Hi Troy,
I did not re-attempt to fix the shared data path idea for Android >= 11.
Since Google introduced their scoped storage model ... I gave up on it.
On Android versions <= 10, I use the SWORD path /sdcard/Documents/sword.
On versions >= 11, I store everything in the internal app directory, and
therefore there is no shared data path anymore.
If you happen to figure out a reliable solution for >= 11 and the new
Scoped Storage model, I'd be happy to learn.
For >= 11 I am thinking about introducing a Cloud sync feature for the
sword directory. This could then work with Dropbox and maybe also OneDrive.
Best regards,
Tobias
PS: I had a long summer break this year and was not very active on this
mailing list. Hopefully my participation will increase again now.

Hi Tobias and others with Android SWORD apps.
I am trying to bundle up a new version of Bishop for Android with the
some exciting improvements in the libsword (I'll post another email
about those, Lord willing, soon), and I would like to check on the
latest status for a shared sword path for us.
I have tried again to read about the current ways for apps to share
data and am still unclear what is allowed, without performing experiments.
Tobias, where did you end up with your data path? I'll do some
investigations with the latest versions of Android images available
from Google and see where the current logic in Bishop creates data
files and report back.
Hope you are all having a wonderful weekend!
Glory to God for salvation in Jesus! And thanks to Him for life and a
warm bed and a roof over our heads and relative peace. Many don't
have those things.

Hi Tobias,
So, I did a bunch of reading when choosing this location and couldn't
find anything that specifically listed which folders where standard
"top level" folders under /sdcard, only that the changes to the API
in newer versions of Android prevented creation of top level folders
under /sdcard. This article suggested to use 'Music':

I didn't think Music was appropriate for us, but Iooked on my
developer images from Google on the latest version of Android and a
few versions back (I only need to go back as far as until Android
still lets me store to /sdcard/sword, because I try that next if
/sdcard/Documents/sword fails), and on my physical phone, and they
all had /sdcard/Documents/ available.
I am open to better suggestions.
Again, to sum up where I understand things now:
Android, pre-10 lets us store to /sdcard/sword
Android 10 was kind of a mess and wanted everyone to use the new
storage api instead of file paths but still allowed /sdcard/sword
Android 11 and later, Google recanted because of pressure from the
community and settled on: file path are officially blessed again, but
no top level folders created by apps under /sdcard, so we need to
choose a folder.
/sdcard/Documents/sword seemed to exist on all versions of Android I
checked, later than the versions which still supported /SD
card/sword, so I settled with the logic:
Try in this order to test write access to:
/sdcard/Documents/sword
/sdcard/sword
[private unshared app storage]/sword
That's my best attempt. If you have a better suggestion, I am all ears.

Hi Troy,
I can certainly consider /sdcard/Documents as a new base also for
Ezra (haven't tried it yet).
I just did a quick search and I didn't find any official Android
documentation on that particular filesystem path. Is there
something you can point me to?
Best regards,
Tobias

Thanks Michael, yes, I also feel we need to not swim against the
Google flow. The problem is that the Google flow seems to turn
at each new release of Android. Be assured, my goal is to find
a common means for us to share a single install of SWORD modules
and to do it the way Google wants and for as many versions of
Android as practical.
Tobias,
I've had no trouble writing to /sdcard/... from our C++ code, as
long as I don't write to the root of /sdcard/. My change from
/sdcard/sword to /sdcard/Documents/sword/ works fine on Android 11.
Can you give /sdcard/Documents/sword/ a try? You can grab my
exact C++ code from the cordova plugin if you have trouble.
https://crosswire.org/svn/sword/trunk/bindings/java-jni/jni/swordstub.cpp
static void init(JNIEnv *env);

Dear Troy,
We should certainly align on the directories and keep it simple.
However, starting from Android 11 Google makes it really hard
for us due to the "Scoped Storage" concept, see
https://developer.android.com/about/versions/11/privacy/storage
I couldn't figure out a way to write to /sdcard any more in my
C++ context on Android 11.
As a consequence at the moment I am not using /sdcard from
Android 11 anymore, but only the private app folder.
For Android < 11 I am using */sdcard/sword*, but for Android >=
11 I have completely disabled this including the permissions
request for WRITE_EXTERNAL_STORAGE.
I wonder whether there is still any way to still use /sdcard/*
in Android >= 11 in the C++ context ... I haven't found a
solution yet and it seems rather complicated.
Best regards,
Tobias

Dear all,
I've been updating Bishop to work on newer versions of Android and have
found that we are running into problems trying to create the
"Nonstandard top-level folder" 'sword' at the root of the common storage
folder.
Tobias, I know a while back you mentioned that you had to update Ezra
for Android recently, but it has been a long while since we talked about
it and I'd like to know if you've had any updated thoughts on what
you're doing there.
Any other mobile Android devs have any thoughts.
For now, I have updated our cordova plugin (and thus Bishop) to check
and if possible use paths in this preferred order:
"/sdcard/Documents/sword"
"/sdcard/sword"
((android.app.Application)
app).getApplicationContext().getFilesDir().getAbsolutePath();
And we are augmenting modules from AndBible:
"/sdcard/Android/data/net.bible.android.activity/files"
... but I'd prefer not to do this any longer, once we all agree and
implement storing files in a common location.
Any thoughts?
Troy
