AudioManager Disable Headset Through Reflection No Longer Working

I used the AudioManager Method: setWiredDeviceConnectionState to disable the headset on my device. It worked fine until I came across some newer models and now it does not work. I assume this is because the Hack does not work anymore. Is there any upgrade to the previous hack or any other ways to disable the headset from the device? I need to be able to play a tone via the In-Call_Speaker while a headset is plugged it. Please Help!!!

This is the exception it gives when ran:

W/System: ClassLoader referenced unknown path: /data/app/com.example.raptorroboticstest-2/lib/arm64
W/System.err: java.lang.NoSuchMethodException: setWiredDeviceConnectionState [int, int, class java.lang.String]

This is the method to disable/enable the headset:

    AudioManager manager = (AudioManager) getApplicationContext().getSystemService(Context.AUDIO_SERVICE);
    try {
        Class<?> cl = Class.forName("android.media.AudioManager");
        setWiredDeviceConnectionState = cl.getMethod("setWiredDeviceConnectionState", new Class[]{Integer.TYPE, Integer.TYPE, String.class});
        //4 is for the headset with microphone 8 is for headset without microphone
        //0 is for off and 1 is for on
        setWiredDeviceConnectionState.invoke(manager, new Object[]{4, 0, "device"});
        setWiredDeviceConnectionState.invoke(manager, new Object[]{8, 0, "device"});
    } catch (ClassNotFoundException e) {
        e.printStackTrace();
    } catch (NoSuchMethodException e) {
        e.printStackTrace();
    } catch (InvocationTargetException e) {
        e.printStackTrace();
    } catch (IllegalAccessException e) {
        e.printStackTrace();
    }
