Run V3 App without Crosswalk?

Greetings,
Its possible build one app with succesfull webview for Ionic v3 withouth use Crosswalk Webview or Crosswalk Lite ??

Crosswalk is sunsetted. So don’t use it. The only reason to use it is if you are targeting old phones.

Old phones since what api level ??
On KitKat 4.4.4 show blank screen,

Here i read that support ir for 4.4.4 but i build and test on 4.4 and .5.1.1 en show Blank screen

That’s only 10.5% of users. Which means the support is limited and being reduced over time. But Crosswalk is probably needed for Android 4.x.
