Q:

mobile development tools using HTML5 and C++

I want to find a cross platform mobile development tool that support both Android and iOS. I have some CPU-intensive code in C++, and I want to use HTML5 as my GUI part. I know MoSync can provide a bridge for C++ and HTML5+JavaScript for mobile apps. But besides MoSync, are there any other tools that can integrate code in C++ and HTML+JavaScript. I need to integrate the code of C++/HTML/JavaScript and let code communicate between C++ side and JavaScript side.

A:

Maybe Qt can help you here. Qt is cross platform and there are even ports for Android and iPhone available.
take a look specially at those Qt-moduls:

QtScrip (javascript)
QtWebkit (Html rendering, Html 5 supportet since Qt 5)

Documentation: (abridgement)

Qt (general)
