WP7: play MP3 using Media with phonegap/Cordova
- by Loda
My problem:
I use the Media Class from Cordova.
The MP3 file is only played once (the first time).
Code:
Add this code to the Cordova Starter project to reproduce my problem:
var playCounter = 0;
function playMP3(){
console.log("playMP3() counter " + playCounter);
var my_media = new Media("app/www/test.mp3");//ressource buildAction == content
my_media.play();
playCounter++;
}
[...]
<p onclick="playMP3();">Click to Play MP3</p>
VS output:
[...]

My Config:
cordova-1.6.1.js
Lumia 800
WP 7.5 (7.10.7740.16)
WorkAround (kind of):
Desactivate the app (turn off the screen)
reactivate the app (turn on the screen)
- you get one more shot.
Any help is welcome as I am blocked on this since may days and I found no usefull information anywhere.
Also, Can you tell me if this code work on your config ?

Update: add a demo code
using a global var. Keeping the instance alive.
result
The test2.mp3 is played and can replay fine.
the test.mp3 is not played at all.
It is the first file you play that will work.
Code
function onDeviceReady()
{
document.getElementById("welcomeMsg").innerHTML += "Cordova is ready! version=" + window.device.cordova;
console.log("onDeviceReady. You should see this message in Visual Studio's output window.");
my_media = new Media("app/www/test.mp3");//ressource buildAction == content
my_media2 = new Media("app/www/test2.mp3");//ressource buildAction == content
}
var playCounter = 0;
var my_media = null;
function playMP3(){
console.log("playMP3() counter " + playCounter);
my_media.play();
playCounter++;
}
var my_media2 = null;
function playMP32(){
console.log("playMP32() counter " + playCounter);
my_media2.play();
playCounter++;
}
