Summary

I am developing a recording app with expo-av. I've noticed recently that on Android 12 when a user picks up a call, the app keeps recording but when listening to it later, there is silence while the user was on the phone, but also after he hung up till the end of the recording. On older versions of Android, there is silence while the user was on a call, but it starts capturing audio again when he hangs up. Any idea how to fix it, so it keeps recording after a user hangs up (please note, my intention is not to capture the phone call but keep recording after the user hangs up)?

What platform(s) does this occur on?

Android

Expo Workflow: bare

Minimal reproducible example

Here is a simple repo I prepared:
https://github.com/lniepolski/audio-recording-example

Here are the instructions again:

Run the project on Android 12 by running expo start --android
Start recording
Pick up a call or call someone
Hang up
Keep recording for a bit after hanging up
Listen to the recording- there is no audio captured after hanging up

Also note that I use bare workflow and an older version of the expo in my original project, but the result is basically the same.

@brentvatne the repo I provided in Minimal Reproducible Example is on SDK 47 and the behavior is the same.

I am not 100% sure, but I've changed TARGET_SDK to version 31 (Android 12) and it seems to be working now.

I actually found the solution. It is related to running the service in the background while recording. They key tho, was to add foregroundServiceType to it. So you have to add something like this in your Manifest:

    <service android:name="com.voximplant.foregroundservice.VIForegroundService"
      android:foregroundServiceType="microphone"
      > </service>
