Upload an image with Phonegap: InvalidCastException - javascript

I am trying to upload a file to my server with Phonegap. I am currently stuck when an error that says:
InvalidCastException

Does anyone have an idea on how to make this work?
Thanks!

I'm thinking that you are malforming your options value. Do you need to pass JSON or an actual object?
Right now you are passing an array with text in it.
options = ["{\"filePath\":\"/CapturedImagesCache/PhotoChooser-51766419-c657-46db-a53d-f09bee300a89.jpg\",\"server\":\"http://my.server.co.nz/pages/fileupload\",\"fileKey\":\"file\",\"fileName\":\"PhotoChooser-51766419-c657-46db-a53d-f09bee300a89.jpg\",\"mimeType\":\"image/jpg\",\"params\":\"value1=test&value2=param\",\"chunkedMode\":false}"]
The error seems to involve deserialization issues.

Put your getImage, uploadImage, win, fail outside of $(document).ready 's inline function call.
Reference to win and fail are actually closure, and phone gap gets it as null when it is trying to access those methods directly. Phonegap is probably expecting a global function instead of hidden function inside a function.
PhoneGap's executes its code out side javascript context, what may work in true javascript fashion may not work correctly with phonegap.

I had a problem similar to yours. I solved this, changing mimeType parameter to 'text/plain'.
Do you use params to send? If it's false I think you need send empty params.

I had this problem before, try to prepare the image in the html first, and dont take it directly from the navigator, it may not saving the taken photo in it cash ;)
In my solution I suppose to have an image tage with id ='camera_image'
img id='camera_image'...
Then i set all the variables of the image in it and I upload it (as you will see in the following code).
here's the 2 functions i used:
function takephoto(){
navigator.camera.getPicture(
function(uri){
$('#camera_image').show();
var img = document.getElementById('camera_image');
img.style.visibility = "visible";
img.style.display = "block";
img.src = uri;
uploadPhoto(img);
alert("Success");
},
function(e) {
console.log("Error getting picture: " + e);
},
{
quality: 50,
destinationType: navigator.camera.DestinationType.FILE_URI
});
// Get URI of picture to upload
var img = document.getElementById('camera_image');
var imageURI = img.src;
if (!imageURI || (img.style.display == "none")) {
alert("Take picture or select picture from library first.");
return;
}
}
for choosing an existing photo:
function choosephoto(){
navigator.camera.getPicture(
function(uri) {
$('#camera_image').show();
var img = document.getElementById('camera_image');
img.style.visibility = "visible";
img.style.display = "block";
img.src = uri;
uploadPhoto(img);
},
function(e) {
console.log("Error getting picture: " + e);
},
{
quality: 50,
destinationType: navigator.camera.DestinationType.FILE_URI,
sourceType: navigator.camera.PictureSourceType.SAVEDPHOTOALBUM
});
// Get URI of picture to upload
var img = document.getElementById('camera_image');
var imageURI = img.src;
if (!imageURI || (img.style.display == "none")) {
alert("please select a pic first");
return;
}
}
in the upload function:
function uploadPhoto(img) {
imageURI = img.src ...
ps: sorry for the formatting of my code, it doesn't fix well.

Simple WebRTC webpage works well in Chrome and Safari, but not in Firefox

Background
I am building a local area network, WebRTC baby monitor with a raspberry pi camera module and USB microphone. The stream is synthesized with GStreamer and im using Janus Gateway to facilitate the WebRTC connection between a web browser and the Pi. The webpage and Javascript is a stripped down version of the streaming demo provided by Meetecho.
This is my first time using many of these technologies and am a bit in over my head with troubleshooting at the moment. I'm having trouble figuring out why the web page works in Chrome and Safari, but does not work in Firefox.
It works fine on Chrome and Safari:
In Firefox, the WebRTC connection seems to be successfully established and maintained (based on comparisons of the network traffic and console output between Chrome and Firefox), but the page seems to get caught up somewhere along the way:
Comparing the consoles
When comparing the console outputs of Chrome and Firefox, they are identical until this point where both consoles report Uncaught (in promise) DOMException: but for possibly different reasons?
Firefox says Uncaught (in promise) DOMException: The fetching process for the media resource was aborted by the user agent at the user's request.
Chrome says Uncaught (in promise) DOMException: The play() request was interrupted by a new load request.
Are these the same errors with different "Hints"? Or are they actually different errors due to some underlying difference between the browsers?
Immediately after this error, Firefox diverges from Chrome by reporting Remote track removed.
Im unsure if I am doing something silly in the JS to cause this or if there is some nuance about Firefox that I am missing.
Other details that might be helpful?
Below is part of the html (index.html) and javascript (janus_stream.js) for the page, the pastebin link contains the whole janus_stream.js.
// We make use of this 'server' variable to provide the address of the
// REST Janus API. By default, in this example we assume that Janus is
// co-located with the web server hosting the HTML pages but listening
// on a different port (8088, the default for HTTP in Janus), which is
// why we make use of the 'window.location.hostname' base address. Since
// Janus can also do HTTPS, and considering we don't really want to make
// use of HTTP for Janus if your demos are served on HTTPS, we also rely
// on the 'window.location.protocol' prefix to build the variable, in
// particular to also change the port used to contact Janus (8088 for
// HTTP and 8089 for HTTPS, if enabled).
// In case you place Janus behind an Apache frontend (as we did on the
// online demos at http://janus.conf.meetecho.com) you can just use a
// relative path for the variable, e.g.:
//
// var server = "/janus";
//
// which will take care of this on its own.
//
//
// If you want to use the WebSockets frontend to Janus, instead, you'll
// have to pass a different kind of address, e.g.:
//
// var server = "ws://" + window.location.hostname + ":8188";
//
// Of course this assumes that support for WebSockets has been built in
// when compiling the server. WebSockets support has not been tested
// as much as the REST API, so handle with care!
//
//
// If you have multiple options available, and want to let the library
// autodetect the best way to contact your server (or pool of servers),
// you can also pass an array of servers, e.g., to provide alternative
// means of access (e.g., try WebSockets first and, if that fails, fall
// back to plain HTTP) or just have failover servers:
//
// var server = [
// "ws://" + window.location.hostname + ":8188",
// "/janus"
// ];
//
// This will tell the library to try connecting to each of the servers
// in the presented order. The first working server will be used for
// the whole session.
//

The Questions
What am I doing wrong that prevents this from working in Firefox?
What can the diverging console outputs tell me about what I am doing wrong?
Do you have any suggestions on where to look / what to try to get this working in Firefox?
Any pointers or ideas are greatly appreciated! Please let me know if I can provide other information.
Thank you!
Update: Theory / Possible answer?
In an attempt to address the Uncaught (in promise) DOMException: The fetching process for the media resource was aborted by the user agent at the user's request. error, I changed video.play() to video.load(). This addressed the error, but the same Remote track removed and "No remote video" behavior persists.
In the meantime I may have discovered the more fundamental issue: The video stream from the Pi is H264, and from what I can tell, Firefox does not support this format? Perhaps this is the reason that I am having issues with firefox?
Can any of you confirm or deny this as the true issue?
The issue is related to H264 incompatibility, but after seeing this thread I realized i was a victim of the same issue.
I needed to update one line in my janus.plugin.streaming.jcfg file so that it looks like this:
RPI3: {
type = "rtp"
id = 1
description = "Raspberry Pi 3 Infrared Camera Module stream"
video = true
videoport = 5001
videopt = 96
videortpmap = "H264/90000"
videofmtp = "profile-level-id=42e01f;packetization-mode=1"
audio = true
audioport = 5002
audiopt = 111
audiortpmap = "opus/48000/2"
}
Previously I was using this "incomplete" line which was causing the issue:
...
videofmtp = "packetization-mode=1"
...
Apparently this enables the correct H264 "profile" that can work with Firefox's OpenH264 plugin. Now i am able to view the stream with both chrome and firefox!

Capture photo using navigator.camera or plain javascript

I want to take a photo by using device camera and it will be stored in the some type of thumbnail:
function onDeviceReady() {
pictureSource = navigator.camera.PictureSourceType;
destinationType = navigator.camera.DestinationType;
}
function onPhotoDataSuccessFront(imageData) {
var smallImageFront = document.getElementById('smallImageFront');
smallImageFront.style.display = 'block';
smallImageFront.src = "data:image/jpeg;base64," + imageData;
$('#btnFrontDiv').text('Retake Front');
}
As you can see I use navigator.camera which is avaliable in cordova/phonegap.
I want to capture photo by using cordova or plain javascript.
Thanks for any advice.
Try this one

<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
<title> Cmaer</title>
<script type="text/javascript" src="cordova.js" ></script>
<script type="text/javascript">
var pictureSource,destinationType;
document.addEventListener("deviceready",loaded,false);
function loaded() {
pictureSource=navigator.camera.PictureSourceType;
destinationType=navigator.camera.DestinationType;
}
function getPhoto(imageData) {
var smallImage = document.getElementById('smallImage');
smallImage.style.display = 'block';
smallImage.src = imageData;
}
function capturePhoto() {
navigator.camera.getPicture(getPhoto, onFail, { quality: 50 });
}
function onFail(message) {
alert('Failed because: ' + message);
}
</script>
</head>
<body>
<button onclick="capturePhoto();">Capture Photo</button> <br>
<img style="display:none;width:60px;height:60px;" id="smallImage" src="" />

You may use HTML5 which has brought a surge of access to device hardware.
See this Link Capturing Audio & Video in HTML5
Note :getUserMedia() has been supported since Chrome 21, Opera 18, and Firefox 17.
Please go through support browser list (for mobile phone also) before implementing this.

PhoneGap camera / photo to server upload, failing, with random dialog appearing

I am using phonegap 3.0.0
And in the process of attempting to upload a file to the server I am getting a couple things that are unexpected. First thing, a script error:
Error: SyntaxError: Unexpected token ':' line 624 of phonegap.js
(which I think is a lot older version of the js to begin with, as I could only find one on github)
Next thing I am getting which I don't see why/how this would prompt when I have never seen it on other apps.. is a little alert dialog:
When I click OK on the dialog thats when it attempts to carry out the rest of the script, and gives me the above error.
and the script I am using to upload is based almost to the letter the same as the one found on the phonegap site.. http://docs.phonegap.com/en/3.0.0/cordova_file_file.md.html#File
$('#select_photo').on('click', function()
{
$('#choice_of_file').click();
});
$('#upload_photo').on('click', function()
{
if(fmr.nullCheck($('#choice_of_file').val()) == true)
{
alert('Please Choose a Photo');
}
else
{
uploadPhoto($('#choice_of_file').val());
}
});
// Wait for device API libraries to load
//
(function(){document.addEventListener("deviceready", onDeviceReady, false);})();
// device APIs are available
//
function onDeviceReady() {
// Retrieve image file location from specified source
navigator.camera.getPicture(
uploadPhoto,
function(message) { alert('get picture failed'); },
{
quality : 50,
destinationType : navigator.camera.DestinationType.FILE_URI,
sourceType : navigator.camera.PictureSourceType.PHOTOLIBRARY
}
);
}
function uploadPhoto(imageURI) {
var options = new FileUploadOptions();
options.fileKey="file";
options.fileName=imageURI.substr(imageURI.lastIndexOf('/')+1);
options.mimeType="image/jpeg";
var params = {};
params.value1 = "test";
params.value2 = "param";
options.params = params;
var ft = new FileTransfer();
ft.upload(imageURI, encodeURI(domainURL+'upload/wizard/'+MembId), win, fail, options);
}
function win(r) {
console.log("Code = " + r.responseCode);
console.log("Response = " + r.response);
console.log("Sent = " + r.bytesSent);
}
function fail(error) {
alert("An error has occurred: Code = " + error.code);
console.log("upload error source " + error.source);
console.log("upload error target " + error.target);
}
the HTML for the form its reading..
<div style="position:absolute;top:-2000px;left:-2000px;background-color:#FFF;z-index:0" id="hide_file_input">
<form enctype="multipart/form-data" id="upload_profile_image" action="#none" method="post">
<input type="file" id="choice_of_file" name="choice_of_file">
</form>
</div>
Filekey should be the name attribute of file field
options.fileKey="choice_of_file";
Also it will be better if you can call deviceready before all functions are executed and put navigator.camera.getPicture in the onclick event of file field

upload images or videos to remote server using phonegap

I am doing project in android phonegap.Here I want to upload images and videos to remote server.
I used the following link.
http://zacvineyard.com/blog/2011/03/upload-a-file-to-a-remote-server-with-phonegap
I also change some options like options.chunkedMode = false ,android:debuggable="true" and
. But still it shows error code 3.I am using the cordova-2.0.0.js version.Can anyone suggest some answer.
My js code is
**
<script type="text/javascript" charset="utf-8">
// Wait for PhoneGap to load
document.addEventListener("deviceready", onDeviceReady, false);
// PhoneGap is ready
function onDeviceReady() {
// Do cool things here...
}
function getImage() {
// Retrieve image file location from specified source
navigator.camera.getPicture(uploadPhoto, function(message) {
alert('get picture failed');
},
{quality: 50,
destinationType: navigator.camera.DestinationType.FILE_URI,
sourceType: navigator.camera.PictureSourceType.PHOTOLIBRARY
}
);
}
function uploadPhoto(imageURI) {
var options = new FileUploadOptions();
options.fileKey="file";
options.fileName=imageURI.substr(imageURI.lastIndexOf('/')+1);
options.mimeType="image/jpeg";
var params = new Object();
params.value1 = "test";
params.value2 = "param";
options.params = params;
options.chunkedMode = false;
var ft = new FileTransfer();
ft.upload(imageURI, "url of ther server/upload.php", win, fail, options, true);
console.log("H");
}
function win(r) {
console.log("HIIIIIiiii");
console.log("Code = " + r.responseCode);
console.log("Response = " + r.response);
console.log("Sent = " + r.bytesSent);
alert(r.response);
}
function fail(error) {
alert("There is something");
alert("An error has occurred: Code = " + error.code);
}
</script>
**
and my php code is
<?php
print_r($_FILES);
$new_image_name = "namethisimage.jpg";
move_uploaded_file($_FILES["file"]["tmp_name"], "upload/".$new_image_name);
?>
Thanks.
Have you added the URL in question to your whitelist?
e.g. in config.xml do you have something like:
<access origin="www.myurl.com" subdomains="true" />
or
<access origin="*" />
which allows all URLs.
Error code 3 is a FileTransferError.CONNECTION_ERR by the way.

How do I upload an image using the Parse.com JavaScript SDK?

I'm using Parse.com to build a JavaScript app, and I need to upload photos. I have a form which allows users to select the image on their filesystem, but what do I do with it next? I can't find any documentation for this on the Parse site (not for the JavaScript SDK, anyway).
Here's a quick example on how to upload an image:
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<script type="text/javascript" src="http://www.parsecdn.com/js/parse-1.2.15.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
// ***************************************************
// NOTE: Replace the following your own keys
// ***************************************************
Parse.initialize("YOUR_APPLICATION_ID", "YOUR_CLIENT_ID");
function saveJobApp(objParseFile)
{
var jobApplication = new Parse.Object("JobApplication");
jobApplication.set("applicantName", "Joe Smith");
jobApplication.set("profileImg", objParseFile);
jobApplication.save(null,
{
success: function(gameScore) {
// Execute any logic that should take place after the object is saved.
var photo = gameScore.get("profileImg");
$("#profileImg")[0].src = photo.url();
},
error: function(gameScore, error) {
// Execute any logic that should take place if the save fails.
// error is a Parse.Error with an error code and description.
alert('Failed to create new object, with error code: ' + error.description);
}
});
}
$('#profilePhotoFileUpload').bind("change", function(e) {
var fileUploadControl = $("#profilePhotoFileUpload")[0];
var file = fileUploadControl.files[0];
var name = file.name; //This does *NOT* need to be a unique name
var parseFile = new Parse.File(name, file);
parseFile.save().then
(
function()
{
saveJobApp(parseFile);
},
function(error)
{
alert("error");
}
);
});
});
</script>
<body>
<input type="file" id="profilePhotoFileUpload">
<img id="profileImg"/>
</body>
