Ionic and WebGL

Hello.

My client wants to embed 360° panorama preview from https://pannellum.org/ in Ionic app.
I prepared simple testing application with pannellum and it works only on browser and iOS. On Android (4 and 5) it alerts: “Your browser does not have the necessary WebGL support to display this panorama.”. Is it true? It’s really impossible to run WebGL in Ionic on Android?

I tried cordova-plugin-crosswalk-webview, after installing it I had errors:
