Shizuku support [question] [enhancement]

[LCernei]

Hi,
I was wondering:
Can this app use Shizuku instead of root / Magisk? (or even alongside Magisk?)
I understand that it requires additional development, but is it even possible?
Are there some permissions that BCR needs that are not available with Shizuku?
This can provide an easier installation and potentially a wider userbase.

Unfortunately, this is not possible. All call recording apps require the CAPTURE_AUDIO_OUTPUT permission and BCR additionally requires CONTROL_INCALL_EXPERIENCE to detect when calls begin/end. Neither of these system app permissions are available to adb/Shizuku (full list of permissions they support: https://github.com/aosp-mirror/platform_frameworks_base/blob/master/packages/Shell/AndroidManifest.xml).

Hi,
Sorry to reopen the issue but I see that both permissions are now available in shizuku

Nice! I hadn't seen that.

I looked into it today and unfortunately, while the permissions might be sufficient now, Shizuku does not support exporting services. There's no way to export BCR's InCallService in a way that Android will detect it and notify BCR of phone calls. Replacing that with Android's legacy call detection API might work, although that has limitations like not being able to properly handle call waiting, holding, conference calls, etc.

Accessing files, contacts, call information, etc. also needs to be split out from the recording logic because all of that requires access to a valid Context, which is not available from a Shizuku user service.

So with that said, I think it's theoretically possible for someone to write a limited call recorder for Android 14+ that uses Shizuku and does not require root. I won't be implementing this in BCR though. It would require a pretty significant rewrite and I don't really have any interest in doing it.

Thank you for the clarification
