Hi again, so, the progress of the new android REPL is going well, it already runs Quicklisp and can start swank, and right there I'm stuck now: How does one connect from the local computer to the android device, which is running the SLIME-listener? They are connected via USB, and the device is /not/ rooted. Since this is certainly of public interest, I ask here, thanks for any help! Below the link to the current APK of the REPL (you'll need android version >= 4.1, API >= 16): http://lights-of-holiness.eu/tmp/repl.apk After launching the app, do (there is currently no feedback of the progress, sorry): (quicklisp) ; should take less than a minute, with a fast internet connection (start-swank) ; same as above (needs to byte-compile all 'contribs') If I run: (mp:all-processes) it lists the running "SLIME-listener" process, so it seems to work... Thanks for any help! Paul
