ArgbEvaluator error Android 2.2 and Android 2.3.3

Question

I am coding an android application which has multiple activities and files in anims and drawable folder I created. Until today, I was running and testing my app in android 4.2 and it worked well and still works. But today I tried to run it in android 2.2 and 2.3.3. But it failed even if the minSdkVersion is set as 8 (android 2.2)., It throws the exeption below which I could not find any solution for it. Do you have any solution for this error. I really could not find anything about that on net. Thank you.

This is where it throw error :

@SuppressLint("NewApi")
    public void slideUpDown(final View view) {
        final Animation bottomUp = AnimationUtils.loadAnimation(this, R.anim.sowc_bottom_up);
        final Animation bottomDown = AnimationUtils.loadAnimation(this, R.anim.sowc_bottom_down);
        if (!isPanelShown()) {
            hiddenPanel.startAnimation(bottomUp);
            hiddenPanel.setVisibility(View.VISIBLE);
            new Handler().postDelayed(new Runnable() {
                @Override
                public void run() {
                    ObjectAnimator colorFade = ObjectAnimator.ofObject(view, "backgroundColor", new ArgbEvaluator(), Color.argb(0, 0, 0, 0), Color.argb(200, 0, 0, 0));
                    colorFade.setDuration(300);
                    colorFade.start();

                }
            }, 300);
        }
        else {
            ObjectAnimator colorFade = ObjectAnimator.ofObject(view, "backgroundColor", new ArgbEvaluator(), Color.argb(200, 0, 0, 0), Color.argb(0, 0, 0, 0));
            colorFade.setDuration(300);
            colorFade.start();
             new Handler().postDelayed(new Runnable() {
                    @Override
                    public void run() {
                        hiddenPanel.startAnimation(bottomDown);
                         hiddenPanel.setVisibility(View.GONE);
                    }
             }, 200);
        }
    }

ArgbEvaluator was added in API 11 so it does not exist in earlier SDKs.
