    CirclePageIndicatorClass = CirclePageIndicatorInner;
}

But i cannot use it with any Android SDK > API23:

ensureCirclePageIndicatorClass();
var dots = new CirclePageIndicatorClass(application.android.currentContext);
var layoutParams = new android.widget.RelativeLayout.LayoutParams(android.widget.RelativeLayout.LayoutParams.MATCH_PARENT, android.widget.RelativeLayout.LayoutParams.WRAP_CONTENT);
layoutParams.addRule(android.widget.RelativeLayout.ALIGN_PARENT_BOTTOM);
dots.SetViewPager(this._viewPager, this.position);
dots.mSnapPage = this.position;
this._android.addView(dots, layoutParams);

Then i get this exception:
