NPE in InkPageIndicator

I have not changed anything notable in the indicator, but essentially, there is a situation where dotCenterX is null. It's a bit hard to pinpoint the reason as most of the variables are initialized at different times.

A possible solution is to simply initialize everything, even if it means being an empty array. Maybe you'll have a better idea of what the actual cause is though.

I'm also having this issue,..., and after a bit of debugging, it appears that in the failing case,
onDraw is being called before onMeasure. onMeasure is where it sets up dotCenterX.

I find that this bug occurs when there is a chance in pager size. For example, the ViewPager was initially size 1, then it becomes size 5, and it fails to re-measure itself. This is very hard to reproduce. It doesn't happen all the time.

I couldn't access the Crashlytics log. Assigning to Nick for further triage.
