Http connection timeout on Android not working

Question

I'm writing an application that connects to a webservice and I don't want it to wait too long if it can't get a connection. I therefore set the connectionTimeout of the httpparams. But it doesn't seem to have any effect whatsoever.

To test I turn of my WLAN temporarily. The application tries to connect for quite some time (way more than the 3 seconds I want) and then throws an UnknownHostException.

Here is my code:

try{     HttpClient httpclient = new DefaultHttpClient();     HttpParams params = httpclient.getParams();     HttpConnectionParams.setConnectionTimeout(params, 3000);     HttpConnectionParams.setSoTimeout(params, 3000);      httppost = new HttpPost(URL);     StringEntity se = new StringEntity(envelope,HTTP.UTF_8);     httppost.setEntity(se);     //Code stops here until UnknownHostException is thrown.     BasicHttpResponse httpResponse = (BasicHttpResponse) httpclient.execute(httppost);      HttpEntity entity = httpResponse.getEntity();     return entity;  }catch (Exception e){     e.printStackTrace(); } 

Anyone have any ideas what I missed?

Answer 1

Try to do it this way:

HttpPost httpPost = new HttpPost(url); StringEntity se = new StringEntity(envelope,HTTP.UTF_8); httpPost.setEntity(se);  HttpParams httpParameters = new BasicHttpParams(); // Set the timeout in milliseconds until a connection is established. int timeoutConnection = 3000; HttpConnectionParams.setConnectionTimeout(httpParameters, timeoutConnection); // Set the default socket timeout (SO_TIMEOUT)  // in milliseconds which is the timeout for waiting for data. int timeoutSocket = 3000; HttpConnectionParams.setSoTimeout(httpParameters, timeoutSocket);  DefaultHttpClient httpClient = new DefaultHttpClient(httpParameters); BasicHttpResponse httpResponse = (BasicHttpResponse)  httpClient.execute(httpPost);  HttpEntity entity = httpResponse.getEntity(); return entity; 

You then can catch a possible ConnectTimeoutException.
