Bug description

1. Basic Call Recorder fails to create /storage/emulated/0/Android/data/com.chiller3.bcr and it crashes when trying to save a call recording.
2. Symfonium fails to download album art from Subsonic server because it fails to create /storage/emulated/0/Android/data/app.symfonik.music.player/cache

Steps to reproduce

For BCR

1. Install a KSU metamodule and reboot.
2. Download BCR and flash the zip as a KSU module from KernelSU Manager.
3. Reboot, open BCR, and grant it all necessary permissions.

5. Receive a call, BCR will try to record it but will crash.

For Symfonium

1. Install Symfonium from the Play Store.
2. Open the app and configure it by adding a Subsonic server.
3. Symfonium will fail to download album art from the server because it fails to create the cache folder.

Thought with this commit the issue would be gone as it did for most of the known issues I came along on cepheus, lmi and alioth.
But apparantly it doesn't fix all not even after clean flash.

Can see some specific denial in logs

temp bypass solution is to chmod 777 -R /storage/emulated/0/Android/data
my users reported no issue on clean flash
also I personally can't reproduce on none of my devices

later edit:
maybe just write a init script to do the chmod part, but kinda hacky way

Could this be because during the initial setup process I restored my apps and settings from Google Backup?

[raystef66]

Yeah thought on doing so when I had the Sygic issues (before 21.02 builds) but then I guess we should do so for all apps.
Smt like this :

on post-fs-data
    mkdir /data/media/0/Android/data/com.sygic.aura 0771 media_rw media_rw
    mkdir /data/media/0/Android/data/com.sygic.aura/files 0771 media_rw media_rw
    restorecon /data/media/0/Android/data/com.sygic.aura

Or smt like this on adb :

adb shell "mkdir /storage/emulated/0/Android/data/com.sygic.aura"
adb shell "mkdir /storage/emulated/0/Android/data/com.sygic.aura/files"

I really have no idea

chmod 777 -R /storage/emulated/0/Android/data
-R should make all dirs if am not mistaken
on create call, should just take over from parent dir I think

[raystef66]

Wouldn't 777 on data be kinda drastic in a way to open up all kinds of possible vulnerability (malware etc...) bcs now you give all apps these rights, even among themselves.
@zenwav Did you try to rm the Symfonium app and redo?

775 as test then

Yes, I did try that.

As a temp solution this module (credits to @omersusin) (remember this sets all to 777)
