PhoneGap Filesystem Example

filesystem.js

/**
 *  Prepare the App Folder 
 */
(function(){
	window.appRootDirName = ".myapp";
	document.addEventListener("deviceready", onDeviceReady, false);

	function onDeviceReady() {
		console.log("device is ready");
		window.requestFileSystem  = window.requestFileSystem || window.webkitRequestFileSystem;
		window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, gotFS, fail);
	}
	
	function fail() {
		console.log("failed to get filesystem");
	}

	function gotFS(fileSystem) {
		console.log("filesystem got");
		fileSystem.root.getDirectory(window.appRootDirName, {
			create : true,
			exclusive : false
		}, dirReady, fail);
	}

	function dirReady(entry) {
		window.appRootDir = entry;
		console.log(JSON.stringify(window.appRootDir));
	}
})();

imageutil.js

function downloadImage(url, success, err){
	console.log('download image ' + url);
	
	var fileName = new Date().getTime() + ".png";
	ft = new FileTransfer();
	ft.download(
	    url,
	    window.appRootDir.fullPath + "/" + fileName,
	    function(entry) {
	        console.log("download complete: " + entry.fullPath);
	        success(entry.fullPath);
	    },
	    function(error) {
	        console.log("download error source " + error.source);
	        console.log("download error target " + error.target);
	        console.log("upload error code" + error.code);
	        err(error);
	    }
	);
}

very nice! Didnt see root.getDirectory anywhere in the docs so was having some trouble getting the sd card location. Works in Cordova 2.0!

Excellent! .Thank you very much for shearing this valuable code.

I believe that in Phonegap 3, the appRootDirName is no longer needed.

i am using cordova 3.3.0. I am able to play a local file (stored in app /www folder) in android. But for ios it will return the error "cannot play this file ....".

Reply me how to mention the local file (audio) path in ios. ?

We have implemented filesystem.js in cordova application which is getting into fail callback function for Android Version Marshmallow 6.0.1.
Could you please help us to know is there any option to resolve this issue??

exclusive : false means what?

@charyorde take a look there https://www.youtube.com/watch?v=15QSf-hC8us
