Not able to exit phonegap application on Back Button of android device

Question

I have used following code to exit from application. For first time it works perfectly. But when I opened some next screens and then came back to screen where I wanted to close my application, it fails to close application.

<script type="text/javascript" src="cordova.js"></script>
<script type="text/javascript">

function onLoad() 
    {
        document.addEventListener("deviceready", onDeviceReady, false);
        //alert("Load");
    }

    function onDeviceReady() 
    {
        document.addEventListener("backbutton", onBackKeyDown, true);
       // alert("Device Ready");
    }


    function onBackKeyDown() 
    {
        navigator.app.exitApp();        
    }
</script>

Please suggest something which will work ....

Have you tried binding deviceready out of onload? deviceready fires as soon as the phonegap api are loaded so it may fire even before your onLoad function executes — Taimour Tanveer, Apr 16 '14 at 16:10

You should delete navigation history on page load so whenever you press the back button it will exit the app automatically.

        if (typeof navigator.app !== 'undefined') {
            navigator.app.clearHistory();
        }

Above code will work. Since navigator.app is undefined for iOS, this will work cross platform.
