React-native-swiper: onScrollBeginDrag not fired on Android

[zakster12]

This method is fired on iOS but not fired on Android. And I needed instead onMomentumScrollEnd because I would like to catch if the user is on the last index and try to swipe again I can show my Login screen. Any ideas why it's not fired on Android and whether there is a workaround?

I also tried to set react-native-swiper inside ScrollView as my idea was to catch when the user tries to swipe (event comming from the ScrollView) and knowing that I am on last slide using the onMomentumScrollEnd I know when to continue to Login. But the problem was that the ScrollView was taking all the events and swiper even didn't work. After a bit of research I found that on Android we should use NestedScrollView instead ScrollView (https://github.com/mohtada-h/react-native-nested-scrollview) but the problem was the same.

Anyone else having this problem?

Some questions:

• RN version ? RN Swiper version ?
• Can your fork the project and create (or change) an example in which you reproduce your bug ?

It would help us a lot.
Thanks

I'm also seeing this. onScrollBeginDrag doesn't fire on android but it does on ios. RN 0.45.1, Swiper 1.5.12.
