It is not feasible to utilize native Android/iOS languages for this task.
The primary purpose of these languages is to operate on mobile devices, not within a web environment. Consequently, directly inserting the source code of a mobile application into a web page is not supported.
Nevertheless, you do have the option to develop a web-based version of your app (depending on its complexity). One approach is to create a web adaptation of the mobile application using HTML, JavaScript, and CSS. Additionally, you could opt to build a Flash application, although this method may be considered somewhat outdated.
In light of the advancements in HTML5, CSS3, and JavaScript, web applications are becoming increasingly prevalent. I suggest referencing this book for guidance on constructing web apps: http://www.example.com/Building-Web-Apps-JavaScript-CSS3
