Non-persistent permissions on TCL TV.

[NCHagelstein]

Hi,

I am trying to use this app with my TCL TV. Apparently everytime I reboot the device the permissions for reading notifications get revoked. Following the instructions in the repository I was able to get things up and running.

TV is running Android 11. I built the app myself on Windows in release mode.

Thank you for the report. However there is nothing I can do about the TV.

I added a fix to reconnect to the service on reboot. However, it won't re-acquire the permission if it was actually revoked by the TV: acquiring the permission must always be done manually.
Please try version 1.1.5 and tell me if you see any improvement.

I encountered similar symptoms on a TCL Google TV: the MQTT connection test succeeded and notification-listener access appeared enabled, but playback events stopped unless I manually opened MediaSession2MQTT.

ADB logcat showed TCL firmware blocking the listener service:

TclAppBoot: forbid bind service

with:

reason = callee_does't_have_OP_AUTO_START_permission

Granting TCL’s hidden auto-start app-op fixed Netflix events for me:

adb shell appops set be.digitalia.mediasession2mqtt APP_AUTO_START allow

You can verify it with:

adb shell appops get be.digitalia.mediasession2mqtt

Some TCL firmware may call the operation AUTO_START instead. TCL’s Safety Guard app may also expose it under Permission Shield → Auto Launch Permission.

This fixed the background listener being blocked by TCL firmware and notifications were working after a reboot.

@kmcc049 Thank you for your investigation. I will add extra information about this TCL Safety Guard feature in the README.

Thank you so much for digging deeper on this guys. The fix by @kmcc049 fixed the issue.
