Background Calls in Android Not Working

[rohandkn]

Describe the bug
When putting the app in the background (switching to a different app or going to the home screen), the Agora voice call fails after about two minutes. We've noted the following behaviors.

Android 11 Beta: App gets killed after two minutes of background usage
Android 10: App no longer receives microphone input but can hear other members of the call

To Reproduce

1. Install Agora with Flutter
2. Run app and switch to background

Expected behavior

1. I expected the voice call to continue to work in the background.

Desktop (please complete the following information):

i think this is system behavior. if you want the mic to keep working you will need to implement a foreground service.

Same happen to me, App become mute after switched to background android only.

@veyhong as described above, you will need to use foreground service in this case.
i tried finding some example libs here: https://stackoverflow.com/questions/56862952/foreground-service-example-in-flutter
you can implement it by your own if needed.

@plutoless isn't it Need to use Background service instead of foreground since we are put the app in background ?

[Tejareddy94]

i too have that issue. @plutoless it would be great if you provide example for this in your example code.

@veyhong please read here what a foreground service does. https://developer.android.com/guide/components/foreground-services. the idea is it can keep your app working just like working in foreground even when it goes to background.
