Currently I am working on downloading module. Once user clicks download button, the file (either in pdf, zip file, or docx) will be downloaded from server and will be stored in local storage. I am able to download the file using FileTransfer.Download() method, but I can't open it by passing the file path.
Below is my code:
<!DOCTYPE HTML>

<head>
<meta name = "viewport" content = "user-scalable=no,width=device-width" />
<meta http-equiv="Content-type" content="text/html; charset=utf-8">

}
</style>
<script type="text/javascript" charset="utf-8">
function init() {
document.addEventListener("deviceready", ready, true);
}
function ready() {
console.log("App is ready.");
}
function download() {
// var remoteFile = "https://dl.dropbox.com/u/6731723/a.zip";
var remoteFile = "https://dl.dropbox.com/u/6731723/Beaver.pdf";
var localFileName = remoteFile.substring(remoteFile.lastIndexOf('/') + 1);
window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, function (fileSystem) {
fileSystem.root.getFile(localFileName, { create: true, exclusive: false }, function (fileEntry) {
var localPath = fileEntry.fullPath;
console.log("localPath1:" + localPath);
if (device.platform === "Android" && localPath.indexOf("file://") === 0) {
localPath = localPath.substring(7);
}
console.log("localPath2 save:" + localPath);
var ft = new FileTransfer();
ft.download(remoteFile,
localPath, function (entry) {
console.log("file path:" + entry.fullPath);
var linkopen = document.getElementById("openlink");
linkopen.style.display = "block";
linkopen.href = entry.fullPath;
// var dwnldImg = document.getElementById("dwnldImg");
//dwnldImg.src = entry.fullPath;
//dwnldImg.style.visibility = "visible";
//dwnldImg.style.display = "block";
}, fail);
}, fail);
}, fail);
}
function fail(error) {
console.log("error:" + error.code);
}
</script>
</head>
<body onload="init();">
<a href="#" onclick="download();">Download file</a>
<br />
<br />
<br />
<a href="#" id="openlink" style="display:none;font-size:larger;">open</a>
</body>
</html>

Download the java classes of example from HERE
Unzip the downloaded file in the folder " src "
Download the javascript from the example from HERE

In the Index html file. give calls to js:
<script charset="utf-8" src="main.js"> </script>
<script charset="utf-8" src="pdfviewer.js"> </script>
<script charset="utf-8" src="downloader.js"> </script>In " res / xml / plugins.xml "add:
