Проблема в строке VoiceControl. java: 253 - audio.setStreamVolume (AudioManager.STREAM_NOTIFICATION, actVolume, 0); : 

public class MainActivity extends AppCompatActivity{

static int REQ_CODE_NO_BEEPS = 1;

requestDoNotDisturbPermission();


private void requestDoNotDisturbPermission() {
    if(audio.getVolumeFixedPolicy()) {
        NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
        assert notificationManager != null;
        if (notificationManager.isNotificationPolicyAccessGranted()) {
            StaticUtils.save(context,"volume_policy",true);
        } else {
            StaticUtils.save(context,"volume_policy",false);
        }
    }else{
        StaticUtils.save(context,"volume_policy",true);
    }
}

if(!StaticUtils.getBool(context,"volume_policy")){
                    volumePolicyText.setVisibility(View.VISIBLE);
                    volumePolicyText.setOnClickListener(new View.OnClickListener() {
                        @Override
                        public void onClick(View view) {
                            // Ask the user to grant access
                            Intent intent = new Intent(android.provider.Settings.ACTION_NOTIFICATION_POLICY_ACCESS_SETTINGS);
                            startActivityForResult(intent, MainActivity.REQ_CODE_NO_BEEPS);
                        }
                    });
                }





@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == MainActivity.REQ_CODE_NO_BEEPS) {
        if(audio.getVolumeFixedPolicy()){
            NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
            assert notificationManager != null;
            if (notificationManager.isNotificationPolicyAccessGranted()) {
                StaticUtils.save(context,"volume_policy",true);
            }
        }
        volumePolicyText.setVisibility(View.GONE);
        Intent i = new Intent(getApplicationContext(),MainActivity.class);
        startActivity(i);
    }
}

}

public VoiceControl(Context context) {
    this.context = context;
    audio = (AudioManager)context.getSystemService(Context.AUDIO_SERVICE);
    assert audio != null;
    actVolume = audio.getStreamVolume(AudioManager.STREAM_MUSIC);
}

public boolean getVolumeFixedPolicy(){
    volumeFixedPolicy = audio.isVolumeFixed();
    return volumeFixedPolicy;
}

public void muteAudio(Boolean muted){
    boolean notificationValid = true;
    if(getVolumeFixedPolicy()){
        if(!StaticUtils.getBool(context,"volume_policy")){
            notificationValid = false;
        }
    }
    if(notificationValid){
        if(muted){
                audio.adjustStreamVolume(AudioManager.STREAM_NOTIFICATION, AudioManager.ADJUST_MUTE, AudioManager.FLAG_VIBRATE);
                audio.adjustStreamVolume(AudioManager.STREAM_MUSIC, AudioManager.ADJUST_MUTE, AudioManager.FLAG_VIBRATE);
        }else{
                audio.setStreamVolume(AudioManager.STREAM_NOTIFICATION, actVolume,  0);
                audio.adjustStreamVolume(AudioManager.STREAM_NOTIFICATION, AudioManager.ADJUST_UNMUTE, 0);
                audio.setStreamVolume(AudioManager.STREAM_MUSIC, actVolume, 0);
                audio.adjustStreamVolume(AudioManager.STREAM_MUSIC, AudioManager.ADJUST_UNMUTE,0);
        }
    }
}

Здесь в функции muteAudio я также использую решение для политики фиксированного объема, где я добавил в манифест <uses-permission android:name="android.permission.ACCESS_NOTIFICATION_POLICY"/>. Когда необходимо программно включить звук, мне нужно установить конкретную громкость c для УВЕДОМЛЕНИЯ. Некоторые устройства выдают эти RuntimeExceptions и SecurityException, что не так?
