Module fails to install on Android 16 (different appid, because Google.)

[JCionx]

I'm running the latest Android 16 beta version and when attempting to install the module on Magisk, I get this log:

Weird! Could you send me the output of lsof | grep libbluetooth with Bluetooth turned on? Run this as root.

[JCionx]

Ran the command after running su in ADB. I'm not sure if that's how I run as root.

This is the output:

binder:1020_2  1020 audioserve  mem       REG               0,53    101896       2792 /vendor/lib64/libbluetooth_audio_session.so

[kavishdevar]

ah, i see. it's under com.android.bt instead of com.android.btservies... gonna fix it soon and share it with you for testing.

that's the correct way to run as root :)

[kavishdevar]

meanwhile, could you try running

mkdir -p /tmp/overlayfs-test/{lower,upper,work,mount}; mount -t overlay overlay -o lowerdir=/tmp/overlayfs-test/lower,upperdir=/tmp/overlayfs-test/upper,workdir=/tmp/overlayfs-test/work /tmp/overlayfs-test/mount

in case you're wondering: this tests for overlayfs (this is important to patch libs located under /apex.

lmk if it throws an error or doesn't print anything and just exits.

[JCionx]

Just ran it under root and got no output. If I run echo $? to print the return code of the last ran thing, I get 0, which usually means success.

[kavishdevar]

yup! overlayfs's supported - great! here's something you can test

btl2capfix.zip

[JCionx]

I think I got the same log:

Btw, I installed the Magical Overlayfs module with the read/write mode, but had the same log when I didn't have it installed.

[kavishdevar]

ugh, shared the wrong zip - sorry! the updated one should be there in the nightly release shortly!

[JCionx]

Just tried that out and got a different error

[kavishdevar]

huh, disabled that overlayfs check for now. here:

btl2capfix.zip

[JCionx]

It installed successfully, but the AirPods keep disconnecting. The app shows the AirPods sometimes, with 0% battery and none of the controls work.l:

This is the installation log if you need it:

- Copying zip to temp directory
- Installing btl2capfix (3).zip

[kavishdevar]

which phone are you using?

[JCionx]

It's a Pixel 7a

[kavishdevar]

ah, pixel... don't know why, but every (except one or two) pixel user reports the same problem. I could try and build the library from source (when I have time), but I still can't not guarantee it'll work for you.
