[Xposed Framework Modules] stormy1777:
Oh dear.. final update for time being, hopefully will bring a bit of clarity :)

Seems like nothing works, even basic customization, looking at logcat while using kmod/fwa, seeing many many such:

10-25 12:46:23.230 21117 21117 W stat-save: type=1400 audit(0.0:116799): avc: denied { search } for name="kmod.xposed" dev="mmcblk0p60" ino=904802 scontext=u:r:untrusted_app:s0:c27,c257,c512,c768 tcontext=u:object_r:app_data_file:s0:c162,c256,c512,c768 tclass=dir permissive=0

ok, so, that's SELinux, but tried that already, it did not fix the wa_contacts table not found.. poking around, found this directory in kmod.xposed/database, that has, what appears to be an EMPTY wa.db:

:/data/system # cd /data/user/0/kmod.xposed/databases/
:/data/user/0/kmod.xposed/databases # ls -l wa*
-rw------- 1 u0_a162 u0_a162 4096 2019-10-25 11:32 wa.db
-rw------- 1 u0_a162 u0_a162 32768 2019-10-25 11:39 wa.db-shm
-rw------- 1 u0_a162 u0_a162 16512 2019-10-25 11:32 wa.db-wal
:/data/user/0/kmod.xposed/databases # strings wa.db
SQLite format 3
:/data/user/0/kmod.xposed/databases # rm -f *

without much thought, removed all of these, and instantly it copied a good copy!! White/black list LOADED just fine, no crashes...

:/data/user/0/kmod.xposed/databases # ls -l
total 548
-rw------- 1 u0_a162 u0_a162 507904 2019-10-25 12:32 wa.db
-rw------- 1 u0_a162 u0_a162 32768 2019-10-25 12:32 wa.db-shm
-rw------- 1 u0_a162 u0_a162 4152 2019-10-25 12:32 wa.db-wal

So "issues" could be roughly classified as:

1) be sure to copy a good copy of wa.db to local database (even full re-install did not help)...

2) try not to change wa.db to 777 on the main WA database location, that might flag something, since DB file appears wide open.

this happens when whitelist is initially opened.

3) The selinux i think is known, so not sure what the solution is other than run permissive :(

4) Saw many such random failures, can report them if needed:

So, for the time, I'm Okay :)

Thanks for listening, hopefully this helps someone one day :)
