Keep audio on background

[gwendall]

Right now, switching to another app or locking the phone shuts the sound down. Is there a way to keep it running ?

[LichKing-2234]

you may need to add foreground service to the android code.
https://docs.agora.io/en/faq/android_background

@LichKing-2234 Any chance you have more info on how to integrate this? Shouldn't this be included in this SDK?

[LichKing-2234]

Although we will not integrate Callkit (iOS) and ConnectionService (Android) in the SDK in the near future, if you just want the app to keep calling in the background, you can call setParameters('{"che.audio.opensl":true}'); on the Android platform(>2.3.2), enable Background Modes and select the Audio, Airplay, and Picture in Picture, and Voice over IP options on the IOS platform.

@LichKing-2234 Where should I add the code setParameters('{"che.audio.opensl":true}');? Could you please tell me how to add Android code on React Native project?

[LichKing-2234]

@tak-bro RN SDK also export setParameters function

[tak-bro]

@tak-bro RN SDK also export setParameters function

Thanks!

Hi fellows,
I can't find setParameters in the react-native SDK nor in the react-native-agora package.
WDYMN when u say RN SDK also export setParameters function?

UPDATE: Found it.
For anyone looking in the future, the setParameters method sits on the RtcEngine instance.

@eyalcohen4 here.

[arya-man]

@LichKing-2234 what do you mean by export the function? Is await this.agora.setParameters('{"che.audio.opensl":true}'); not enough? If so, what extra thing are we supposed to do?

[LichKing-2234]

@eyalcohen4 any problem?

[dhavalagile]

audio not working when app goes in backgroud after 1 min.

I had set await _engine.setParameters('{"che.audio.opensl":true}');

[LichKing-2234]

@dhavalagile you should start a foreground service
https://docs.agora.io/en/Interactive%20Broadcast/faq/android_background

[arya-man]

Any success on starting a foreground service? I have no android coding experience, so for me its super confusing

[hongzhou85]

How about for iOS? any web document or information on this? I want to keep audio on as well when app goes into background.

[LichKing-2234]

[hongzhou85]

Does this need to add background processing and fetch to the info,plist for iOS on xcode?

[hongzhou85]

I have successfully enabled this on iOS by enabling the VoIP and Audio modes. How do we do it on React native Android?

[LichKing-2234]

@hongzhou85 I have commented above.

[jaymovaliya]

@hongzhou85 , can you share some code SS for doing this?

[hongzhou85]

@jaymovaliya this one for ios would work

[hongzhou85]

For Android, I'm going to attempt this for foreground service.
https://github.com/Raja0sama/rn-foreground-service

Another paid alternative may be this:
https://notifee.app/react-native/docs/android/foreground-service

Otherwise, for React Native you would have to code the headless js, which has little example on how to do it.

How did you do this?
I checked those options in background mode in XCode but the app still closes after 5 second going to background

[OscarJuniusDev]

My app also closes after exactly 5 seconds in background, although the user is in an active call. Have you found a solution for this?

Hi,
Sorry for delay, yes I found the solution,
In IOS, you have to check things comes above in XCODE then put all the functions related to redux and storage in this:

if (AppState.currentState === 'active') {
      //do whatever you want
}

In ANDROID, you have to run a foreground service which is listed below,

ANDROID FOREGROUND SERVICE:

I use this package for foreground service: @supersami/rn-foreground-service

import ReactNativeForegroundService from '@supersami/rn-foreground-service';

export const initForegroundService = () => {
  return new Promise((result) => {
    ReactNativeForegroundService?.add_task(() => {}, {
      delay: 100,
      onLoop: true,
      taskId: 'taskid',
      onError: (e: any) => {},
    });
    result(true);
  });
};
export const removeForegroundService = () => {
  ReactNativeForegroundService?.remove_task('taskid');
};

export const startForegroundService = () => {
  ReactNativeForegroundService?.start({
    id: 144,
    title: '...',
    message: '...',
  });
};
export const stopForegroundService = () => {
  if (ReactNativeForegroundService) {
    ReactNativeForegroundService?.stop();
  }
};

Follwing this #176 (comment) approach has rejected my ios app from app store saying that -

Your app declares support for VoIP in the UIBackgroundModes key in your Info.plist, but it does not include any Voice over IP services.

Next Steps

To resolve this issue, please revise your app to either add VoIP features or remove the "voip" setting from the UIBackgroundModes key.

We recognize that VoIP can provide "keep alive" functionality that is useful for many app features. However, using VoIP in this manner is not the intended purpose of VoIP.

I believe this reply means you have not utilized any VoIP features in your App, so including it is not required. Appstore do not accept additional permission request without having actual features using the permission.

Hey @SamarthKejriwal did you get this sorted? My app just got rejected from Apple for the exact same reason. Why is this being suggested as an approach? Is there another solution to keep audio in background?

[cranberry08]

I got the same thing… any advice

[nyoung697]

@cranberry08 I removed the VOIP background mode and just left in the Audio, Air Play, Picture in Picture.

https://docs.agora.io/en/Voice/ios_audio?platform=iOS#additional-settings-and-permissions

Those docs there led me to try that out.

Apple accepted our app and it seems to work fine when in the background.

Apple review did ask me to make a video demonstrating why I needed background audio capabilities.

[cranberry08]

Hello Nick, Thank you!! That was very helpful. Good luck to you.

[abhijith-sys]

is there any updates form agora sdk for enabling the voice call even if the app is in the background?.what is the best solution for this problem

[jfbourne]

Same issue here, any built-in solution from Agora to achieve this on Android without having to write a java service to do this?
