Android Mobile Vision access to camera parameters

Question

Is it posible access to Camera parameters in CameraSource on Android's Mobile Vision API 8.4? I want to be able to adjust some Camera parameters (Shutter speed, ISO, aperture,...).

UPDATE I try to do it using this code:

public Camera getCamera(CameraSource cameraSource) {

    Field[] declaredFields = CameraSource.class.getDeclaredFields();
    for (Field field : declaredFields) {
        if (field.getType() == Camera.class) {
            field.setAccessible(true);
            try {
                Camera camera = (Camera) field.get(cameraSource);
                if (camera != null) {
                    return camera;
                }

                return null;
            } catch (IllegalAccessException e) {
                e.printStackTrace();
            }

            break;
        }
    }

    return null;
}

But it doesn´t work for me, field.get(cameraSource); return null when get the field with type Camera.class.

Android-Vision team, do you plan to add these feature in the next releases?

Best regards,

We have no plans to expose the underlying camera in the official API. But there's an open source version of this class that you can use and modify:
