Hello,

my_media.play() isn't playing any sounds. App is a small game for toddlers and some sound effects must be reproduced at certain points during program execution. Made sure no my_media.play() is called before Cordova is fully loaded (first call to my_media.play() is made inside the OnDeviceReady callback function by means of the playAudio() function), however no sound is ever played.

Checked the provided example in the "samples" section but frankly speaking that example ends up being more an OOP tutorial than a real world example on how to use the Cordova's Media object. For example, contrary to the sample, many times in games sounds come packaged with the app, so in that case how are you supposed to reference the location of such file? If you check Cordova's docs, it specifies something like "/android_asset/www/soundsfolder/sound.mp3", but that's when you create a stand-alone Cordova/PhoneGap project.

So the question is how do you reference the location of sound files in an Icenium project? The file format must be .wav or .mp3?

Your help will be appreciated.

Alfredo.

Steve,

No, my device is a Motorola Defy 526 running 2.3.5 . After several hours of head-banging and hair-pulling this is the code that actually worked:

function playAudio(src) {

// HTML5 Audio
if (typeof Audio != "undefined") {
new Audio(src).play() ;

// Phonegap media
} else if (typeof device != "undefined") {

// Android needs the search path explicitly specified
if (device.platform == 'Android') {
src = '/android_asset/www/' + src;
}

var mediaRes = new Media(src,
function onSuccess() {
// release the media resource once finished playing
mediaRes.release();
},
function onError(e){
console.log("error playing sound: " + JSON.stringify(e));
});
mediaRes.play();

} else {
console.log("no sound API to play: " + src);
}
}

That is, plain javascript is what's actually working (new Audio(src).play() ;) Works in the Mist simulator and works on the Android device. I'm about to test it in Android 4.1 and above 'cause some say this is not working on these devices.

Hi, Alfredo

You are a cordova pioneer! thank you for help me to use the cordova audio plugin.

But giving you an easier alternating way to play audio: that is using HTML's audio playing method.

And could you tell me whether your this method is really sometimes using cordova audio plugin?

Because my last time debug shows that the in the "var mediaRes = new Media(src, ..." , Media is

unrecognized, I wonder whether the Media function is claimed in cordova.js or plugin.js?

Would you like to tell me what is the Javasript's method to claim using an outside var? is it just include

by <script src=> or other method like import in Java?

Hello George,

The Media API is provided by a Cordova plugin which we have integrated in AppBuilder clients as a Core plugin and you can enable it from Properties > Plugins page. This is all you have to do. No references are required in order to use it further. Just note that when using any plugin's API you will have to call it in deviceready callback function.

As for your subsequent question, AppBuilder provides two options that let you debug your app - in our Simulator and on device.
