Print a web page from a webview

I made an app that is just a webview showing a website, at a certain point in my website I have a button that prints a div via javascript, as it is it doesn't work, how can I make it possible?
my js code:
function printDiv(divName) {
var printContents = document.getElementById(divName).innerHTML;
var originalContents = document.body.innerHTML;
document.body.innerHTML = printContents;
window.print();
document.body.innerHTML = originalContents;
}

Play a youtube video inside an AIR app (AS3)

I'd like to know if it's possible to play a youtube video inside an AIR app using AS3 code.
It seems that youtube API is deprecated...
If anybody knows a way or a good tutorial.
Thx
----------------EDIT
I've tried this code :
var wt:uint;
var ht:uint ;
var webview:StageWebView ;
var rect:Rectangle;
var url:String;
url = "https://www.youtube.com/watch?v=hFupHx5G44s";
trace(url);
wt = this.stage.stageWidth;
ht = this.stage.stageHeight;
webview = new StageWebView();
rect = new Rectangle(0,300,wt,ht/2);
webview.stage = this.stage;
webview.viewPort = rect;
webview.loadURL(url);
But it's loading the all page of youtube (youtube video + the recommended videos..) with a scroller on the right.
I'd like to load only the video (not all the youtube page).

Edit :
I'd like to load only the video (not all the youtube page).
Use this link format :
url = "https://www.youtube.com/v/hFupHx5G44s";
for example, choose a format like below :
https://www.youtube.com/v/hFupHx5G44s - use the /v/ to get a SWF version
https://www.youtube.com/embed/hFupHx5G44s - use the /embed/ to get a HTML5 version
It's for an ANDROID AIR app.
You should have mentioned that detail in the question. You could try adding
Security.allowDomain("www.youtube.com");
Security.loadPolicyFile("https://www.youtube.com/crossdomain.xml");
//////////# End of Edit
Why not use stageWebView to load the embed (HTML5) player as web page?
The YouTube AS3 API being deprecated likely means you cannot create your own user interface or use features like search. You can re-create the search function easily though (load "search results" source into String and extract links by parsing the source code).
Anyways, I just tried this code below and it worked for an AIR Desktop App.Maybe you can use it as a starting point...
package
{
import flash.display.MovieClip;
import flash.display.BitmapData;
import flash.display.Bitmap;
import flash.display.Sprite;
import flash.display.Loader;
import flash.display.LoaderInfo;
import flash.net.URLRequest;
import flash.events.*;
import flash.system.*;
public class Youtube_AIR_code extends MovieClip
{
public var YT_Loader : Loader;
public var my_VIDEO_ID : String = "hFupHx5G44s"; //# the YouTube ID
public function Youtube_AIR_code ()
{
Security.loadPolicyFile("http://www.youtube.com/crossdomain.xml");
YT_Loader = new Loader();
YT_Loader.contentLoaderInfo.addEventListener(Event.COMPLETE, YT_Ready );
YT_Loader.load( new URLRequest("http://www.youtube.com/v/" + my_VIDEO_ID) );
}
function YT_Ready (e:Event) : void
{
trace("YouTube SWF :: [status] :: Loading Completed");
//addChild(YT_Loader);
//# Wait for Youtube Player to initialise
YT_Loader.content.addEventListener("onReady", on_YT_PlayerLoaded );
}
private function on_YT_PlayerLoaded (e:Event) : void
{
//# Check Original Width/Height - Scale it proportionally
trace( "YT_Loader content Width : " + YT_Loader.content.width );
trace( "YT_Loader content Height : " + YT_Loader.content.height );
//# Testing changed size and position
YT_Loader.width = 320; YT_Loader.height = 240;
YT_Loader.x = 30; YT_Loader.y = 100;
addChild(YT_Loader); //# can add to stage only
}
} //# End Public Class
} //# End Package

Re-loading Swf file from sdcard as3 Android

I am working on an android app where I wish to download swf files from an external server, save them to sdcard and load them later in the app. Downloading works fine and the swf is saved in the application directory. Here is my code that loads the swf from the sdcard :
var myloader:Loader = new Loader();
var myhomeButton:btnHome = new btnHome();
addChild(myloader);
var swfFilePath:File = File.applicationStorageDirectory.resolvePath("Android/data/myswffile.swf");
var inFileStream:FileStream = new FileStream();
inFileStream.open(swfFilePath, FileMode.READ);
var swfBytes:ByteArray = new ByteArray();
inFileStream.readBytes(swfBytes);
inFileStream.close();
var loaderContext:LoaderContext = new LoaderContext(false, ApplicationDomain.currentDomain);
loaderContext.allowCodeImport = true;
myloader.contentLoaderInfo.addEventListener(Event.COMPLETE, mycompleteHandler);
myloader.loadBytes(swfBytes, loaderContext);
function mycompleteHandler(evt:Event):void
{
myloader.contentLoaderInfo.removeEventListener(Event.COMPLETE, mycompleteHandler);
addChild(myhomeButton);
myhomeButton.height = _height * 0.08;
myhomeButton.width = myhomeButton.height;
myhomeButton.x = 10;
myhomeButton.y = 10;
myhomeButton.addEventListener(MouseEvent.CLICK, myexitfftn);
}
function myexitftn(evt:Event):void
{
myloader.unloadAndStop(true);
removeChild(myhomeButton);
gotoAndStop(1, "SomeOtherFrame");
}
the problem is when I click the exit button the swf unloads but when I reload it, it starts from the second frame of the loaded swf, the third time from the third frame and so on... Where am I going wrong or what is an alternative solution, please guide.

Try, addChild(myloader) in Complete handler and removeChild and null while exiting, so that loaded swf is completely removed from the memory like so:
function mycompleteHandler(evt:Event):void
{
myloader.contentLoaderInfo.removeEventListener(Event.COMPLETE, mycompleteHandler);
addChild(myloader);
//... Rest of code remains same
}
function myexitftn(evt:Event):void
{
myloader.unloadAndStop();
removeChild(myloader);
myloader = null;
removeChild(myhomeButton);
gotoAndStop(1, "SomeOtherFrame");
}

AS3 android camera roll crash and restart

Making an AS3 app for android that uses camera roll to load, select and then use an image.
The cameraroll browser works fine, but when the image is selected, the app crashes - almost every time - as it has worked on a handful of occasions (!?!) We assumed a memory issue and attempted to close all other windows / use smaller photos in the camera roll etc. and try different devices - but cannot recreate success consistently. Cannot find another ANE that works either
It fails at the point where the photo has been selected, and RESTARTS the app...
here's the relevant code, any help appreciated.
public function openGallery():void {
var cameraRoll:CameraRoll = new CameraRoll();
if(CameraRoll.supportsBrowseForImage) {
cameraRoll.addEventListener(MediaEvent.SELECT, imageSelected);
cameraRoll.addEventListener(flash.events.Event.CANCEL, browseCanceled);
cameraRoll.addEventListener(flash.events.ErrorEvent.ERROR, mediaError);
cameraRoll.browseForImage();
}
else { trace( "Image browsing is not supported on this device."); }
}
private function imageSelected(event:MediaEvent):void {
trace("Media selected...");
var imagePromise:MediaPromise = event.data as MediaPromise;
_dataSource = imagePromise.open();
if(imagePromise.isAsync) {
trace("Asynchronous media promise.");
var eventSource:IEventDispatcher = _dataSource as IEventDispatcher;
eventSource.addEventListener(flash.events.Event.COMPLETE, onMediaLoaded);
} else {
trace("Synchronous media promise.");
readMediaData();
}
}
private function onMediaLoaded(event:flash.events.Event):void{
trace("Media load complete");
_mediaBytes = new ByteArray();
_dataSource.readBytes(_mediaBytes);
_tempDir = File.createTempDirectory();
var now:Date = new Date();
var filename:String;
filename = now.fullYear + now.month + now.day+now.hours + now.minutes + now.seconds + ".JPG";
_file = _tempDir.resolvePath(filename);
//writing temporal file to display image
_stream = new FileStream();
_stream.open(_file,FileMode.WRITE);
_stream.writeBytes(_mediaBytes);
_stream.close();
if(_file.exists){
_imageLoader = new Loader();
_imageLoader.contentLoaderInfo.addEventListener(Event.COMPLETE,onMediaLoadedBitmapData);
_imageLoader.loadBytes(_mediaBytes);
}
}
private function onMediaLoadedBitmapData(event:Event):void{
trace("onMediaLoadedBitmapData");
var loaderInfo:LoaderInfo = LoaderInfo(event.target);
_bitmapData = new BitmapData(loaderInfo.width,loaderInfo.height,false,0xFFFFFF);
_bitmapData.draw(loaderInfo.loader);
addPictureToScreen();
}

I had a similar thing happen in Air for iOS but it was related to picking large images. I just checked the dimensions of the chosen image and then used a scalar matrix if they were past a certain point. Sounds like you've thought about this but maybe look further into that?

Improve this question
I know this question has been asked many times but it's still unclear for me if there is an existing and properly working library to natively display PDF documents.
I only want to view a PDF document which is stored inside my app. Opening a new Activity is ok for me, I don't need to display it inside an existing view. I've already built a piece of code to launch an activity intent for reading my local PDF file, but of course, if no PDF Viewer app is already installed on the device, then nothing happens.
I've heard about APV, VuDroid, droidreader, etc but it seems that they all are APKs, not libraries that can be used inside my app code.
So, is there any real Android library to achieve this?
Thanks in advance.

This one you can try it which works in offline mode
https://github.com/bitfield66/PdfViewerAndroid_Offline
which just accepts pdf path.

Firstly to view a pdf in android you have to convert the pdf into images then display them to the user. (i am going to use a webview)
So to do this we need this library. It is my edited version of this git.
After you have imported the library into your project you need to create your activity.
The XML:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<WebView
android:id="#+id/webView1"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</LinearLayout>

I like the MuPDF Adnroid lib since it written in C++/NDK and it has unique features like clickable images (I mean an URL linked to the image) - met no other lib with this feature and I was really need it.
You actually can open PDF using no lib at all: using WebView via google docs but I don't like this way due to IC is required all the time while using MuPDF I can DL pdf file and freely open it offline any time. Also WebView way is more "hard" for device meaning battery draining + lags + CPU heating and it uses more trafic (if compared to DL&show way).
