There is a guide provided by the App Inventor team on how to create extension components. I hope this answers your question. If not, feel free to ask any additional questions.

yes brother, if you can i need your help.
I want to make extension in which
a webviewer will show an html page from assests and then that html file return something and after a certain time(use of clock timer) returned value by webviewer will stored into a variable.

I would start by copying the source from the WebViewer component that is built into App Inventor. Reading your requirements I am getting that you want communication between the WebViewer and native Android. While googling I found this guide which should get you started. Good luck, let me know if you have any other questions.

Is there a reason that this needs to be an extension?

How do you plan to return something?


what about using the already existing blocks?
