Include the given code just above the </head> tag in your index.html . Here we use FileTransfer object and fileTransfer.download() method.

  <script type="text/javascript" charset="utf-8">  
       // Wait for Cordova to load  
    document.addEventListener("deviceready", onDeviceReady, false);  
    // Cordova is ready  
    function onDeviceReady() {  
      alert("Going to start download");  
      downloadFile();  
    }  
     function downloadFile(){  
       window.requestFileSystem(  
                    LocalFileSystem.PERSISTENT, 0,  
                    function onFileSystemSuccess(fileSystem) {  
                    fileSystem.root.getFile(
