I also get this error on some android 4.4 devices. It happens after I call this line second time 

    circleIndicator.setViewPager(viewPager);

Without calling I cannot update the position of circle indicator, I tried circleIndicator.invalidate() etc. no help.

temporary i comment //if (animator.isRunning()) animator.end(); //animator.setTarget(Indicator); //animator.start(); fix this hope will fix soon

LiuDeng commented 8 years ago
