Even registering broadcast receiver in Manifest file,you need to register in dynamically in Oreo+ otherwise it will not work. Try this.Add this code in main activity or in startCommand in Service.It worked for me.I have tested this code on Android 10 too..worked perfectly.You need not to register broadcast receiver in Manifest file.

@Override
    protected void onStart() {
        super.onStart();
        IntentFilter intentFilter=new IntentFilter(Constants.BROADCAST_DETECTED_ACTIVITY);
    intentFilter.addCategory(Intent.CATEGORY_DEFAULT);
        registerReceiver(broadcastReceiver,intentFilter);

    }
