Meteor DOMException: Unable to decode audio data

By Hường Hana 7:30 AM , , , Leave a Comment

EDIT : I just created a new Meteor Project and it worked :D wow.But it still doesnt work on my core project..looks like i have different settings.

In my Meteor.js project i have 4 .mp3-files located in public/sounds/xyz.mp3. I load these .mp3 with :

 let soundRequest = new XMLHttpRequest();     soundRequest.open('GET', this._soundPath, true);     soundRequest.responseType = 'arraybuffer';     let $this = this;     soundRequest.onload = function () {         Core.getAudioContext().decodeAudioData(soundRequest.response, function (buffer) {             $this.source.buffer = buffer;             $this.source.loop = true;             $this.source.connect($this.panner);         });     }; soundRequest.send();

This WORKS on google Chrome, but when i build the app via meteor run android-device, i get the following error message : DOMException: Unable to decode audio data I wonder if this is a bug because loading .png or .jpg works just fine in the mobile version. I have not installed any packages beside meteor add crosswalk but deinstalling this doesnt help either.

You shouldn't need to do a http request to get a local resource. You can just refer to a local url. On the Android device the path is different. See this code:

  function getSound(file) {     var sound = "/sounds/"+file;     if (Meteor.isCordova) {       var s;       if (device.platform.toLowerCase() === "android") {         sfile = cordova.file.applicationDirectory.replace('file://', '') + 'www/application/app' + sound;       }       else {         sfile = cordova.file.applicationDirectory.replace('file://', '') + sound;       }       var s = new Media(         sfile,         function (success) {           console.log("Got sound "+file+" ok ("+sfile+")");           s.play();         },         function (err) {           console.log("Get sound "+file+" ("+sfile+") failed: "+err);         }       );     } else {       var a = new Audio(sound);       a.play();     }   }

On a device it loads the sound file asynchronously and then plays it. In the browser it just loads and plays it synchronously.

This web API is not supported on android device but works on chrome browser of android

Check browser specification in this link https://developer.mozilla.org/en-US/docs/Web/API/AudioContext/decodeAudioData
