I can not speak for John here, but when I started APRSdroid, I was not
able to find anything even remotely usable from a Java app, so I started
with my own parser, which was later on replaced by java-aprs-fap [1],
the Java port of the Perl parser. javAPRSlib is based on the
java-aprs-fap code, and both John and I try hard to make it usable as a

It does not include message segmentation and timeout handling. The
former should be possible to add without too much work if the need
arises, and the latter should be implemented at application level anyway
(timeout handling always depends on what kind of I/O interface you use).

As for non-Java solutions, there is of course the excellent Perl
module maintained by Hessu [2], which is in use on aprs.fi.
