Network prompts

Destination Network or Internet Access Point for connection is selected using the following criteria when the MIDlet opens a network connection:

  1. Use IAP Info API and Generic Connection Framework

    Nokia IAP Info API gives applications access to Internet Access Point (IAP) and Destination Network (SNAP) related information. For more information, see IAP Info API description.

  2. Use MIDlet suite default Access Point (IAP) if it is defined in Application Manager.

    The end user can define the Access Point manually via MIDlet suite settings in Application Manager. This Access Point is then automatically used for all network connections.

  3. Prompt user for Destination Network (SNAP) or Internet Access Point (IAP) selection. If phone's Default Connection is defined, it is used instead and user is not prompt at all.

If a network connection has been successfully opened and the operation on that opened connection fails (for example if the device is out of network coverage of the selected Internet Access Point), the user is not prompted to select Destination Network (SNAP) or Internet Access Point (IAP) until the next connection is opened.

A MIDlet can avoid additional IAP selection prompts when it reconnects to same host by storing resolved IP address in a variable, such as in the code snippet below:

String url = "socket://host.com:79";
String address = "";
 
SocketConnection con = (SocketConnection)Connector.open(url);
address = con.getAddress();
 
// IP address should be used in following connections
// instead of host name

This workaround can be used with socket, SSL, HTTP and HTTPS connections.
