What is Crosswalk and why we need it?


When we develop with PhoneGap/Cordova, we use the standard WebView that the system provides for us. The situation is not bad with iOS. WebView in iOS from version to version works almost the same. There are only small changes and improvements provided for now.

However, with Android, the situation is totally different. In the different variations of the platform, different versions of WebView are used. There are differences in:

  • JavaScript API

  • CSS properties support and syntax

  • Specific interface that renders flow

Many other differences and odds can also be found.
