Hi,

I am unable to update my page indicator .. If once it initialize it does not change.

So how can we reinitialize it.

Thanks
Imran

Hello there :)

I have noticed that in your ExtensibleViewPager.java file, inside the initViewPager() method,
you add onPageChangeListener twice - Once on the argument itself, and once on the mViewPager, which has the same reference.

Just thought worth mentioning this to you. Love your library 👍

You did a very bad copy of this library: compile 'com.romandanylyk:pageindicatorview:+'
Your page indicator have a huge bunch of bugs.

added view pager listener a twice
have merge androidmanifest problem
If we have 3 dots and moving from 3 to 2 - we seeing and animation but returning to the 3.
