You can't specify a port number using the Public API. Doing so is a really bad idea, because it encourages developers to hardcode one of the limited (30) set of RFCOMM port numbers.
Try reading the API documentation to see how a UUID is used to look up a port number by SDP record. If you are not connecting to an Android remote device, then you will want to make sure the remote device advertises a simple SDP record with a UUID and port number. Then you can specify that UUID in Android and it will automatically look up the port number for you.
