Unsolved Is it possible to build/run the "Extending QML" chapter 6 project on iOS and/or Android?

[VRHans]

It works perfectly fine on OSX, Linux, and Windows 10 - on iOS I get a runtime error:

'qrc:///app.qml:41:1: module "Charts" is not installed'

On Android I get a build error:

'No application .pro file found, not building an APK.'

The clocks sample works just fine across all platforms.

Has anyone on this forum built a working 5.5 (or other) QQmlExtensionPlugin for Android and/or iOS?

Thanks!
