New for MIDP 2.0
 | MIDP Specification version 2.0 introduced several new network and communication APIs. The SocketConnection API can be used for reliable connections with servers without the overhead of HTTP. The ServerSocketConnection API allows a device to handle incoming connections. The UDPDatagramConnection API provides for low overhead but unreliable delivery of datagrams and has certain device and network caveats. The CommConnection API defines operations for accessing serial ports on a device if they are available. |
It must be kept in mind that there are many mobile devices that do not provide support for sockets, and therefore the availability of the networking protocols will vary from one device to another. The networks provided by different network operators may also have limitations in the support of specific networking protocols. Also, access to some of the protocols may be prohibited because of the security policies of the device or the network. Close cooperation with the device manufacturer and the network operators' developer programs will be helpful in understanding how to use these APIs and how they may be enabled in particular networks.
