Question

Hi my application requesting some data from server , application shows Dialog to the user till application receives result but in some cases application doesn’t receive any response and no timeout occurs and dialog remains forever on the screen.

Following below is code for HttpClient.

    HttpParams params = new BasicHttpParams();
    HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);  
    HttpProtocolParams.setContentCharset(params, HTTP.UTF_8);  
    HttpProtocolParams.setUseExpectContinue(params, true);  
     // Turn off stale checking. Our connections break all the time anyway,
    // and it's not worth it to pay the penalty of checking every time.
    HttpConnectionParams.setStaleCheckingEnabled(params, false);

    // Default connection and socket timeout of 30 seconds. Tweak to taste.
    HttpConnectionParams.setConnectionTimeout(params, 5*1000);
    HttpConnectionParams.setSoTimeout(params, 30*1000);
    HttpConnectionParams.setSocketBufferSize(params, 8192);

    ConnManagerParams.setTimeout(params, 5 * 1000);
    ConnManagerParams.setMaxConnectionsPerRoute(params, new ConnPerRouteBean(50));
    ConnManagerParams.setMaxTotalConnections(params, 200);

    // Sets up the http part of the service.
    final SchemeRegistry supportedSchemes = new SchemeRegistry();

    // Register the "http" protocol scheme, it is required
    // by the default operator to look up socket factories.
    final SocketFactory sf = PlainSocketFactory.getSocketFactory();
    supportedSchemes.register(new Scheme("http", sf, 80));
    supportedSchemes.register(new Scheme("https", SSLSocketFactory.getSocketFactory(), 443));  
    final ThreadSafeClientConnManager ccm = new ThreadSafeClientConnManager(params,
            supportedSchemes);

    DefaultHttpClient httpClient = new DefaultHttpClient(ccm, params);`

please specify the error or some other code suggestions if something is wrong in it.

advice:

when the dialog show, need send delay message to handler, when receive the delay message, dismiss the dialog and cancel request

Hanlder.sendEmptyMessageDelayed(what,delay_time)

HttpUriRequest.abort to cancel request

the delay time you can assume the timeout or whatever you think the longest time.
