I am using bootstrap typeahead.
It depends on this jQuery code to work:
el.on('keyup', doSomething() )
On Chrome on Windows it works fine. On Chrome on Android it doesn't. The keyup event is never fired. The element to which it is bound definitely has the focus.
This appears to be a recent development.
Chrome 28.0.1500.64 Android 4.1.2 SGP321 Build/10.1.1.A.1.307

I came across this same problem earlier today. How can android chrome not support these key events! I assume you've found a workaround by now, but here's a fix that I came up with for now.
function newKeyUpDown(originalFunction, eventType) {
return function() {
if ("ontouchstart" in document.documentElement) { // if it's a touch device, or test here specifically for android chrome
var $element = $(this), $input = null;
if (/input/i.test($element.prop('tagName')))
$input = $element;
else if ($('input', $element).size() > 0)
$input = $($('input', $element).get(0));
if ($input) {
var currentVal = $input.val(), checkInterval = null;
$input.focus(function(e) {
clearInterval(checkInterval);
checkInterval = setInterval(function() {
if ($input.val() != currentVal) {
var event = jQuery.Event(eventType);
currentVal = $input.val();
event.which = event.keyCode = (currentVal && currentVal.length > 0) ? currentVal.charCodeAt(currentVal.length - 1) : '';
$input.trigger(event);
}
}, 30);
});
$input.blur(function() {
clearInterval(checkInterval);
});
}
}
return originalFunction.apply(this, arguments);
}
}
$.fn.keyup = newKeyUpDown($.fn.keyup, 'keyup');
$.fn.keydown = newKeyUpDown($.fn.keydown, 'keydown');
Sorry to say this but keyup/keydown events do not work for chrome browser in android. There are other people who have reported this issue(Here and Here) from last 1 year and its not fixed yet. so it's better for developers to avoid using these events till it gets fixed.
