Hello I am new to the app creation. I am interested in creating a means of answering a call end ending through real switches, preferably throug the USB.
A unique wide interface would probably works as well. Can you help? Thanks!
What you might try using Android Studio
What you might be able to do using App Inventor
is discussed in the PhoneCall component documentation. Essentially you probably cannot do what you want to do using App Inventor.
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 App Inventor 2 Book: Create Your Own Android Apps ... 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 Course In A Box and the aia files for the projects in the book are here: App Inventor 2 Book: Create Your Own Android Apps
How to do a lot of basic things with App Inventor are described here: How do you...? .
