The cordova-plugin-crosswalk-webview is based on Chromium webview engine for Cordova. It is faster than regular android webview.
Unfortunately, the Crosswalk project has been already retired.
However, you can still use the cordova-plugin-crosswalk-webview plugin.
In order to use the cordova-plugin-crosswalk-webview with the cordova-googlemaps-plugin v2.0, you need to install the plugin, then add the below two preferences in the config.xml.
cordova plugin add cordova-plugin-crosswalk-webview
<preference name="xwalkZOrderOnTop" value="true" />
<preference name="BackgroundColor" value="0" />
For Android, just type this command:
$> cordova run android
That's it!
