Android question: how to connect to swank, running on android?

swank listens by default only for localhost connections (for a good
reason!). To force it to listen for connections from specific host other
than 127.0.0.1 you have to bind swank::*loopback-interface* to it. For
instance to listen for connections from everywhere on port 4005 you
could use functions from
(defun start-swank ()
(format t "Starting swank server~%")
(let ((swank::*loopback-interface* "0.0.0.0"))
(swank:create-server :port 4005
;; :style nil #|:spawn|#
(defun stop-swank ()
(format t "Stopping swank server~%")
(format t ";; Swank off-line~%"))
Note, that newest slime/swank should support :spawn communication style
just fine with ECL (my PR was merged lately). In that case it should be
enough to call create-server which won't block (note that in the example
above we create separate thread for that).
Since ECL isn't run from CLI but as shared library, it is useful to
define implementation for implementation program (don't remeber for
sure, but I think lack of this caused some problems later)
(defimplementation lisp-implementation-program ()
"Return the argv of the running Lisp process, or NIL."
Hope this helps.
