StageWebview drawViewPortToBitmapData [PROBLEM]

When I try to capture the webview as a bitmap for some reason it is adding white space to the right of the bitmap. I think its putting space where the scrollbar is and not actually taking a picture of the scrollbar.
Does anyone know of a way around this ?

Since the area the scrollbar covers is considered part of the window, that will be included.

DrawViewPortToBitmapData issue on AIR 13.0.0.42

fixed on AIR 3.8 for IOS
https://bugbase.adobe.com/index.cfm?event=bug&id=3161013
Adobe AIR 3.8 relase notes, notable bug fixes:
StageWebView.drawViewPortToBitmapData draws incorrect bitmap on retina devices(3558603)
But this is still an issue on AIR 13.0.0.42 at Galaxy S3 (Android 4.3)
How to solve this problem?
There is an example test file (.fla) at zip: Link
here is the code:
import flash.display.Bitmap;
import flash.display.BitmapData;
import flash.events.MouseEvent
import flash.geom.Rectangle;
import flash.media.StageWebView;
var webView:StageWebView = new StageWebView();
webView.viewPort = new Rectangle(0,0,stage.stageWidth,stage.stageHeight-100);
webView.stage = this.stage;
webView.loadURL("http://labs.adobe.com/");
var webViewBitmap:Bitmap;
addBitmap.addEventListener(MouseEvent.CLICK, addBitmapClickHandler);
removeBitmap.addEventListener(MouseEvent.CLICK, removeBitmapClickHandler);
function addBitmapClickHandler(event:MouseEvent):void
          var rect:Rectangle = webView.viewPort;
          var bitmapData:BitmapData = new BitmapData(rect.width,rect.height,true,0xff0000);
          webView.drawViewPortToBitmapData(bitmapData);
          webViewBitmap = new Bitmap(bitmapData);
          webView.stage = null;
          addChild(webViewBitmap);
function removeBitmapClickHandler(event:MouseEvent):void
          if (contains(webViewBitmap))
                    removeChild(webViewBitmap);
          webView.stage = this.stage;

Thanks for reporting the issue, could you please try putting in “NO_SCALE” in your code as following?
stage.scaleMode = StageScaleMode.NO_SCALE;

Open hyperlinks in html text using StageWebView instead of external browser

My iPad app downloads xml data from a server and displays it as html text. The text may contain hyperlinks and currently these are correctly displayed as links in my app. However when I click on the link, it opens the link in an external browser.
Any idea how I could instead open the links using StageWebView - I know how to open a link using StageWebView - the problem is intercepting whatever causes it to open in the external browser and instead use StageWebView.
Thanks in advance

Hi, John, welcome to Apple's user-to-user discussion forums.
Does anyone here know of a way to open new windows without using command click in a tab?
If you want links on a web page to open in a new tab, you need to command-click on them. This will work both for links set up to open in the same window and those set up to open in a new window. There is no setting in Preferences to make links on a web page automatically open in a new tab.
There is a preference setting to open links from other programs, such as Mail, in a new tab. In Safari's Preferences, click on the General icon. Towards the bottom where it says "Open links from applications", check "in a new tab in the current window".

Problem with Android 4 StageWebView cutting off/covering up buttons on same View

So I'm trying to pull off something similar to the example here: http://cookbooks.adobe.com/post_Create_a_basic_web_browser_with_StageWebView-18850.html. Basically, a native browser view with a few Flex controls over top. Problem is, I've been running into a lot of display problems on Android 4 devices specifically. As far as I can tell, the StageWebView seems to be preventing the button overhead from being rendered in part or *at all* - as in, the button doesn't show up at all. It's just black.
See for yourselves. Here's a screenshot (the test page has a yellow background):
If I touch the screen or the web view, the button will (usually) abruptly show up above the page, where it's supposed to be:
Anyone else seen anything like this before? Any ideas what it could be?
Additional information for those who might want it:
- Project is being developed in Flash Builder 4.6 with the 4.6 SDK. Screenshots are from a Google Nexus 7 tablet (Android version 4.1.2, Adobe AIR version 3.4.0.254).
- the view in this case is an ActionScript class extending View with a skin. Here's the relevant code:
[SkinState("ready")]
[SkinState("loading")]
public class LogInWebView extends View
          [SkinPart(required="false")]
          public var previousButton:Button;
          private var browser:StageWebView;
          private var url:String;
          private var isFirstPageLoaded:Boolean;
          public function LogInWebView()
                    super();
                    isFirstPageLoaded = false;
          override public function set data(value:Object):void {
                    url = value.url;
                    invalidateProperties();
          // protected functions
          override protected function createChildren():void {
                    super.createChildren();
                    if (url) {
                              browser = new StageWebView();
                              browser.viewPort = new Rectangle(0, 0, stage.stageWidth, stage.stageHeight);
                              browser.addEventListener(Event.COMPLETE, onFirstPageLoaded, false, 0, true);
                              browser.loadURL(url);
          override protected function partAdded(partName:String, instance:Object):void {
                    super.partAdded(partName, instance);
                    if (instance === previousButton) {
                              previousButton.addEventListener(MouseEvent.CLICK, onPreviousButtonClick, false, 0, true);
                              if (browser) {
                                        browser.viewPort = new Rectangle(0, previousButton.height, stage.stageWidth, stage.stageHeight-previousButton.height);
          override protected function commitProperties():void {
                    if (isFirstPageLoaded && currentState != "ready" && browser) {
                              // display StageWebView now that it's loaded
                              skin.currentState = "ready";
                              browser.stage = this.stage;
                    } else if (currentState != "loading") {
                              skin.currentState = "loading";
                    super.commitProperties();
          // event listeners
          private function onFirstPageLoaded(event:Event):void
                    browser.removeEventListener(Event.COMPLETE, onFirstPageLoaded);
                    isFirstPageLoaded = true;
                    invalidateProperties();
- note: the button ONLY appears in state "ready" - it's not in state "loading."
Your thoughts?

Hi,
Not sure what your specific problem is, but I have encountered no problems at all by going a stage further with my implementation - it is based on http://soenkerohde.com/?s=stagewebview but I extended it to update on dimension changes of the container.
EG:
[code]
override protected function updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void {
super.updateDisplayList(unscaledWidth,unscaledHeight);
updateBrowser();
protected function updateBrowser(event:ResizeEvent=null):void {
if(myStage && stageWebView) {
var offsets:Point = new Point();
offsets = this.localToGlobal(offsets);
stageWebView.viewPort = new Rectangle(offsets.x, offsets.y, unscaledWidth, unscaledHeight);
[/code]
Seems to work for me, anyway. Hope it does for you too.

StageWebView x offset problem

I'm using StageWebView to load SWF files or HTML pages with SWF content on my Adobe Air 3.8 app for Android and I have a problem when I set the X offset in the viewport. The SWF gets cut off on the right side.
See this screenshot:
The viewport covers the area enclosed in the rectangle with a grey border but a portion of the rhino gets cut off. If I set the X offset to 0, the webview instance shows the SWF properly but the higher the X offset the wider the portion that gets cut off.
I need to add this happens only on Android running ICS (4.0.4). On devices running Jelly Bean, such problem does not happen.
One more thing: the black "patch" that covers the rhino part is the background color of the swf. I tested this problem with different SWFs and the strip that shows up on the right side is always of the same color as the remote SWF's background.
I need to show SWF content centered on the stage and this offset bug is a killer.
Does anybody know of a fix for a problem like this?
My code:
function loadFlashWebView():void {
    //load Flash webview for testing plugin
    webView = new StageWebView();
    webView.stage = this.stage;
    webView.loadURL(flashTestURL);
    webView.addEventListener(Event.COMPLETE, onLoadFlashViewComplete);
function onLoadFlashViewComplete(evt:Event):void {
    //load view complete handler
    trace("Web view finished loading. Error: " + webview_error);
    webView.viewPort = new Rectangle(67, 80, stage.stageWidth, stage.stageHeight); //the swf gets cut off in ICS
var flashTestURL:String = "http://mywebsite.com";
var webView:StageWebView;

Hi Laurent,
Which DAQmx driver version are you using?
It seems that the behavior you have was an unexpected one:
Error -200478 occurs when using DAQmx Perform Bridge Offset Nulling Calibration with AI.Temp.TC and ...
Neverthless, it was corrected in DAQmx 9.6 (see CAR 345144):

Embebed video problem in stageWebView

Hi,
I have a AIR for Android application with a stageWebView at all screen. And i must to charge a web page with one video embebed at stageWebView.
When i run my application at 2.2 Android device, i can see and listen the video, but if i use a 3.0 Android device, I can only listen the video.
If I try to charge the same web page at native navigator of 3.0 Android Device, the embebed video is playing correct, the video can listen and see.

StageWebView - How to prevent stretching of the bitmap obtained through drawViewPortToBitmapData?

I am trying to show the page displayed using StageWebView as a bitmap. As per the documentation we need to use DrawViewPortToBitMapData. While displaying the bitmap in a UIComponent, the image is getting stretched. How can I prevent that?
     bitmapData = new BitmapData(webView.viewPort.width, webView.viewPort.height, false,
     0x000000 );
     webView.drawViewPortToBitmapData(bitmapData);
     webViewBmp = new Bitmap(bitmapData);
     webView.stage = null;
   uiComponent = new UIComponent;
   uiComponent.width=webView.viewPort.width;
   uiComponent.height=webView.viewPort.height;
   uiComponent.addChild(webViewBmp);

If you do not want to programm anything you can just use the plugin part of the itexttoolbox. Tools->Various->IdentifyColorPages.
For java webstart installation go to
http://itext.ugent.be/library/itext.jnlp
It uses the first approach you described.

Problems with StageWebView on Android

Hello!
As I need to communicate with html content, was decided to use "javascript:" to call some methods in html content and catch onLocationChanging for call actionscript methods.
In my html page i use
document.location.replace('http://abobe.com/?param_name=param_value');
to change location, but onLocationChanging not launched.
How to fix this problem?

Hello,
Thanks for bringing this issue to our attention. We have this logged internally as bug #2790636 and it's currently being investigated. One possible workaround would be to use window.location="HOST#param=value" instead of document.location.replace('http://abobe.com/?param_name=param_value');
Hope this helps,
Chris

Calling javascript function with StageWebView problems

I have a test html page I made to R&D some functionality, in my view I have a stageWebView and am calling a local html file from inside the app like this:
stageWebView.loadURL(new File(new File('app:/assets/html/reports.html?stuff=1234').nativePath).url);
I then try and call a javascript function called tester() from the html page like this: stageWebView.loadURL("javascript:tester()");
And the only thing I see in the debug console is:
ReferenceError: Can't find variable: tester
From what I have found online this is the way that this should be done. Does anyone have any ideas? I am not running this on a device yet, just in the FlashBuilder emulator.
Thanks for any pointers.

Are you able to load the local html file? I have been trying to load a local file, test.html, using the web view have have not been able to get it to load at all. It always gives me a blank page using file: or app:
If you have gotten it to work could post a snippet for me to check out?
Thanks,

Try using viewActivate instead of activate

Print complete document from stagewebview

I have a air application that shows in a stagewebview a facebook app.
In that facebook app you have to fill in a form.
Under the form there is a print button (that won't work)
So I wrote my own print button.
But the problem is that I have to convert the viewport of the stagewebview to a bitmap
and then print the bitmap to pdf or my printer.
But he always just take the part that is shown on my stage.
But I have to print the whole document that is in the stagewebview...
Can anybody help me?
Here is my code to convert to bitmap and the print...
var bitmapData:BitmapData = new BitmapData(iBreedte,iHoogte);
webView.location;
webView.drawViewPortToBitmapData(bitmapData);
var webViewBitmap:Bitmap = new Bitmap(bitmapData);
var myPrintJob:PrintJob = new PrintJob();
var options:PrintJobOptions = new PrintJobOptions();
options.printAsBitmap = true;
myPrintJob.start();
var s:Sprite = new Sprite();
s.height = iHoogte;
s.width = iBreedte;
s.addChild(webViewBitmap);
s.scaleX = .40;
s.scaleY = .40;
myPrintJob.addPage(s, null, options);
myPrintJob.send();

PDL -- thank you for your reply.
What you gave me did spawn the print dialog allowing me to select a printer. However, when the document printed, the number of pages in the document was correct but the pages were empty except for the page x of y along the top and the name of the document along the bottom. Have you seen this before and do you know how to correct? Also, how do you suppress the info across the top and bottom of the report from printing?
Thanks

Sudden error I can't find and StageWebView (AIR for iOS)

Hey all,
In my app I allow a user to download files from a list and then typically use StageWebViews to display them (videos mostly). Recently my app started to misbehave.
I'm using Flash Builder 4.6 with AIR 3.2 on Win7 Pro 64.
I test on-device. I choose fast export (quick packaging) and debug right from Flash Builder so I can see traces/errors/etc from the iPad.
After downloading a ~40MB MP4, I save it to the applicationStorageDirectory (and mark it 'do not back up'). I then wait 3 seconds just to be sure the write has a few seconds to complete. Then I black out the screen with a black sprite, stick a close button on the screen and load the video into a new StageWebView.
The problem is the first time these larger 40MB videos are saved and attempted, TONS of code isn't firing off or affecting the display. The video plays just fine, centered on the screen. However all the code to remove tons of things from memory during video playback which has tons of trace statements sprinkled in is simply not affecting the iPads display. This ONLY happens on iPad1 (OS 5.1). iPad2 and iPad3 work just fine.
I presumed I was being too aggressive with the iPad1 and added more and more time between downloading, saving and setting the bit on the file so the iPad1 wasn't innundated with doing to much at once. I can add 25 minutes worth of setTimeout between playing this video for the first time and it will fail every time though. So it's not being innundated.
If the video is already downloaded and a user selects it, it works perfectly fine. All views/classes are disposing properly to free up as much ram as possible for the video playback.
Now, I'm getting this error randomly:
Error #2044: Unhandled ErrorEvent:. text=Plug-in handled load
I can't find where this is coming from. Has anyone seen this before? I don't know if it has anything to do with what I'm seeing fail here. I doubt it because I get it a very short time (few seconds) after the video starts playing back. I only get this video the first time a file is downloaded and played but then never again.
I have an UncaughtErrorEvent that isn't even catching this. Everything to do with the class that displays the video has try {} catch() {} blocks over every line of code. So doesn't the small file downloader class. Nothing is throwing an ErrorEvent.
Is there any easy way to find where this error is being generated? Something I might not know about the Flash Builder Debugger? Other errors show up and tell me where they occured, but this brand new error does not cause the app to fail and the debugger doesn't even flinch at it.
On the first part, has anyone recently seen their apps exhibit something like this? I have a list of files that I destroy before I show the video and it continues to exist even though I literally trace() all over the code that should destroy it and I see the traces. Everything is nulled. Objects no longer exist. The background isn't visible that I'm tracing as I build and it exists on the display list. It's very odd.
It'd just like suddenly StageWebView has an issue loading a freshly downloaded and saved file. It nukes the display list, nothing I do to it matters. But if the file already exists it all works fine.

Yes I use ie.jampot.nativeExtensions.MobileBackup. Worked perfectly fine before and continues to return a true Boolean value for success and Apple has never rejected the app. They initially did because I did not set the backup bit. I presume that means it's working just fine.
This app crashes after that code happens, during trying to load the content into a SWV. But hey, why not, I'll disable that and we'll see what happens. I'll report back. I get no errors at all when the app crashes (when I fast build for debugging and test on device). No errors at all. It just crashes. That's.. not good.
edit:
Nope sorry, didn't change a thing. The second time I use URLLoader after properly disposing of it each time it fails on any large files and the app crashes with no info back to Flash Builder. Even with MobileBackup disabled completely. Sucks.. Flash Builder profiler is showing me the reference counts on objects and I can see I'm cleanly disposing of everything properly.Something won't leave memory even though all reference counts are 0. This does NOT happen on iPad2 or iPad3, just iPad1 past OS 5.1. Ugh...
re-edit:
After profiling like crazy, tracing like crazy, crossing all my T's and dotting my....... lowercase j's...... I can only conclude there is now an intolerance for MP4s being played in a StageWebView of a certain filesize. YMMV but just making a quick demo app, downloading a 44MB MP4 and playing it works fine the first time. I then dispose of everything and verify it in profiler. I even run garbage collection manually on the profiler and it still curiously has a lot more memory in use than what it had at app launch. All instance (reference) counts are 0. Curiously memory is still pretty close to the same amount as the video I just played regardless that I disposed of the SWV instance completely. It's like the dispose isn't working. My method of dereffing the class level private variable is:
_swv.stage = null;
_swv.viewPort = null;
_swv.dispose();
_swv = null;
This doesn't seem to release the memory as fast as I'd like to see. Perhaps there's something lingering but that should properly dispose of that SWV instance.
Upon downloading the second video, the very second it's finished downloading (via binary mode URLLoader) the app crashes. It doesn't even fire off a complete event or error in any way, the app literally just quits. Perhaps the previous 40MB video is somehow still lingering and once I have that 44MB video in mem and try to load a different 40MB video it's 40+44=84MB ram trying to be allocated. I can't see why because as above, I'm disposing of the SWV. Reference counts of _swv is 0 after the first video is played and closed.
Really strange but be careful, something new is going on here. It used to work perfectly fine. It appears to be an issue since 5.1. Perhaps Apple caching the SWVs contents when it's not desirable to do so. I may have to go back and use StageVideo and draw up my own video controls. I only use SWV because both it comes with nice controls and a fullscreen built in that runs very smoothly. If it isn't broke, don't fix it.. Well.. it's broken.
I have verified that 20MB videos download and work fine. 40MB is giving me issues. Not sure where the line is here.

JavaScript button not working in StageWebView

Hi,
Does anybody have an idea why the Google+ "Invite your friends!" button is not working in a StageWebView window?
Button:
- https://developers.google.com/+/web/share/interactive#button_design
It's working within the Flash IDE but not on mobile.
I'm using Air 3.6 and Flash CS6.
Thanks for any input!

Make sure that you do not block [[JavaScript]]
Start Firefox in [[Safe Mode]] to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
See [[Troubleshooting extensions and themes]] and [[Troubleshooting plugins]]
If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
You can use "Disable all add-ons" on the ''Safe mode'' start window.
You have to close and restart Firefox after each change via "File > Exit" (on Mac: "Firefox > Quit")
