PhoneGap Android LowLatencyAudio plugin doesn't work
Question
I'm building a mobile game with HTML5 and Javascript, for Android devices.
Android doesn't support HTML5 Audio, that's why i've choose to use a phonegap plugin : https://github.com/phonegap/phonegap-plugins/tree/master/Android/LowLatencyAudio
My structure is very simple, i've got 3 objects.
- game, which is my main object.
- animation, which is my object where are all my sprites animations.
- sound, which all my sound are played, looped or stopped.
Here, my index.html file :
<!DOCTYPE HTML>
<html>
<head>
<title>Test</title>
<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no;" />
<meta charset="UTF-8" />
<link rel="stylesheet" type="text/css" href="assets/css/style.css">
<script type="text/javascript" charset="UTF-8" src="cordova.js"></script>
<script type="text/javascript" charset="UTF-8" src="PGLowLatencyAudio.js"></script>
<script type="text/javascript" charset="UTF-8" src="assets/js/src/pixi.js"></script>
<script type="text/javascript" charset="UTF-8" src="assets/js/game.js"></script>
<script type="text/javascript" charset="UTF-8" src="assets/js/sound.js"></script>
<script type="text/javascript" charset="UTF-8" src="assets/js/animation.js"></script>
<script type="text/javascript" charset="UTF-8">
function onDeviceReady(){
PGLowLatencyAudio.preloadFX('drum','assets/son/drum/drumPiste1.mp3', game.sound.successHandler, game.sound.errorHandler);
};
function onBodyLoad(){
document.addEventListener("deviceready",onDeviceReady,false);
};
</script>
</head>
<body onload="onBodyLoad()">
<div id="wrapper"></div>
<script type="text/javascript" charset="UTF-8">
game.init();
game.sound.init();
game.animation.init();
</script>
</body>
I'm using the PGLowLatencyAudio.preloadFX function of the plugin, to preload my mp3 file.
After, I call my init function of my object sound, which is like that :
game.sound = {
init: function(){
soundsArray = [];
game.sound.playSound();
},
successHandler: function(result){
alert(result);
},
errorHandler: function(error){
alert(error);
},
playSound: function(){
PGLowLatencyAudio.play('drum', game.sound.successHandler, game.sound.errorHandler);
},
};
In my init function, i call my playSound function, to play the sound i've previously preload.
It try to play sound before preload, but i don't understand why.
Error message is : A reference does not exist for the specified audio id .
