Call recorder not working in android 10 (Q)

Question

Call recorder is recording blank for the duration in Android 10 (Pixel 3A). It was working fine for all phones till Android 8 and in Android 9 most phones were recording onl

Answer 1

As per Google's new permission policy no other third party apps (Except system apps) can record calls from Android 9 Pie.

This change will not affect previous recordings or call recording in general.

Answer 2

I am using Realme2pro device having version android 10 it is working for me by using Accessibility try this code

To implement Accessibility go through this link

public class Accessibility extends AccessibilityService {

Service mService = null;

@Override
public void onAccessibilityEvent(AccessibilityEvent event) {
    Log.d("MyAccessibilityService", "Shrinidhi: onAccessibilityEvent");
}

@Override
public void onInterrupt() {

}


@Override
protected void onServiceConnected() {
    Log.d("MyAccessibilityService", "Shrinidhi: onServiceConnected");
}

@Override
public void onCreate() {
    this.mService = this;
    Log.d("MyAccessibilityService", "Shrinidhi: onCreate");
 }
}

and add AudioSource to recorder.setAudioSource(MediaRecorder.AudioSource.VOICE_RECOGNITION);

 recorder = new MediaRecorder();
    recorder.setAudioSource(MediaRecorder.AudioSource.VOICE_RECOGNITION);
    recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
    recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
    recorder.setOutputFile(file.getAbsolutePath());

Hope it work :)

Answer 3

It's possible using Accessibility Service.

Remote call recorder and BoldBeast both record perfectly both side voice in Android 10 (Pixel 3A) without having to root or being a system app. Both of them use Accessibility service.
