I am working on creating something to record call in my react native App. For this I have used ReactNative Headless task to get the status of phone and react-native-audio-recorder-player for recording the call but at the end I am getting a file with no sound .

react-native-audio-recorder-player its working fine separetly when I am using this not on call but its saving a file with no sound during call.

Here is my index.js



import { AppRegistry } from 'react-native';
import App from './App';
import { name as appName } from './app.json';
import { AudioRecorder, AudioUtils } from 'react-native-audio'
import AudioRecorderPlayer from 'react-native-audio-recorder-player';
const audioRecorderPlayer = new AudioRecorderPlayer();

// const audioPath = AudioUtils.DocumentDirectoryPath + '/record.aac'
const Rec = async (data) => {
console.log(data.state)
try{
    if (data.state === 'extra_state_offhook') {
      
        const result= await audioRecorderPlayer.startRecorder().then(result=>console.log("started")).catch(err=>console.log(err))
         audioRecorderPlayer.addRecordBackListener((e) => {
            console.log('Recording . . . ', e.current_position);
            return;
           
          });
          console.log(result);
        
    } else if (data.state === 'extra_state_idle') {

        const result = await audioRecorderPlayer.stopRecorder();
        audioRecorderPlayer.removeRecordBackListener()
        console.log(result);
        console.log('Stopped')
    }
}catch(err ){
console.log(err)
}
}
AppRegistry.registerHeadlessTask('Rec', () => Rec)

AppRegistry.registerComponent(appName, () => App);
 

Here is my AndroidManifest.xml

  recIntent.putExtra("action", "phone_state");
  String phoneState = intent.getStringExtra("state");
  if (phoneState.equals(TelephonyManager.EXTRA_STATE_RINGING)) {

        context.startService(recIntent);
        HeadlessJsTaskService.acquireWakeLockNow(context);
    }
}

Here is my RecService.java file

package com.cadric.service;
import android.content.Intent;
import android.os.Bundle;
import com.facebook.react.HeadlessJsTaskService;
import com.facebook.react.bridge.Arguments;
import com.facebook.react.jstasks.HeadlessJsTaskConfig;
import javax.annotation.Nullable;
public class RecService extends HeadlessJsTaskService {
    @Nullable
    protected HeadlessJsTaskConfig getTaskConfig(Intent intent) {
        Bundle extras = intent.getExtras();
        return new HeadlessJsTaskConfig(
          "Rec",
          extras != null ? Arguments.fromBundle(extras) : null,
          5000);
    }
}

Please help me I am stucked , invested more than 20 hours in that already.

Android has strict protection on call recording. see here

Voice call + ordinary app A voice call is active if the audio mode returned by AudioManager.getMode() is MODE_IN_CALL or MODE_IN_COMMUNICATION.

Android shares the input audio according to these rules:

The call always receives audio. The app can capture audio if it is an accessibility service. The app can capture the voice call if it is a privileged (pre-installed) app with permission CAPTURE_AUDIO_OUTPUT.

To capture the voice call's uplink (TX), downlink (RX), or both, the app must specify the audio sources MediaRecorder.AudioSource.VOICE_UPLINK or MediaRecorder.AudioSource.VOICE_DOWNLINK, and/or the device AudioDeviceInfo.TYPE_TELEPHONY.

try using accessibility service. I am also trying using Native Android Kotlin but am yet unseccessful
