Salman_Dev · July 10, 2021, 11:34am

why, there is a list view and camera components?

raj_kumar · July 10, 2021, 11:38am

you suggest me for this block thats why

Salman_Dev · July 10, 2021, 11:38am

Okay let me explain

Salman_Dev · July 10, 2021, 11:43am

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 .
