Android: Playing an Asset Sound Using WebView

Question

I am trying to play a sound from the assets folder when a user clicks on an tag on my application\'s WebView. I found that I can use a new class extending WebViewClient to

Where you declare your MediaPLayer in MyWebViewClient, add the following...

public class MyWebViewClient extends WebViewClient{

    public MediaPlayer mp;
    private Context context = null; // Add this line

    ...
}

Then add a constructor to MyWebViewClient as follows...

public MyWebViewClient(Context context) {
    this.context = context;
}

Then in shouldOverrideUrlLoading(...) get your assets as follows...

AssetFileDescriptor afd = context.getAssets().openFd(url);

In your MainActivity set the WebViewClient by passing this (which is the Activity Context) as follows...

webMain.setWebViewClient(new MyWebViewClient(this));

Also you should return false from shouldOverrideUrlLoading(...) if the url ends with '.mp3' - this shows your WebView is handling things and the 'host' application should not start an instance of the stock web browser.

EDIT: To play audio files from the assets directory, you need to set the data source differently - see the accepted answer to play-audio-file-from-the-assets-directory.

Also you should call mp.prepare() before calling mp.start().
