Abstract— In the Internet era, mobile devices have become more and more popular because of their portability. Web-based operating system (OS) is a mobile operating system based on web technologies and has great potential for growth. However, mobile applications are mainly developed for Android and iOS, and cannot run in a Web-based OS due to the incompatibility between different platforms. Aiming to expand the application ecosystem of the Web-based OS and based on the fact that many mature applications’ low-level code is written in C/C++, we propose B2GPAPI, a framework that provides a runtime for C/C++ applications in the Web-based OS. B2GPAPI makes it possible that existing mature mobile applications can directly run in a Web-based OS. To implement the framework, on the one hand, we employ thehtml tag in web applications as a connection with the dynamic link library of the C/C++ application; on the other hand, in Web engine of the Web-based OS, we provide an event interface to deliver the event information from web application to the C/C++ application and a graphic rendering interface to display the interface of the C/C++ applications. In order to verify the efficiency of the framework, we compare B2GPAPI’s graphics rendering interface with the WebGL interface. Experimental results show that B2GPAPI has good practicability and outperforms than WebGL.
