      // following code does... except it doesn't on Android 5.0. Instead, the result is that the
      // right side color is 50% opacity of leftColor. The following code works on Android 5.0,
      // but assumes a Drawable hierarchy that may not be true if the device manufacturer deviates
      // from the AOSP design. If that is the case, then the right hand side will not change.
      StateListDrawable drawable = (StateListDrawable) seekbar.getProgressDrawable();
      if (drawable.getCurrent() instanceof LayerDrawable) {
        LayerDrawable layerDrawable = (LayerDrawable) drawable.getCurrent();
