Microphone does not work when switching to other applications during a call

[MageDelfador]

In Android 14, there is no permission to record audio in the background, and meshenger switching to the background can't record. But the camera can work fine in the background.

[mwarning]

Interesting, I do not know how to fix this.

Samsung?

Please try to add this to manifest:

android:foregroundServiceType="camera|microphone"

[mwarning]

@iddq that might work. I have added it without being able to test it for now.

So I have two Android 13 devices, Samsung and Xiaomi. I also experience the above problem, but only on Samsung.

I tested the latest code and it crashed.

My device is Xiaomi.

[mwarning]

I am able to reproduce the error now.

[iddq]

tested on samsung android 13 and it is working now. the microphone access is still working while meshenger is not in foreground.

[mwarning]

i can reproduce the crash for Android 14. I think the foreground service type is not accurate. The service is not meant to record audio or to use the camera. That would be the job of the CallAcivity.

[iddq]

Does this error occur during a video call? I only use it with audio. How to reproduce the issue?

Crash on startup, only on Android 14.

The error message clearly states that in addition to the FOREGROUND_SERVICE_MICROPHONE permission, other permissions such as RECORD_AUDIO are also required. At runtime, you need to check for the presence of the RECORD_AUDIO permission and request it from the user if necessary.

[mwarning]

hm, I do not have much time atm. to debug this and provide a solution. Let's hope we can get this fixed in the next release.
