title: Detect use of Android back button using JavaScript
body: <p>My site has breadcrumbs which highlight which stage in a process the user has reached. The breadcrumbs rely on the browser history to tell which stage should be highlighted when the browser back button is used, but on Android devices using the hardware back button this seems to be bypassed and the highlighted breadcrumb does not change. </p>
  
  <p>My site is not using PhoneGap or anything similar as it's not usually a mobile site, so is it possible to capture use of the Android back button so that I can add an event to set the breadcrumb highlight based on the history log when the button is used, just using JavaScript or jQuery?</p>
