Bill,
I've just been able to get back to JAndroid on my Pixel 8 Pro. I
reinstalled J, this time downloaded directly to the phone, rather than
by USB transfer from my computer. It still took a while to find
JKeyboard. The Pixel has somewhat different file names. I found it under
Settings->System->Keyboard->On-screen Keyboard. Also the variant
JDKeyboard.
My next issue was that .ijs files I'd used on the Pixel 6 had the path
defined as:
Apath=: '/storage/emulated/0/Android/data/com.jsoftware.j.android/files/'
but now it has to be Apath=:
'/storage/emulated/0/Android/data/com.jsoftware.j.beta.android/files/'
With Settings->About phone-> Build number you can enable the USB
developer mode (or something), and then with a cable conection to my
linux computers, I can see and modify all the files on the phone,
especially in
/Android/data/com.jsoftware.j.beta.android/files/ where the J files live.
But here's the rub -- I want to see these files *without* the link to
the computer. The whole idea of running J on the phone is to have it
with you any time/place. I have a program of mine that plots objects
against the background of the stars in the sky, and I want to look at
the plot "in the field". The program generates a plot.pdf file which
goes to j-user/temp/. But the latest versions of the operating system,
Android 13 and 14, block any attempts to view the files in /Android/data
with a "Can't use this folder - to protect your privacy"! This is the
same stuff that drove me from the iPhone to the Pixel :-( But with a lot
of searching or reddit I found there is a file manager in the Play Store
(stupid name) called AV File Manager that uses a workaround called
Shizuku. Using it I can view the plots in /juser. So J on the Pixel 8
Pro is now fully functional.... Until the next release of Android plugs
this workaround and I will be forced to root my lovely phone.

The other issue I mentioned: I have a new System 76 Adder WS laptop
running Pop!_OS with 4 TB of storage. A sweet machine. I have now
installed j9.4 and j9.5 on it. I did have to install the libqt5***
files which were not included in Pop!_OS, but then everything went as
smoothly as could be. I can't say that my J Monte-Carlo codes, which can
run for hours, are much faster than on my Dell xps 13. I imagine will
have to figure out how to start multiple instances of J to make use of
the many cores of this CPU.
Sorry to run on so long, but this could be of use to someone out there.

This is the *JKeyboard* from Michael Dykman. Go to *Settings* >> *Language
& Input* to activate *JKeyboard*. We do not collect your data. Finally
scroll up and select *JKeyboard* in the *default* box.

Bill,
I just re-installed J on my Pixel - amazing: I had been running an ancient
version & this has so much more e.g. viewmat, etc. But I cannot find
anything about the keyboard in settings. I've looked under apps, as well as
more general headings. Any suggestions?
Sent from my Pixel 8 Pro,

You need to go to phone settings and then enable j keyboard. And then it
will be available for your keyboard selection.

Thank you Kenneth,
I just downloaded it to my laptop and transferred to the Pixel 8 via
USB
cable. It works!
Now I need to look around for the j keyboard -- special characters are
a
nuisance on the default. And figure out the correct locations of the
data files and scripts I want to use ...
Best regards, Patrick

Hello all,
While I've not posted for a while, I've been a J user for many
decades.
At present I'm running j9.4 and j9.5 on a mac mini and my Dell xps
13
under Ubuntu 22.04. I generally use jqt. All this is good.
What I'm seeking help with is J for android. Back in Jan 2022, I
acquired a Pixel 6 Pro phone. I installed J on it and have used it
successfully until a few weeks ago, when I upgraded to a Pixel 8 Pro
(seduced by the better camera). Now I want to install J on this
phone,
but the problem is, I don't remember how I installed it. I have the
impression that it was available in the Play Store, but I can't find
it
there now. I see that the files are found on github (thank you
Michael
Dykman), but I haven't used github and am unfamiliar with it - I
can't
believe that's how I installed it (and the J keyboard) on my Pixel
6.
The problem is that there seemed to be no way to copy 3rd party
*apps*
from the Pix 6 to the Pix 8. (I really tried, and failed. Now my
Pixel 6
is gone, traded in).
So I'm asking for help here. Is the J app that I loaded into my Pix
6
a
couple of years ago still out there somewhere, or do I have to
figure
out what to do with all those files on github?
For something completely different, I have on order a System 76
linux
laptop. I'm in need of more computing power. Has anyone out there
installed J under System 76's Pop!_OS (which is basically just
Ubuntu)?
I'll let you know how it goes.
