch (MalformedURLException e) {
/ / TODO Auto-generated catch block 
e.printStackTrace (); 
} Catch (IOException e) {
/ / TODO Auto-generated catch block 
e.printStackTrace (); 
} 
return result; 
} 

returned by the server state is 200 which is why the visit was a success, but the server does not flow? Flow does exist, I can use the phone to run properly, but with the simulator will not solve? Which setProxy () is set
proxy access through a proxy way

No phone line simulator, then tested using a mobile phone chanting, anyway finally on the phone, not a simulator run.

The problem is that I do not have android phone. . . . . And this little bug module now points assigned my head how to do this? How to connect successfully stream may be empty yet. . . .

Can you take a look at your normal network simulator
Reply:
All functions are normal int state = conn.getResponseCode ();
state = 200
