Kohana - API, Loging In, authorisation and accessing session

I'm trying to create android application using Kohana API (kohana 3.1) (with module kohana-restful-api).
And I have problem with making session stay at application (No cookies in apk). I have wrote this controller which I think is a problem:
class Controller_Restapi_Login extends Controller_Restapi_Default{
public function action_create(){
// Jeżeli przesłano dane z formularza
$post = $this->request->post();
if(!empty($post))
{
// zapisanie informacji do ciastka, użytkownik będzie zalgowany nawet po wyłączeniu i ponownym włączeniu przeglądarki
if( Auth::instance()->login($this->request->post('adm_login'), $this->request->post('adm_haslo')) )
{
// Logowanie zdarzenia
$objWiLog = ORM::factory('Orm_WiaLogi');
$objWiLog->log_akcjaID = 2;
$objWiLog->save();
$sessionID = Auth::instance()->get_user()->adm_id;
$wiadomosc = $sessionID;
$this->response->body(json_encode($wiadomosc));
}
else
{
try {
// Logowanie zdarzenia (nieudane logowanie)
$objWiLog = ORM::factory('Orm_WiaLogi');
$objWiLog->log_akcjaID = 4;
$objWiLog->log_adminID = ORM::factory('Orm_WiaAdministratorzy')->where('adm_login', '=', $this->request->post('adm_login'))->find()->adm_id;
$objWiLog->log_opis = 'Próba logowania przy użyciu loginu: '.$this->request->post('adm_login');
$objWiLog->save();
}
catch(ORM_Validation_Exception $e) {
//
}
catch(Database_Exception $e) {
// Nieprawidłowy login
}
$arrRespons = array(
'id'=> 1,
'type'=>'e',
'message' => 'Nieprawidłowy login lub hasło ',
'action'=>'gotoLogin',
);
$this->response->body(json_encode($arrRespons));
}
} else {
$this->response->body(json_encode('Błąd Logowania - Brak Loginu'));
}
}
}
Sorry for bad english, I hope someone understands.

how to use socket.io in native cocos2djs app

my project is normal in web browser, HTML5 version is work.
But after compile to apk by command 'cocos run -p android', socket.io is useless server side cannot receive any information.
I know something is improper, but I cannot find a concrete solution. Please help me.THANKS
server.js as follow:

console.log('Server on port 3000.');
var player = new Array();
var player_data = {
name: "",
kill: 0,
dead: 0
}
io.sockets.on('connection', function (socket){
console.log("come in");
socket.on('join_success', function (name){
console.log("name is"+name);
player_data.name=name;
player.push(player_data);
io.sockets.emit("updateAllPlayerData", player);
});
});
app.js as follow
var basicLayer = cc.Layer.extend({
ctor: function(){
this._super();
var size = cc.director.getWinSize();
var ball = new cc.Sprite(res.png1);
ball.x = 100;
ball.y = 100;
var ui = new GameUI;
sio_client= SocketIO.connect("http://localhost:3000");
sio_client.on("updateAllPlayerData", function(data){

white thumbnail for uploaded video in android app

I am making api's for my android app using Slim framework.But when i upload video to local server from my android app by calling api,it generates white thumbnail for video in my app.How can i get the thumbnail for the uploaded video.
My code for making api is:
$app->post('/do_upload', 'authentication', function () use ($app) {
verifyRequiredParams(array('albumId'));
global $user_id;
$response = array();
$file_path = "../uploads/$user_id/photo_gallery/thumbnails/";
if (!file_exists($file_path)) {
mkdir($file_path, 0777, true);
}
$thumbnail = $user_id . "/photo_gallery/thumbnails/";
$response = array();
if (isset($_FILES["files"])) {
$temp = explode(".", $_FILES['files']['name']);
$detectedType = $_FILES["files"]["name"];
$filetype = substr($detectedType, strpos($detectedType, ".") + 1);
$newfilename = 'shared_' . rand(1, 99999) . '.' . end($temp);
$file_path = $file_path . basename($newfilename);
$thumbnail = "$user_id/photo_gallery/thumbnails/" . $newfilename;
$filename = "$user_id/photo_gallery/thumbnails/" . $newfilename;
$mobile_thumbnail = "$user_id/photo_gallery/thumbnails/" . $newfilename;
if (move_uploaded_file($_FILES['files']['tmp_name'], $file_path)) {
}
$albumId = urldecode($app->request->post('albumId'));
$caption = urldecode($app->request->post('caption'));
$db = new DbHandler();
if (($filetype == "gif")
|| ($filetype == "png")
|| ($filetype == "jpeg")
|| ($filetype == "jpg")

$result = $db->SharedImage($albumId, $user_id, $caption, $filename, $thumbnail, $mobile_thumbnail, $type);
} else {
$type = "video";
$result = $db->SharedImage($albumId, $user_id, $caption, $filename, $thumbnail, $mobile_thumbnail, $type);
}
if ($result != "null") {
while ($res = $result->fetch_assoc()) {
$response = array();

Please tell me why the thumbnail of video uploded is white and how can i get the video cover.

Using ffmpeg ,My problem was solved.Here is the code exec('ffmpeg -y -i '.$file_path.' -vcodec mjpeg -ss 00:00:01 -vframes 1 -an -s 620x440 -f rawvideo '.$image.'',$thumb_stdout, $retval);
This created a thumbnail at path $image of size 620*440.

Chromecast Multi-language playready not detecting languages

I'm trying to play multi-language audio tracks on chromecast. It plays the video/audio files but it does not switch from English to Spanish. I can switch using the same file in a silverlight player. I've set my chromecast player language and my android phone language to be spanish. In the Google Cast SDK Developer console, I added spanish as an alternate track.
I've added my custom player using the code specified in the google guides, however the code in the guides does not appear to work from a straight copy and paste. Can someone direct me as to why protocol.getStreamCount() is 0? Is the timing of the call correct? Here's the entire player that I'm using, pay particular attention to window.changeLanguage = function()... and the changeLanguage call. Any help is extremely appreciated!

Chromecast Console:
Application is ready, starting system
Starting media application
we have protocol .ism/manifest
Starting Media Player Library
streamCount: 0
i: 1
currentLanguage: 0
EDIT
I went into console and post loading called the following command:
this.protocol.getStreamCount()
2
So this is clearly a timing issue. I need to call changeLanguage once the stream has fully loaded. I'm investigating when the appropriate time to call it is. I'd appreciate any help but I'll try to google this answer now that I'm positive it's a timing issue.

Answer is:
host.onManifestReady = function() {
changeLanguage();
};
This will provide the correct timing for when to pull the alternate audio tracks.

Why is the link element's onload attribute unreliable for android stock browsers?

var style1 = document.createElement("link");
style1.id = "rel";
style1.rel = "stylesheet";
style1.href = "http://www.mysite.com/css.css";
style1.onload = function(){document.body.innerHTML+="fffffff";};
document.getElementsByTagName("head")[0].appendChild(style1);
This code works in Chrome/Firefox, and yet stock browsers on my Froyo (2.3) and Jellybean (4.1) Android devices will print nothing. What's the problem? I'd like if I could execute some js onload of a link. Anything else would in my case amount to a hack. :/
The problem isn't innerHTML. Try it with alerts if you want (at your own peril).
Another answer mentions checking for this functionality by doing
var huh = 'onload' in document.createElement('link');
..but this is true in both stock browsers! wtf guys?

Android browser doesn't support "onload" / "onreadystatechange" events for element: http://pieisgood.org/test/script-link-events/
But it returns:
"onload" in link === true
So, my solution is to detect Android browser from userAgent and then wait for some special css rule in your stylesheet (e.g., reset for "body" margins).
If it's not Android browser and it supports "onload" event- we will use it:
var userAgent = navigator.userAgent,
iChromeBrowser = /CriOS|Chrome/.test(userAgent),
isAndroidBrowser = /Mozilla\/5.0/.test(userAgent) && /Android/.test(userAgent) && /AppleWebKit/.test(userAgent) && !iChromeBrowser;
addCssLink('PATH/NAME.css', function(){
console.log('css is loaded');
});
function addCssLink(href, onload) {
var css = document.createElement("link");
css.setAttribute("rel", "stylesheet");
css.setAttribute("type", "text/css");
css.setAttribute("href", href);
document.head.appendChild(css);
if (onload) {
if (isAndroidBrowser || !("onload" in css)) {
waitForCss({
success: onload
});
} else {
css.onload = onload;
}
}
}
// We will check for css reset for "body" element- if success-> than css is loaded
function waitForCss(params) {
var maxWaitTime = 1000,
stepTime = 50,
alreadyWaitedTime = 0;
function nextStep() {
var startTime = +new Date(),
endTime;
setTimeout(function () {
endTime = +new Date();
alreadyWaitedTime += (endTime - startTime);
if (alreadyWaitedTime >= maxWaitTime) {
params.fail && params.fail();
} else {
// check for style- if no- revoke timer
if (window.getComputedStyle(document.body).marginTop === '0px') {
params.success();
} else {
nextStep();
}
}
}, stepTime);
}
nextStep();
}
