When problems like this show up, I start to use any kind of a JavaScript framework. Those frameworks are build to avoid problems with different browsers. To catch all different keypress() apis, like the link from Emmett shows, can be very difficult. Example: In HTML head: <script src=”http://code.jquery.com/jquery-1.4.4.js”></script> In the JS tag: $(document).keydown(function(event) { alert(‘You … Read more
Ok. I finally figured how to do what I want, and I am not proud on Android for this. I am writing server/client application where on client I have to open SoftKeyboard and send pressed keys (characters and DEL key)… Each time key is pressed, that character is sent to server.

Keep it simple. Use both onKeyPress() and onKeyUp(): <input id=”edValue” type=”text” onKeyPress=”edValueKeyPress()” onKeyUp=”edValueKeyPress()”> This takes care of getting the most updated string value (after key up) and also updates if the user holds down a key. jsfiddle: http://jsfiddle.net/VDd6C/8/

With plain Javascript, the simplest is: document.onkeypress = function (e) { e = e || window.event; // use e.keyCode }; But with this, you can only bind one handler for the event. In addition, you could use the following to be able to potentially bind multiple handlers to the same event: addEvent(document, “keypress”, function (e) … Read more
Remove your key listener or return true when you have KEY_BACK. You just need the following to catch the back key (Make sure not to call super in onBackPressed()). Also, if you plan on having a service run in the background, make sure to look at startForeground() and make sure to have an ongoing notification … Read more
