Maybe you can improve your chance of getting solutions by learning how to correctly search your query in the community.
For example:

there is no CustomWebView option Found . how can i use

First you have download the extension here :

CustomWebView : An extended form of Web Viewer

Second, learn how to add extensions in MIT AI2 :

So, your app currently only uses the WebViewer Component right?

So if you using CustomWebView by vknow360 that means you don't need to use WebViewer Component which mean you only need an arrangement to make it as WebView.

You may want to learn how to code with App Inventor. Knowing how to use Blocks is more useful than to randomly copying code Blocks that you do not understand.

Here are some resources to help you learn to use the AI2 tools. A very good way to learn App Inventor is to read the free Inventor's Manual here in the AI2 free online eBook http://www.appinventor.org/book2 ... the links are at the bottom of the Web page. The book 'teaches' users how to program with AI2 blocks.

There is a free programming course here http://www.appinventor.org/content/CourseInABox/Intro and the aia files for the projects in the book are here: http://www.appinventor.org/bookFiles

How to do a lot of basic things with App Inventor are described here: http://www.appinventor.org/content/howDoYou/eventHandling .

Also look here http://kio4.com/appinventor/index.htm and here http://www.imagnity.com/tutorial-index/ for more tutorials.

Learn about components http://ai2.appinventor.mit.edu/reference/components/
and visit the Library http://appinventor.mit.edu/explore/library Help>Library on the MENU

is there any possibility that the scanner will work?
