How to read Animation scale duration flag in Marshmallow

I am facing problem while reading Animation scale duration flag in Marshmallow. Same code is working in earlier version of Marshmallow (6.0.0).

I am using android.app.Fragment.setCustomTransition() method for fragment animation. When Animation scale duration is 0 in developer option settings, fragments do not get displayed. So i had to disable animation over this condition.

My code snippet:

public static boolean isAnimationOff()
    {
        final float animatorSpeed;
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1)
        {
            animatorSpeed = Settings.Global.getFloat(
                    context.getContentResolver(),
                    Settings.Global.ANIMATOR_DURATION_SCALE,
                    0);
        }
        else
        {
            animatorSpeed = Settings.System.getFloat(
                    context.getContentResolver(),
                    Settings.System.ANIMATOR_DURATION_SCALE,
                    0);
        }
        return animatorSpeed == 0;
    }

The problem is :this code is returning true on each invoke even if animation scale duration is not 0.

Has anyone faced this issue?

Edit1

Following is the code snippet where I use isAnimationOff() method to load a fragment:

private void loadFragment(Fragment fragment)
{
    FragmentTransaction transaction = getFragmentManager().beginTransaction();
    if (!Constants.isAnimationOff())
        transaction.setCustomAnimations(animSlideIn, animSlideOut);
    transaction.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_FADE).replace(R.id.frameTopContainer, fragment)
            .commitAllowingStateLoss();
}

Here is the custom LinearLayout that has custom property:

public class FractionLinearLayout extends LinearLayout
{

    DisplayMetrics matrics = getContext().getResources().getDisplayMetrics();

    public FractionLinearLayout(Context context, AttributeSet attrs,
                                int defStyleAttr)
    {
        super(context, attrs, defStyleAttr);
        // TODO Auto-generated constructor stub
    }

    public FractionLinearLayout(Context context)
    {
        super(context);
        // TODO Auto-generated constructor stub

    }

    public FractionLinearLayout(Context context, AttributeSet attrs)
    {
        super(context, attrs);
        // TODO Auto-generated constructor stub
    }

    public float getFractionTranslationX()
    {

        return getWidth() > 0 ? super.getTranslationX() / getWidth() : Float.MAX_VALUE;
    }

    public void setFractionTranslationX(float translationX)
    {

        int width = getWidth();
        super.setTranslationX(width > 0 ? width * translationX : Float.MAX_VALUE);
    }

    public float getFractionTranslationY()
    {

        return getHeight() > 0 ? super.getTranslationX() / getHeight() : Float.MAX_VALUE;
    }

    public void setFractionTranslationY(float translationY)
    {
        int height = getHeight();
        super.setTranslationY(height > 0 ? height * translationY : Float.MAX_VALUE);
    }

    public float getAnimWidth()
    {

        return getLayoutParams().width;
    }

    public void setAnimWidth(int animWidth)
    {

        getLayoutParams().width = animWidth;
        requestLayout();
    }
}

I had an issue in my FractionLinearLayout class. In set setFractionTranslationX() method, getWidth() was returning 0 at the very first call. That led my code to prevent Fragment to appear when animation is off. Now i have replaced getWidth() line with getResources().getDisplayMetrics().widthPixels and everything is working fine.

Updated Code:

public class FractionLinearLayout extends LinearLayout
{

    DisplayMetrics matrics = getContext().getResources().getDisplayMetrics();

    public FractionLinearLayout(Context context, AttributeSet attrs,
                                int defStyleAttr)
    {
        super(context, attrs, defStyleAttr);
        // TODO Auto-generated constructor stub
    }

    public FractionLinearLayout(Context context)
    {
        super(context);
        // TODO Auto-generated constructor stub

    }

    public FractionLinearLayout(Context context, AttributeSet attrs)
    {
        super(context, attrs);
        // TODO Auto-generated constructor stub
    }

    public float getFractionTranslationX()
    {

        return getWidth() > 0 ? super.getTranslationX() / getWidth() : 0;
    }

    public void setFractionTranslationX(float translationX)
    {
        int width = getResources().getDisplayMetrics().widthPixels;
        super.setTranslationX(width > 0 ? width * translationX : 0);
    }

    public float getFractionTranslationY()
    {

        return getHeight() > 0 ? super.getTranslationY() / getHeight() : 0;
    }

    public void setFractionTranslationY(float translationY)
    {
        int height = getResources().getDisplayMetrics().heightPixels;
        super.setTranslationY(height > 0 ? height * translationY : 0);
    }

    public float getAnimWidth()
    {

        return getLayoutParams().width;
    }

    public void setAnimWidth(int animWidth)
    {

        getLayoutParams().width = animWidth;
        requestLayout();
    }
}

But Still I don't knowl, why is ANIMATOR_DURATION_SCALE flag not working in Marshmallow.
