Play Sound in WebView Using JavaScript

I am trying to play sound from JavaScript code loaded in a WebView from assets:

WebView web_view = (WebView) findViewById(R.id.web_view);
web_view.getSettings().setJavaScriptEnabled(true);
web_view.setWebChromeClient(new WebChromeClient());
web_view.loadUrl("file:///assets/www/index.html");

I tried all combinations of the following ways, how to play audio with OGG, MP3 and WAV files, JavaSrcipt code is in assets /www/js/play.js:

audio = new Audio("../audio/sound.mp3");
audio.load();
audio.play();

audio = new Audio("./audio/sound.mp3");
audio.load();
audio.play();

audio = new Audio("audio/sound.mp3");
audio.load();
audio.play();

audio = new Audio("file:///android_asset/www/audio/sound.mp3");
audio.load();
audio.play();

audio = new Audio();
audio.src = document.getElementById("audio_tag").src;
audio.load();
audio.play();

Where audio_tag <audio id="audio_tag" src="audio/sound.mp3" preload="auto"></audio>is also used with all combinations of paths and formats.

But the sound does not play and only tells you what might be wrong, this is the following general error:

E / MediaPlayer (1530): error (1, -2147483648)

Guessing from this informational message, the path to the sound file should be correct for the second fifth case:

I/StagefrightPlayer(33): setDataSource('file:///android_asset/www/audio/sound.mp3');

Android WebView, javascript, , shouldOverrideUrlLoading , .

- , , ?

It depends on your Android device and the available codecs ... But probably the path is wrong. Do you use Phonegap? Does your code play in desktop browsers?

I use similar code:

var myAudio = document.getElementsByTagName('audio')[0];
myAudio.pause();
myAudio.src = file;
myAudio.play();

And my HTML sound tag:

<audio id="audio" src="" type="audio/mpeg" preload="metadata" ontimeupdate="timeUpdate()"
   ondurationchange="durationChange()" onerror="musicError()" onended="musicEnded()">
<embed src="" height=50 width=100></embed>

I use the mp3 audio file format because it works for iOS and some Android devices.

Also note that the Audio tag element is not available for all versions of Android. As you can see here , it works for Android 2.3 and above.
