Cordova/PhoneGap exit app after twice press back button with toast ( plugin required https://github.com/EddyVerbruggen/Toast-PhoneGap-Plugin )

app-exit.js

var lastTimeBackPress=0;
var timePeriodToExit=2000;

function onBackKeyDown(e){
    e.preventDefault();
    e.stopPropagation();
    if(new Date().getTime() - lastTimeBackPress < timePeriodToExit){
        navigator.app.exitApp();
    }else{
        window.plugins.toast.showWithOptions(
            {
              message: "Press again to exit.",
              duration: "short", // which is 2000 ms. "long" is 4000. Or specify the nr of ms yourself.
              position: "bottom",
              addPixelsY: -40  // added a negative value to move it up a bit (default 0)
            }
          );
        
        lastTimeBackPress=new Date().getTime();
    }
};

document.addEventListener("backbutton", onBackKeyDown, false);

To disable the default behavior of the back button on android devices simply register an event handler for the back button. This would prevent the back button from closing the application.

Code shown below is specifically for Framework7

$(document).on('page:beforeinit', function (e) {
if( $.fn.hyellaIMenu.mainView.history && $.fn.hyellaIMenu.mainView.history.length > 1 ){
    document.addEventListener( "backbutton", disableBackButton, false );
}
});

function disableBackButton( e ){
    if( $.fn.hyellaIMenu.mainView.history && $.fn.hyellaIMenu.mainView.history.length < 3 ){
        document.removeEventListener("backbutton", disableBackButton );
    }

if( $.fn.hyellaIMenu.mainView.history && $.fn.hyellaIMenu.mainView.history.length > 1 ){
    $.fn.hyellaIMenu.mainView.router.back();
}
};

To override the default back-button behavior, register an event listener for the backbutton event.

NOTE: It is no longer necessary to call any other method to override the back-button behavior.

Hi, I'm using google translate to send you the message. Anyway, I've reused your "app-exit.js" script. Worked perfectly. So, how can I do it when my modal materialize is open, can not quit the application? If the modal is not open, you can quit the application. And that the user exits the modal only by the option of the exit button of the modal itself?
