I am trying to download an apk file on a button click using phonegap. Why does this code not work? Nothing happens when I click Download. Could someone point me in the right direction? Thanks.

fileTransfer.download(uri,filePath,

function(error) {
//failed

);
This worked for me
Your code works fine.
This seems stupid but have you tried to use alert() instead of console.log() in the callbacks?
If you are sure the callback code is not invoked try to run just the app created by the phonegap' create script and check that the device is ready before doing other tests.

I'm trying to use cordova-plugin-file-opener2 to load a pdf in Cordova. I can't seem to get it to work in the browser or on Android.
Here is my app.js file:
(function () {
document.querySelector('#file-button').addEventListener('click', openFile);
function openFile(){
console.log('opening file');
console.log(cordova.file.applicationDirectory);
var fileName = 'www/assets/pdf/foo.pdf';
var pathToFile = cordova.file.applicationDirectory + fileName;
window.resolveLocalFileSystemURL(pathToFile, function (entry) {
cordova.plugins.fileOpener2.open(
entry.toInternalURL(),
'application/pdf', {
error: function (e) {
alert.log('Error status: ' + e.status + ' - Error message: ' + e.message);
},
success: function () {
alert.log('file opened successfully');
}
}
);
}, function (e) {
alert('File Not Found');
});
}
}());
And here's the html:
<!DOCTYPE html>
<html>
<head>
<script src="cordova.js"></script>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0, user-scalable=no, minimum-scale=1.0, maximum-scale=1.0">
</head>
<body>
<p><button id="file-button" class="help-btn">Help</button></p>
<div class='header'><h1>Directory</h1></div>
<div class='search-view'>
<input class='search-key' type="search" placeholder="Enter name"/>
<ul class='list employee-list'></ul>
</div>
<script src="lib/jquery.js"></script>
<script src="js/services/memory/EmployeeService.js"></script>
<script src="js/app.js"></script>
</body>
</html>
When the 'file-button' is clicked, it triggers the openFile function.
This shows me the following in the console:
adding proxy for Device cordova.js:1010:9
adding proxy for File cordova.js:1010:9
opening file app.js:6:9
"http://localhost:8000/" app.js:7:9
And the alert message says 'File not found'.
App.js is located in www --> js
foo.pdf is located in www --> assets --> pdf
I'm totally new to the Parse API as well as server side js in general. I'm trying to write a simple function to register a new user when the click the submit button the corresponding form. I commented out all of the jquery pulling the data in the form and just have the function trying to register with a hard code username and password. I also took out my apps keys but they are correct in the original. Here's the showing the js links.

And here's the javascript file.
Parse.initialize("App Key",

$('#register').click(function(){
/* var registerFName = $('#registerFName').val();
var registerLName = $('#registerLName').val();
var registerUsername = $('#registerUsername').val();
var registerEmail = $('#registerEmail').val();
var resisterPassword = $('#registerPassword').val();*/
var user = new Parse.User();
user.set("username", "MyName");
user.set("password", "MyPassword");
/*user.set("email", registerEmail);
user.set("FName", registerFName);
user.set("LName", registerLName);*/
user.signUp(null, {
success: function(user) {
// Hooray! Let them use the app now.
console.log("User created");
},
error: function(user, error) {
// Show the error message somewhere and let the user try again.
alert("Error: " + error.code + " " + error.message);
}
});
});
Here's the console error:
parse-1.3.2.min.js:1 Uncaught RangeError: Maximum call stack size exceeded
Like I said, I'm pretty new to all of this but couldn't find a thread anywhere describing this exact issue with Parse. Any help would be appreciated.
According to the Parse documentation, signUp is a static method on Parse.User so it should be called a little differently. You also need to pass signUp the username and password.
It should be used as follows
Parse.User.signUp(username, password, {}, {
success: function (user) {
alert("Yay!");
},
error: function (user, error) {
alert("Error: " + error.code + " " + error.message);
}
});
Also the error you are getting is
Uncaught RangeError: Maximum call stack size exceeded
This error is thrown only when the, method calls itself infinitely, in such a case the stacks gets overloaded an throws this exception.
I am trying to establish a websocket connection between my signalR server and an android app, built using the phonegap CLI.
The javascript code runs on browsers on my PC but when I package it for android it fails to connect and gives the following error: Error during negotiation request

The asp.net code is hosted on azure.
I also tried to connect without the generated proxy(commented code) which again worked on chrome but not on the android emulator(4.4).
Could someone tell me what I am doing wrong?
Thanks
I am having the same problem as you.
Websocket is a feature within html5 and is not supported by all browsers
Chrome browser supports websockets but android 4.4 (jelly beans) In-browser doesn't.
This is why Android developed kitkat (which supports the websocket).
If you want to use websocket within android 4.2,4.4 (jelly beans), you have to use websocket cordova plugin like the one here
there are alot of others and I am just like you trying to find an answer
I'm working on mobile device (iOS). I develop a hybrid application using HTML/CSS/Javascript.

I can capture my voice with it and in theory upload it to
http://my.domain.com/upload.php
But I wonder how to adapt this code to upload file on my Dropbox . Is it possible to upload file to Dropbox as easy as that ?
As #sinaneker mentioned, you can do this server-side with PHP (or other languages).
But you can also do this directly from JavaScript using Dropbox's JavaScript library: https://github.com/dropbox/dropbox-js
I was working on a very simple page which just pulls and displays images from a table in parse.com. I do not have much experience with javascript which might be evident from the code below.
I need the images to show up in a chronological order. With the current code, it works fine most of the times but is a little buggy.
There are 2 main problems:
1) Sometimes, randomly, one particular new image might not come on the top and instead show up somewhere in between.
2) This page works on Firefox and Chrome but NOT on IE.
Is there a better way to implement this or is there something that I should change? Any help would be appreciated.

Internet Explorer blocks mixed content. Since Parse's JavaScript SDK requires SSL, you need to host your app using HTTPS as well in order to access it from IE.
Hey you made one mistake. it was not working for me. Then i found that it is url() not url.
The amendment is img.src = results[i].get("image").url();
