on a quick log in the adb logcat i can see those errors who stand out

[chenxiaolong]

Hmm, I have no idea what would be causing that, especially the I/O error.

Do you happen to have Magisk's denylist enabled for any system apps?

[carstengrimm]

I have adjusted the issue, as it makes not that much sense to have issues on the debug versions.
i have now installed the 1.34 build, and there's no bcr application found in the launcher.

inside

data/adb/modules/com.chiller3.bcr/system/priv-app/com.chiller3.bcr/

i can see there's an app-release.apk

(let me also check denylist)

[carstengrimm]

i'm using delta magisk, which features magisk hide/SuList
as with 1.34, the app is not recognized in launcher, i can not select is as SuList exception (make it access SU)

[chenxiaolong]

Can you post the output of:

ls -lR /data/adb/modules/com.chiller3.bcr /system/priv-app/com.chiller3.bcr /system/etc/permissions/privapp-permissions-com.chiller3.bcr.xml

I took a quick look at Magisk Delta and it seems that its mount logic is very different from the normal Magisk.

Also, does BCR work if you turn off SuList completely? I wonder if BCR's apk is getting hidden from Android itself.

[carstengrimm]

i have manually installed the APK from Zip, as well as make add it to SUList,
give permissions and undo freeze-functions.

seems like it doesn't trigger root

tried from scratch, can't find bcr app after magisk install.

[chenxiaolong]

That's expected. BCR only uses Magisk for installation. Once installed, it never uses root (it only needs system app permissions).

Based on this, I'm not sure what else would cause the issue. Even if all of the other files were missing, the app should still at least show up.

[carstengrimm]

It may be the case that the app listed there is the one I have manually installed extracting from the zip file ... Or that cannot be the case? E.g. seeing the path.

And with the manual installation maybe not having sufficient rights to record,... After setting all options within the app and making sure battery saver isn't on, I made a few test calls. No recordings have been saved and there was no notification either.

I undid everything before and after flashing 1.34 the application cannot be found in the launcher.

That can't be the case. Manually installed apps end up in /data/app/.

And with the manual installation maybe not having sufficient rights to record,...

Yep, this is the main reason that Magisk is needed for installation. Android only allows system apps to access the call audio.

I don't really have any ideas for what else to try, but if you're willing to upload the full logcat with BCR installed, I can take a look and see if I find anything unusual.

[carstengrimm]

what exactly will you need?

[chenxiaolong]

In the logcat, I'd mainly be looking for anything related to com.chiller3.bcr, magisk, the Android package manager (installd), and selinux (avc: denied).
