Answer 1

this is just alternet way to achieve goal to play audio from html file in android . because android 2.2 do not have support for audio tag of HTML5.

use Mediaplayer ( http://developer.android.com/reference/android/media/MediaPlayer.html ) of Android for playing audio. you can invoke function of android from javascript that you have written in HTML file..

this is example of how you can invoke function written in java file from javascript code (insted of ShowAndroidToast function, you can write code to play audio using mediaplayer object.)

  WebView webView = (WebView) findViewById(R.id.webview);
    webView.addJavascriptInterface(new WebAppInterface(this), "Android");
    --------------------------------
    public class WebAppInterface {

        Context mContext;
        /** Instantiate the interface and set the context */
        WebAppInterface(Context c) {
            mContext = c;
        }

        /** Show a toast from the web page */
        @JavascriptInterface
        public void showToast(String toast) {
            Toast.makeText(mContext, toast, Toast.LENGTH_SHORT).show();
        }
    }

    ---------------------------
    java sript code

    <input type="button" value="Say hello" onClick="showAndroidToast('Hello Android!')" />

    <script type="text/javascript">
        function showAndroidToast(toast) {
            Android.showToast(toast);
        }
    </script>

This way you invoke audio from Android code.

Answer 2

The Android(WebKit) 2.2 default browser technically supports HTML5 audio but it can't play any media files encoded with popular codecs. Because of browser vendors' inconsistent implementations of the HTML5 audio tag, you'll need to use JavaScript to accurately determine whether you can use native audio or a fallback.
