Android Back Button - Current Wisdom

What is the current wisdom for a native app (javascript/Voltbuilder) that needs to make the Android Back Button cause the app to go to the Previous Screen?

Thank you,

Since my post I have found that this code disables the Back Button. It works in my AppStudio native app.

$(document).ready(function () {
document.addEventListener(“backbutton”, function() {}, false);
});
