300ms delay on Android devices


Recommended Posts

Hello guys, I've a problem with "touchstart" event on android devices.


The touch event is detected 300ms later, and this cause a lot of problems.


I tried to solve using a meta tag:

<meta name="viewport" content="width=device-width, user-scalable=no">

but nothing, so I tried to download and configure a library ( https://github.com/ftlabs/fastclick ):

<script type="text/javascript" src="src/other/jquery-2.1.1.min.js"></script><script type="text/javascript" src="src/other/fastclick.js"></script><script type="text/javascript">    $(document).ready(function(){                $(function() {          FastClick.attach(document.body);        });        });</script>

but nothing, anyone can help me to solve this issue?

yeah, this is my function (I used this on iOS with perfect result):

this.sprite.touchstart = this.sprite.click = function() {                                                                      if (game.system.paused != true) {                                                                      this.remove();                                                                      if (killHundred < 100) {                                                                      killHundred = killHundred + 1;                                                                      game.storage.set("killHundred", killHundred)                                                                      }                                                                      expNum = Math.floor(Math.random() * 2) + 1;                                                                      if (audioState == 0) {                                                                      if (expNum == 1) {                                                                      game.audio.playSound("laugh")                                                                      } else {                                                                      if (expNum == 2) {                                                                      game.audio.playSound("laugh1")                                                                      }                                                                      }                                                                      }                                                                      score = score - 10;                                                                      if (score < 0) {                                                                      score = 0                                                                      }                                                                      scoreText.setText(score.toString());                                                                      scoreText.updateTransform();                                                                      scoreText.position.x = 20;                                                                      scoreText.position.y = 20;                                                                      this.spriteAnimation = new game.Animation("objects/bubbles/obj-exp-evil_01.png", "objects/bubbles/obj-exp-evil_02.png", "objects/bubbles/obj-exp-evil_03.png", "objects/bubbles/obj-exp-evil_04.png", "objects/bubbles/obj-exp-evil_05.png", "objects/bubbles/obj-exp-evil_06.png");                                                                      this.spriteAnimation.position.set(this.position.x, this.position.y);                                                                      this.spriteAnimation.anchor.set(0.5, 0.5);                                                                      this.spriteAnimation.scale.set(0.8, 0.8);                                                                      this.spriteAnimation.animationSpeed = 0.1;                                                                      this.spriteAnimation.loop = false;                                                                      this.spriteAnimation.play();                                                                      game.scene.stage.addChild(this.spriteAnimation);                                                                      }                                                                      }

And this is the screenshot (61fps, really nice): http://oi61.tinypic.com/2i7plrc.jpg

At the moment I tried with no results adding a preventDefault() function here:

a.touchstart = a.click = function(event){[...my code...]event.preventDefault();}

Than I tried with:

<script type="text/javascript">      window.addEventListener( "load", function() {        FastClick.attach( document.body );      }, false );</script>

instead of jQuery way without any results...


@enpu if you need the APK I can send it to you. Let me know ^_^

I made other tests on other devices.


Working Devices:

- MotoG 2nd Generation 2014, Android 4.4.4

- Galaxy Note 10.1

- HTC Sensation, Android 4.0.3 (Thank you Oddskill)


Not Working Devices (Latency on Touchevents):

- Galaxy Note 8", Android 4.4.2

- Acer liquid Z3 Duo, Android 4.2

- Samsung Galaxy S3 (gt-I9300) Android 4.3.2


If you want to try the alpha version, download this APK. It's not optimized, because I'm trying to solve the latency issue before convert the sound and change the sprite.


(Please if you write a feedback, add your device specifications)
