Hi there,I am working on a project which requires me to develop an Android App. This android app, must respond to a physical button or switch. So for example, a user would press the button, and then my app would respond accordingly.
So I am interested in
1. where can I get such a button or switch, it would have to connect via USB
2. and how would I start looking at developing my app so that it responds to a button press.
e.g. something like the buttons here would be great!
Any help much appreciated!
