Normal keypress event does not give keyCode in android device. There has already been a big discussion on this.

If you want to capture the press of space bar or special chars, you can use keyup event.

$('#input').on('keyup', e => {
     var keyCode = e.keyCode || e.which;
     if (keyCode == 0 || keyCode == 229) { 
         keyCode = e.target.value.charAt(e.target.selectionStart - 1).charCodeAt();             
     }
})

just check your input characters keyCode, if it is 0 or 229 then here is the function getKeyCode which uses charCodeAt of JS to return the KeyCode which takes input string a parameter and returns keycode of last character.

<script>
        var getKeyCode = function (str) {
            return str.charCodeAt(str.length);
        }


        $('#myTextfield').on('keyup',function(e){

            //for android chrome keycode fix
            if (navigator.userAgent.match(/Android/i)) {

                var inputValue = this.value;

                var charKeyCode = e.keyCode || e.which;
                if (charKeyCode == 0 || charKeyCode == 229) { 
                    charKeyCode = getKeyCode(inputValue);
                    alert(charKeyCode+' key Pressed');
                }else{
                   alert(charKeyCode+' key Pressed');
                    }
            }       
        });
    </script>
