   @timbru31 You can find an example here: [https://www.dropbox.com/s/900pfcoouh9h9xl/mp3Player.zip?dl=0](https://www.dropbox.com/s/900pfcoouh9h9xl/mp3Player.zip?dl=0)
   
   The 700mb mp3-audio book is to big for a github-repo. Its embedded right into the app to keep the example simple.
   
   When running the app, you can click the `InitAudio` button which will read the file, and insert the native url into a <audio /> tag.
   
   ```
   function initAudioPlayer() {
     const audioEl = document.getElementById('audioEl');
     const file = cordova.file.applicationDirectory + "www/audio/ulyssess-grant.mp3";
     window.resolveLocalFileSystemURL(file, function(entry) {
       audioEl.style.display = "block"
       const nativePath = entry.toURL();
       const usedPath = window.WkWebView.convertFilePath(nativePath)
       audioEl.src = usedPath;
     })
   }
   ```
   
   If you have the memory usage open, you will see a big spike.
