Choose Your Protocol Wisely
While Java makes it easy to create network connections on any protocol, experience shows that HTTP (and HTTPS) are the most universal.
If you use a custom protocol talking to your own server, there are some
users who will not be able to access your server. Bear in mind that in
some countries, high-speed data (aka 3G) is either not yet available or
is very expensive, whereas GPRS/EDGE is less expensive and more widely
available. Most GPRS service providers only allow HTTP/HTTPS connections,
often through a WAP proxy. That said, there may be things you need to do that
can't be done via HTTP, for example because their protocol demands a different port number (SIP over port 5000, for example). But do try to make HTTP your first choice when you can - you'll include more customers.
