ionic v2 error ionic view

Question

I'm developing an ionic v2 app but even working on ionic lab it gets a complete white screen on the ionic view. If I do the same withe the ionic v1 it works.

ionic start sample --v2
cd sample
ionic lab
ionic upload

It shows white but

ionic start sample
cd sample
ionic lab
ionic upload

It works perfectly. No changes on the code at all Thanks

Answer 1

ionic 2 needs at least 4.4 android to work, lost a lot of time on this and there is nothing on the ionic website informing about that. Writing down here to help anyone in the future.

Answer 2

Ionic v2 supports android 4.4 and up. The older browser on pre-4.4 devices do not have the features needed for ionic2 and angular 2 to work. Though this can be fixed with crosswalk.
