Paul,
I guess I'll have to just try a bunch of editors. They have to be able
to fit on the phone as I'm not using a tablet.
I followed your suggestion and got the Mixplorer silver app. It will
take a while to learn to use it. I would indeed like an explanation of
how to remove the security lockdown -- I've already seen messages about
restrictions on importing files which are troubling. Since the Pixel 6
is a Google product, it is updated to the most recent version of android
- it is now at Android 12. I hope they are not going the direction of Apple.
Best regards,
Patrick

There are two issues with files which could cause problems. One is since
Android 9 or 10 you have to give J permission to read files. Since I
installed J903 on to of a version that had already had access, I didn't see
an error after the last J install. Since Android 11, there has been a
security crack down on any access to files in
/storage/emulated/0/Android/data
I've found two file managers which can override this. I use
Mixplorer silver file manager
and I can explain how to remove the security lockdown if you are interested.
The only problem I still have with J on Android 11 and above is the code
that calls external apps calls
android_exec_host
which uses depricated Java code, so browse_j_ and xedit_j_ return without
launching their intended app.

I just recently replaced my old iPhone (a 6 Plus) with a new Google
Pixel 6 Pro.
It seems to be an impressive phone with a great camera. One of my
motivations for not getting a newer iPhone was my desire to escape the
increasingly locked-down Apple philosophy. I had problems moving files
back and forth between my linux computer and the phone. I'm glad to
report that I had no particular difficulty installing J903 on the Pixel
6. The file locations are cumbersome; you need something like
Apath=:
'/storage/emulated/0/Android/data/com.jsoftware.j.android/files/'
in your startup profile. But the good news is that you just need a USB C
cable between your Pixel and computer and you just drag and drop files
to transfer them back and forth. I used to test the speed of J on phones
by inverting a 500 x 500 matrix -- on my old iPhone it took 0.5 sec, but
on this Pixel it's down to 0.046 sec. (Need to use a larger matrix, e.g.
1000 x 1000 -> 0.37 sec.) It took a bit of fussing to install the Dykman
keyboard but now its there and works great. I noticed there was a 2nd
keyboard available but I haven't tried it. How does it differ? I must
say that though I ran J programs on the iPhone, I seldom developed
anything on it. But J903 on this Pixel 6 is so smooth that I've started
writing (short) routines on it and copying them back to the laptop.
My real reason for writing this report is ask for pointers to any
discussions regarding J on android phones. The android OS is completely
new to me. One glitch I encountered was when I modified a J routine with
a text editor I'd installed on the Pixel. I got a strange file read
error. It looked like the editor did something invisible to the file
that ruined the J session -- all my definitions were gone and I had to
kill J and restart. But if I made the file changes on the laptop and
ported the file over, it was fine. Any suggestions for a good text
editor for android? (I'm an old school vi guy, but I've not found a good
plane vi.)
Anyway, I appreciate any pointers of discussions of J on android...
Patrick
