Ionic 2 - Crosswalk is a prerequisite?

I have different problems depending on the version of Android (4.4, 5.0 …):

  • scroll not working on 4.4, but working 5.0
  • Behavior of a button, the icon should change. The behavior is not the same with Android 4.4 and 5.0
  • and more…

Is crosswalk a pre-equisite for using Ionic 2?

Crosswalk is technically an important optimization to have for an app running on Android 4.4 or lower, not a pre-requisite. That said in many cases replacing the WebView from an old system with crosswalk solves many problems.

Thanks for your answer.
