read uploaded vcf file from server

I have uploaded vcf file successfully on server on getting help from my previous question (the one which is edited)
Now I need a help in how to read that vcf file or vcard from server and display as a contact number and contact name in my phonegap app.
plugin used cordova-plugin-file-transfer
Can anyone help on this ?

Using plugin cordova-plugin-file-transfer https://github.com/apache/cordova-plugin-file-transfer you can download file from server.
For Read vcf file, you need https://github.com/nilclass/vcardjs JavaScript based library. you can directly use .js files.
You can follow below example.
window.requestFileSystem(window.TEMPORARY, 1 * 1024 * 1024, function (fs) {
console.log('file system open: ' + fs.name);
var fileName = "temp.vcf";
var dirEntry = fs.root;
dirEntry.getFile(fileName, { create: true, exclusive: false }, function (fileEntry) {
download(fileEntry,"server-path-to-file.vcf");
}, onErrorCreateFile);
}, onErrorLoadFs);
function download(fileEntry, uri) {
var fileTransfer = new FileTransfer();
var fileURL = fileEntry.toURL();
fileTransfer.download(
uri,
fileURL,
function (entry) {
console.log("Successful download...");
console.log("download complete: " + entry.toURL());
readFile(entry);
},
function (error) {
console.log("download error source " + error.source);
console.log("download error target " + error.target);
console.log("upload error code" + error.code);
},
null, // or, pass false
{
//headers: {
// "Authorization": "Basic dGVzdHVzZXJuYW1lOnRlc3RwYXNzd29yZA=="
//}
}
);
}
function readFile(fileEntry) {
fileEntry.file(function (file) {
var reader = new FileReader();
reader.onloadend = function () {
console.log("Successful file read: " + reader.result);
reader.parseVCard(reader.result);
};
reader.readAsText(file);
}, onErrorReadFile);
}
function parseVCard(vCarddata){
VCF.parse(vCarddata, function(vcard) {
// this function is called with a VCard instance.
// If the input contains more than one vCard, it is called multiple times.
console.log("Formatted name", vcard.fn);
console.log("Names", JSON.stringify(vcard.n));
});

phonegap android cannot read image file

I am developing hybrid using phonegap 3.3. I am using camera plugin to capture image and store into photo album which working fine. Later, I have to read image file from the device storage.
I am using the following code.
window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, gotFS, failFS);
function gotFS(fileSystem){
fileSystem.root.getFile(imageData, {create: true}, gotFileEntry, fail);
}
function gotFileEntry(){
fileEntry.file(gotFile,fail);
}
function gotFile(file){
alert(file.getParent().fullPath);
}
I am getting error in the first line. It is giving
FileError.ENCODING_ERR
I am not sure what I am doing wrong here. After, I have to move to another directory with new name. Could anyone help me to fix.
I am using camera plugin for capture images and file plugin to read files and directory.

You can try with below code to capture and copy image
var pictureSource;
var destinationType;
var FileFolder = "";
var FileName = "";
var obj_imageCapture = {
capturePicture:function(imgFolder,imgName)
{
var image = imgFolder + imgName;
FileFolder = imgFolder;
FileName = imgName;
pictureSource = navigator.camera.PictureSourceType;
destinationType = navigator.camera.DestinationType;
navigator.camera.getPicture(obj_imageCapture.onPhotoDataSuccess1, obj_imageCapture.onFail, {quality: 50, destinationType: destinationType.FILE_URI , saveToPhotoAlbum: true });
},
onPhotoDataSuccess1:function(imageData){
obj_imageCapture.createFileEntry(imageData);
},
createFileEntry:function(imageURI) {
window.resolveLocalFileSystemURI(imageURI, obj_imageCapture.copyPhoto, obj_imageCapture.onFFail);
},
copyPhoto:function(fileEntry) {
try
{
var ext = fileEntry.fullPath.substr(fileEntry.fullPath.lastIndexOf('.'));
var imageN = "";
if(FileName.indexOf('.') > 0)
{
imageN = FileName.substr(0,FileName.lastIndexOf('.')) + ext;
}
else
{
imageN = FileName + ext;
}
window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, function(fileSys) {
fileSys.root.getDirectory(FileFolder, {create: true, exclusive: false}, function(dir) {
fileEntry.copyTo(dir, imageN, obj_imageCapture.onCopySuccess, obj_imageCapture.onFFail);
}, obj_imageCapture.onFFail);
}, obj_imageCapture.onFFail);
}
catch(ex)
{
alert(ex.message);
}
},
onCopySuccess:function(entry) {
var smallimage = document.getElementById("myimage");
smallimage.style.display = "block";
smallimage.src = entry.fullPath + "?rand=" + Math.random();
},
onFFail:function(message)
{
alert("Error in photo : " + message.message);
}
};

Phonegap FileTransfer appears to do nothing in android

I'm having problems with the Phonegap FileTransfer API. Currently I'm trying to run the example code below:
saveFile: function (filepath,location, filetype) {
console.log("FUNCTION BEING CALLED");
var self = this;
//filepath is path to the internets file
//location is where on the device the file will be stored
var fileTransfer = new FileTransfer();
fileTransfer.download(filepath,self.rootPath + location + '.' + filetype,
function (entry) {
console.log('############# DOWNLOAD WORKS ##############');
console.log("download complete: " + entry.fullPath);
},
function (error) {
console.log('############# DOWNLOAD FAILS ##############');
console.log("download error source " + error.source);
console.log("download error target " + error.target);
console.log("upload error code" + error.code);
}
)
}
Currently, nothing at all appears to be happening. No errors are flagged, and the callbacks don't appear to be firing. All I get is the initial console.log of "FUNCTION BEING CALLED".
I've double checked, and can confirm that I'm including the cordova js file, (cordova-2.4.0.js).
If it matters, I've tried this on the Android Emulator, a HTC One X and a Samsung Galaxy S3, all with the same results.
Does anyone know what could be causing this?
Edit: I also felt I should mention that it's all running in an Angular JS app as well.

this is how i am doing it in my project
document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady() {
window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, gotFS, fail);
}
function gotFS(fileSystem) {
window.fileSystem = fileSystem;
//create directory test_app
fileSystem.root.getDirectory("test_app", {
create : true,
exclusive : false
}, dirWallpaper, fail);
function fail(evt) {
}
function dirWallpaper(entry) {
//save the directory path
window.testDir = entry;
}
//now download file to that location
saveFile: function (filepath,location, filetype) {
console.log("FUNCTION BEING CALLED");
var self = this;
//filepath is path to the internets file
//location is where on the device the file will be stored
var fileTransfer = new FileTransfer();
var path = window.testDir.fullPath + "/test_pdf."+ filetype;
fileTransfer.download(filepath,path,
function (entry) {
console.log('############# DOWNLOAD WORKS ##############');
console.log("download complete: " + entry.fullPath);
},
function (error) {
console.log('############# DOWNLOAD FAILS ##############');
console.log("download error source " + error.source);
console.log("download error target " + error.target);
console.log("upload error code" + error.code);
}
)
}
try like this and let me know.

Downloading pdf file in SD card using Phone Gap in android

I want to download pdf file in my android phone using phone gap.can any one help me to download it? i have used https://github.com/phonegap/phonegap-plugins/tree/master/Android/Downloader plugin but it is not working.If anybody have any other downloading method then please let me know..
Thanks in advance..

You can use the phonegap file api to download the files you want from server. Check docs for more detail - FileTransfer API
Here is an example code to download and save a pdf file in your sdcard.
window.appRootDirName = "download_test";
document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady() {
console.log("device is ready");
window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, gotFS, fail);
}
function fail() {
console.log("failed to get filesystem");
}
function gotFS(fileSystem) {
console.log("filesystem got");
window.fileSystem = fileSystem;
fileSystem.root.getDirectory(window.appRootDirName, {
create : true,
exclusive : false
}, dirReady, fail);
}
function dirReady(entry) {
window.appRootDir = entry;
console.log("application dir is ready");
}
downloadFile = function(){
var fileTransfer = new FileTransfer();
var url = "http://www.irs.gov/pub/irs-pdf/fw4.pdf";
var filePath = window.appRootDir.fullPath + "/test.pdf";
fileTransfer.download(
url,
filePath,
function(entry) {
alert("download complete: " + entry.fullPath);
},
function(error) {
alert("download error" + error.source);
}
);
}

Download files and store them locally with Phonegap/jQuery Mobile Android and iOS Apps

I wrote an jQuery Mobile app and packaged it with Phonegap to iOS and Android apps.
At this point I am using locally stored json files to read data.
I would like to update these json files from time to time by downloading newer json files from a server.
How can I get the json from the server and store the json files to the local file system of Android and iOS?
Cheers
Johe

Use FileTransfer.download, here is an example:
function downloadFile(){
window.requestFileSystem(LocalFileSystem.PERSISTENT, 0,
function onFileSystemSuccess(fileSystem) {
fileSystem.root.getFile(
"dummy.html", {create: true, exclusive: false},
function gotFileEntry(fileEntry) {
var sPath = fileEntry.fullPath.replace("dummy.html","");
var fileTransfer = new FileTransfer();
fileEntry.remove();
fileTransfer.download(
"http://www.w3.org/2011/web-apps-ws/papers/Nitobi.pdf",
sPath + "theFile.pdf",
function(theFile) {
console.log("download complete: " + theFile.toURI());
showLink(theFile.toURI());
},
function(error) {
console.log("download error source " + error.source);
console.log("download error target " + error.target);
console.log("upload error code: " + error.code);
}
);
}, fail);
}, fail);
};
}

This is how I solved it. First set the file paths, wich are different for Android and iOS
var file_path;
function setFilePath() {
if(detectAndroid()) {
file_path = "file:///android_asset/www/res/db/";
//4 Android
} else {
file_path = "res//db//";
//4 apache//iOS/desktop
}
}
Then I load my JSON files, wich are prepackaged with the app, into the local browser storage. Like this:
localStorage["my_json_data"] = loadJSON(file_path + "my_json_data.json");
function loadJSON(url) {
return jQuery.ajax({
url : url,
async : false,
dataType : 'json'
}).responseText;
}
If I wanna update my data. I get the new JSON Data from the server and push it into the local storage. If the server is on a different domain, which is the case most of the time, you have to make a JSONP call (check jQuery's docs on JSONP).
I did it kinda like this:
$.getJSON(my_host + 'json.php?function=' + my_json_function + '&callback=?', function (json_data) {
//write to local storage
localStorage["my_json_data"] = JSON.stringify(json_data);
});

You can do this in one line of code:
new FileManager().download_file('http://url','target_path',Log('downloaded success'));
target_path: can include directory (example: dira/dirb/file.html) and the directories will be created recursively.
You can find the library to do this here:
https://github.com/torrmal/cordova-simplefilemanagement

My suggestion would be to look into PhoneGap's File API. I haven't used it myself, but it should do what you're after.

Updated Answer for new Cordova
function downloadFile(url, filename, callback, callback_error) {
var fileTransfer = new FileTransfer();
fileTransfer.download(url,
cordova.file.dataDirectory + "cache/" + filename,
function (theFile) {
console.log("download complete: " + theFile.toURL());
if (callback)
callback();
},
function (error) {
console.log("download error source " + error.source);
console.log("download error target " + error.target);
console.log("upload error code: " + error.code);
if (callback_error)
callback_error();
}
);
}

For downloading and displaying a file, follow the sample code.
Include the given code just above the </head> tag in your index.html
< 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(
"dummy.html", {
create: true,
exclusive: false
},
function gotFileEntry(fileEntry) {
var sPath = fileEntry.fullPath.replace("dummy.html", "");
var fileTransfer = new FileTransfer();
fileEntry.remove();
fileTransfer.download(
"http://www.w3.org/2011/web-apps-ws/papers/Nitobi.pdf",
sPath + "theFile.pdf",
function(theFile) {
console.log("download complete: " + theFile.toURI());
showLink(theFile.toURI());
},
function(error) {
console.log("download error source " + error.source);
console.log("download error target " + error.target);
console.log("upload error code: " + error.code);
}
);
},
fail);
},
fail);
}
function showLink(url) {
alert(url);
var divEl = document.getElementById("deviceready");
var aElem = document.createElement("a");
aElem.setAttribute("target", "_blank");
aElem.setAttribute("href", url);
aElem.appendChild(document.createTextNode("Ready! Click To Open."))
divEl.appendChild(aElem);
}
function fail(evt) {
console.log(evt.target.error.code);
}
</script>
