How to prevent a return?

Question

Android

How can I disable the return to the previous page when pressing the "Back" button on the phone?
I have a preloader in my application in front of the page, it returns to it and spins all the time

Answer 1

You can, for example, handle the backbutton event and call event.preventDefault in it

document.addEventListener("deviceready", onDeviceReady, false);
    function onDeviceReady() {
        document.addEventListener("backbutton", function (e) {
            e.preventDefault();
        }, false );
}

Answer 2

In an activity you can't go back from, override the onBackPressed() method with an empty one

@Override
    public void onBackPressed() {
        // do nothing
    }
