Something STRANGE with Cordova media plugin

I have created a sound app for Android using Cordova. Everything was perfect, at least in the Android Studio's emulator, until I found something strange happening while testing on a real device.
My app contains more than 100 sounds one second each. You click to play sounds till you get 32 clicks that play audios without problems. But starting from thirty-third (33rd) click I get a message error:
code: -19 message: undefined
I must mention that you can reply the previous clicked sounds that still work. But other sounds get the error above.
If I close and reopen the app, sounds that gave error work again until I get to 33rd click and start getting the error message even for sounds that used to work.
Here is the code I use to play my sounds:
// Wait for device API libraries to load
//
document.addEventListener("deviceready", onDeviceReady, false);
// device APIs are available
//
function onDeviceReady() {
var my_media = new playAudio();
}
// Audio player
//
var my_media = null;
var mediaTimer = null;
// Play audio
//
my_media = {}; // init the play object
function playAudio(src, id) {
if (!my_media[id]) { // check if media already created
my_media[id] = new Media(src, onSuccess, onError);
}
my_media[id].play();
}
//playAudio('file:///android_asset/www/media/1.mp3');
// Pause audio
//
function pauseAudio() {
if (my_media) {
my_media.pause();
}
}
// Stop audio
//
function stopAudio() {
if (my_media) {
my_media.stop();
}
clearInterval(mediaTimer);
mediaTimer = null;
}
// onSuccess Callback
//
function onSuccess() {
console.log("playAudio():Audio Success");
}
// onError Callback
//
function onError(error) {
alert('code: ' + error.code + '\n' +
'message: ' + error.message + '\n');
}
// Set audio position
//
function setAudioPosition(position) {
document.getElementById('audio_position').innerHTML = position;
}
Any IDEA?
thanks

Phonegap Build App - Play Audio

So, i have made an app with phonegap build, where the goal is to read a xml file that contains info about audio tracks, and includes the path for each audio track.
I proceed to input the data of xml file into html, and before it was working fine. After i imported my project into phonegap build, no more audio plays. The controls work, but the audio doesn't play.
Here is the code:
<script>
document.addEventListener('play', function(e){
var audios = document.getElementsByTagName('audio');
for(var i = 0, len = audios.length; i < len;i++){
if(audios[i] != e.target){
audios[i].pause();
}
}
}, true);
xmlhttp=new XMLHttpRequest();
xmlhttp.open("GET","teste.xml",false);
xmlhttp.send();
xmlDoc=xmlhttp.responseXML;
document.write("<table><tr><th>Track</th><th>Description</th<th>URL</th></tr>");
var x=xmlDoc.getElementsByTagName("CD");
for (i=0;i<x.length;i++){
document.write("<tr><td>");
document.write(x[i].getElementsByTagName("TITLE")[0].childNodes[0].nodeValue);
document.write("</td><td>");
document.write(x[i].getElementsByTagName("DESCRIPTION")[0].childNodes[0].nodeValue);
document.write("</td><td>");
var audio = x[i].getElementsByTagName("URL")[0].childNodes[0].nodeValue;
document.write('<audio controls><source src="'+audio +'" type="audio/mpeg"></audio>');
document.write("</td></tr>");
}
document.write("</table>");
</script>
The XML file is simply structured like this:
<CD>
<TITLE>Track one</TITLE>
<DESCRIPTION>Bob Dylan</DESCRIPTION>
<URL>files/test.mp3</URL>
</CD>
I have read some similar questions and find that most mistakes are in the PATH of the audio file. What should i do for the audio to play?
Thanks
EDIT: I have updated my code:
var path = '/android_asset/www/';
var audio = x[i].getElementsByTagName("URL")[0].childNodes[0].nodeValue;
var audioPath = path+audio;
alert(audioPath);
document.write('PLAY<br/>');
document.write('PAUSE<br/>');
document.write('STOP');
document.write('<p id="audio_position"></p>');
The alert(audioPath) returns the correct path and it works when I use this function:
function onDeviceReady() {
playAudio('/android_asset/www/files/test1.mp3');
}
The audioPath is the same as the path above.
But the app doesn't play the sound when i press Play...
Any ideas?
playAudio function:
function playAudio(src) {
// Create Media object from src
my_media = new Media(src, onSuccess, onError);
// Play audio
my_media.play();
// Update my_media position every second
if (mediaTimer == null) {
mediaTimer = setInterval(function() {
// get my_media position
my_media.getCurrentPosition(
// success callback
function(position) {
if (position > -1) {
setAudioPosition((position) + " sec");
}
},
// error callback
function(e) {
console.log("Error getting pos=" + e);
setAudioPosition("Error: " + e);
}
);
}, 1000);
}
}
FOUND my problem! It was the 'onclick'. I now import jQuery and built the following code:
$(".btPlay").on("click",function (e) {
// body...
console.log("Play");
playAudio(audioPath);
});
It now works!

Try to install the cordova Media plugin org.apache.cordova.media (http://docs.phonegap.com/en/edge/cordova_media_media.md.html)
And then, try this :
//src is your path to your file
var my_media = new Media(src, function(){
alert("Success");
}, function(){
alert("Fail");
});
my_media.play();
Try it with all the paths yuo already tried, but this plugin works for me with online files.
EDIT: You may need to add '/android_asset/www/' in front of your src

Try to add /android_asset/www/ before file path. As I remember android need absolute path to file. So you code should be like this
playAudio("/android_asset/www/song/Banjaara.mp3");
Ofcourse if song folder is in your main html directory.

unable to play audio recordings on android using phonegap 2.4

im trying to record an audio file using Media object in phonegap and then play it. i have no problem recording, but then when i try to play it my app shuts down, both on my emulator and my device. on the logcat it says: "null pointer exception at org.apache.cordova.readyPlayer (AudioPlayer.java)". many thanks to anyone who is willing to help me, it took me a while to realize im completely lost here.
here is the code which i copied from http://docs.phonegap.com/en/2.4.0/cordova_media_media.md.html#media.stopRecord and added .play() after the .stopRecord(). i can add the manifest and activity if needed, i doubt that the problem is there but i could be wrong.

// Record audio
mediaRec.startRecord();

setAudioPosition(recTime + " sec");

I found the same issue with Cordova 3.5 (with Media plugin 0.2.11) and Android 4.4. The solution is as described above. Basically something like this should do the trick:
mediaRec.stopRecord();
src = mediaRec.src; // if you don't have src defined anymore
mediaRec.release();
mediaPlay = new Media(src, onSuccess, onError);
mediaPlay.play();

There is no need to create an other Media object to play the previously recorded file. Just do the following - you have to release the media object after recording is stopped:
// variable in global scope
var mediaRec = 0;
// function to record an audio
function recordAudio() {
// create media object for your recording
mediaRec = new Media("phonegap_rec.amr", onMediaRecordSuccess, onMediaRecordError);
// start recording
mediaRec.startRecord();
// recording for 5 seconds
var recTime = 0;
var recInterval = setInterval(function() {
recTime = recTime + 1;
if (recTime >= 5) {
clearInterval(recInterval);
// stop recording after 5 seconds
mediaRec.stopRecord();
// release the media object (THIS IS THE KEY SOLUTION HERE)
mediaRec.release();
}
}, 1000);
}
// function to playback recorded audio
function playRecord() {
// check if the object exists
if (mediaRec) {
// now you can playback the recording
mediaRec.play();
}
}

phonegap Media Error code 0

first time when i play a mp3 file using phonegap media it works fine. but wen i stop and again play for 2nd time it does not and 3rd time when i play it shows error code 0
below is code
var my_media = null;
var mediaTimer = null;
var pausePos = 0;
var counter=0;
var playing=false;
function playAudio(src) {
// Create Media object from src
if(my_media==null){
my_media = new Media(src, onSuccess, onError);
}
if(!playing){
// get audio duration
var duration = my_media.getDuration();
// set slider data
if( duration > 0 ){
$('#slider').attr( 'max', Math.round(duration) );
$('#slider').slider('refresh');
}
// Play audio
my_media.play();
playing=true;
$("#play_pause_img").attr("src","img/pause.png")
// Update my_media position every second
if (mediaTimer == null) {
mediaTimer = setInterval(function() {
// get my_media position
my_media.getCurrentPosition(
// success callback
function(position) {
if (position > -1) {
setAudioPosition(position);
}
},
// error callback
function(e) {
console.log("Error getting pos=" + e);
setAudioPosition("Error: " + e);
}
);
}, 1000);
}
}
else{
pauseAudio();
playing=false;
$("#play_pause_img").attr("src","img/play.png");
}
}
function pauseAudio() {
if (my_media) {
my_media.pause();
}
}
function resumeAudio()
{
my_media.play();
}
function stopAudio() {
if (my_media) {
my_media.stop();
my_media.release();
playing=false;
$("#play_pause_img").attr("src","img/play.png");
}
clearInterval(mediaTimer);
mediaTimer = null;
pausePos = 0;
$('#slider').val(pausePos);
$('#slider').slider('refresh');
}
function onSuccess() {
console.log("playAudio():Audio Success");
}
function onError(error) {
alert('code: ' + error.code + '\n' +
'message: ' + error.message + '\n');
}
what could be the reason and what is error code 0.

In 3.5.0 I'm experiencing the error function firing with an error code of 0.
From older docs, 0 appears to mean none, and appears to be no indication of a problem.
I seems under these circumstances this can be ignored, and is not really an error

it has to do with audio-ressources which are finite and therefore must get released. This is explained there: http://docs.phonegap.com/en/3.3.0/cordova_media_media.md.html
In my case it did the trick to call release() for my media object at that moment I don't use it anymore - I do it directly after calling stop()
this.stopAudio = function() {
if (my_media) {
my_media.stop();
my_media.release();
}
}

I have the same problem. I'm searching for the solution, but I didn't find anything.
My code:
$('#button').click(function{
media = new Media('/android_asset/www/sonidos/trans/sound.m4a', play, error);
});
function play(){
media.play();
}
function error(err){
alert(err.code);
}
If i do in that way, the sound does not play and I get always the alert with 0. That not match with any error code from mediaError.
Testing and testing I make code works with next code:
$('#button').click(function{
media = new Media('/android_asset/www/sonidos/trans/sound.m4a', play, error);
media.play();
});
function play(){
;
}
function error(err){
;
}
I know is not the correct way but I can't find other solution.
P.D. Sorry for my bad English.

Add the release method in the onSuccess method in addition to the stop method you created.
function onSuccess() {
my_media.release();
console.log("playAudio():Audio Success");
}
