My application accesses internet to download a file from the given link. I am using my institute’s internet connection which uses proxy settings.

For my application to be able to download the file from internet I need to open my internet browser, give the username and password for connection and keep the browser running, only then is my application able to download the complete file, if I don’t do these things my application runs normally and creates a file in the desired place but shows the file size to be zero, which is most likely because it is unable to connect to the internet directly.

How can I make my application show a dialog to me asking for the username and password to connect to internet, if it is unable to.

Thanks 🙂

    When you create the connection object through which the file transfer will be effected, you must specify that you are using whatever form of authentication credentials that the proxy is expecting. I don’t know what you’d do in Java for Android, but in .NET I do this:

      LogHandler.Log(LogHandler.LogType.Debug, "Configure proxy credentials");

  // Proxy address and port
  ec2Config.ProxyHost = ConfigurationManager.AppSettings["LocalProxyHost"];
  ec2Config.ProxyPort = Convert.ToInt32(ConfigurationManager.AppSettings["LocalProxyPort"]);

  // Create a dummy webrequest so we can set proxy credentials (to stop the proxy spitting 407s at us)
  HttpWebRequest dummyRequest = (HttpWebRequest)WebRequest.Create(ec2Config.ServiceURL);
  dummyRequest.Proxy.Credentials = CredentialCache.DefaultCredentials;

  #pragma warning disable 168
  HttpWebResponse myHttpWebResponse = (HttpWebResponse)dummyRequest.GetResponse();
  #pragma warning restore 168
