No it didn't work ,the webview was still floating on top of other layed out widgets.Other QML elements fit in ok ,it is just the webview that could not. A temporary solution we used is this :
https://github.com/gakwaya/qt-android-native-web-view-example ,I hear that when your UI is completely done in QML ,you don t have this problem ( the mini browser example is a demonstration of that.We were planning on redesigning our UI in QML anyway so this is a plus.
