How does it works

Until Android 9, Android provides API to capture the Voice calls (MediaRecorder.AudioSource.VOICE_CALL)

From Android 10 & 11, Capturing voice call are restricted, So we will register our app as Accessibility voice provider (MediaRecorder.AudioSource.VOICE_RECOGNITION) and we’ll record the calls.

Caveat

In Android 10, In some devices we will not be able to record the caller’s voice

If Device has active inbuilt call recording feature, In this case the built-in app will have privileged(permission.CAPTURE_AUDIO_HOTWORD) permissions so our will not be able to capture the voice calls.
If the manufacturer had used setPrivacySensitive() is true in audio sources, Then only our voice will be recorded and opponents voice will not be recorded. (Devices like Realme pro 3 pro, Realme 7)

Setup

1. Start Service

var success = function(message) {
    alert("Recording Enabled");
}

var failure = function() {
    alert("Error calling Plugin");
}

cordova.plugins.callrecord.startRecordingService(success, failure);

2. Open Accessibility Service

var success = function() {
    alert("Accessibility Opened");
}

var failure = function() {
    alert("Error calling Plugin");
}

cordova.plugins.callrecord.openAccessibility(success, failure);

3. Open AppSetting

var success = function() {
    alert("AppSetting Opened");
}

var failure = function() {
    alert("Error calling Plugin");
}

cordova.plugins.callrecord.openAppSetting(success, failure);

4. Exclude Power Saver Service

var success = function() {
    alert("Excluded Power Saver");
}

var failure = function() {
    alert("Error calling Plugin");
}

cordova.plugins.callrecord.excludePowerSaver(success, failure);

5. IsExclude Power Saver Service

var success = function(flag) { //boolean flag
    alert("Excluded Power Saver status" + flag);
}

var failure = function() {
    alert("Error calling Plugin");
}

cordova.plugins.callrecord.IsIgnoringBatteryOptimizations(success, failure);

5. Recording File Available Event Listener

Note

Recording service will be running independent of the application, This event is in application layer hence event will not be triggered if

App was not launched since the mobile booted

App was killed forcefully

  document.addEventListener('fileAvailable', function() {
      //File Operations
  });
