All Over Software Jobs: Re: [flexcoders] blackberry playbook cameraUI, cameraRoll problems

BTW If you are getting errors loading in media from Blackberry Playbook make sure to enable the permission "access_shared". Otherwise you will get a Error 3003.

i use panels instead of titlewindows. it works for popups (check desktop version at www.sharedboard.net, and a tablet version on bberry or android)

by the way, the solution for the first letter: cameraroll is not supported in bberry, so it goes to the else {} part, where it needs permission to access shared media. thats it :)

Thanks for that. In my case I'm looking for something more comprehensive, I have an existing Air desktop app with much code that in principle was written in AS3 and Skins to be re-used but it references things that don't exist in Mobile Projects. For example TitleWindows (popups), Mobile projects complain that they don't have this component. So now we have to re-architect things a bit to figure out how to do what we want to do whilst we maximise code sharing.

its a simple mobile project.. i tick all mobile os-es (bberry, android, iphone).
there are some parts (like menu button) where i have an if (qnx||android) removeMenuBtn() like functions. (see below for code) (because on bberry, swipe_down is the menu, and android has a menu key)

the only trick there is a bug in the PlayBook swipe_down with the simulator, so i have to toggle the // in the beginning of this line, when releasing:
private function deviceIsPlaybook():void {
// QNXApplication.qnxApplication.addEventListener(QNXApplicationEvent.SWIPE_DOWN, swipeDown);//errort dob :S
hgroup.removeElement(menuBtn);
}

So this is how you check system:

if (flash.system.Capabilities.version.substr(0,3) == "IOS"){ //WIN, MAC, UNIX, AND
//iOS

trace("device recognised as iOS device")
} else if (flash.system.Capabilities.version.substr(0,3) == "QNX"){

//Blackberry
trace("device recognised as PlayBook")

try {
deviceIsPlaybook() //this must be a separate function, otherwise it won't catch the simulator error

} catch(error:Error) { }

} else if (flash.system.Capabilities.version.substr(0,3) == "AND"){
//Android

trace("device recognised as Android device")
hgroup.removeElement(menuBtn);

//listen for menu key elsewhere!
} else {

//Desktop
trace("device recognised as desktop")

}

May I ask what technique you are using for code sharing between platforms? Currently a hot topic in my opinion, I saw an interesting video from Adobe Max where some Adobe devs talked about it, apart from that there are no resources or recommendations out there.

Hi!
I'm developing Shared Board (sharedboard.net) for multiple platforms: iPad, Android, Playbook, and desktop.
I have 2 problems with PlayBook, what runs flawlessly on iPad: (I've included the working the working desktop solutions, those are the else parts)

First is when I want to add an Image to the visCompHand.toMove MC with the cameraRoll Browse for Image function: on iPad, desktop it works perfect, but on PlayBook, if I select a picture, it doesn't load it to the MC.

if(CameraRoll.supportsBrowseForImage){
cameraRollom=new CameraRoll();
cameraRollom.addEventListener(MediaEvent.SELECT, onMediaSelect);

cameraRollom.browseForImage()

function onMediaSelect(e:MediaEvent):void{
var promise:MediaPromise=e.data

loader.loadFilePromise(promise)
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, imageContentLoaderComplete);

FlexGlobals.topLevelApplication.homeView.addElement(visCompHand);
visCompHand.toMove.addChild(loader);

}
} else {
var imagesFilter:FileFilter = new FileFilter("Images", "*.jpg;*.gif;*.png;*.swf;");
var imageFile:File = new File();

imageFile.browseForOpen("Select an Image", [imagesFilter]);
imageFile.addEventListener(Event.SELECT, imageSelected2);

function imageSelected2(e:Event):void{

imageSelected(e.target as File);
}
}

Second is when I try to save the board MC as picture to cameraRoll. On iPad it works, on Playbook it fails:
if(CameraRoll.supportsAddBitmapData){
cameraRollom=new CameraRoll();
var imagesn:ImageSnapshot=ImageSnapshot.captureImage(FlexGlobals.topLevelApplication.homeView.board)
var loader : Loader = new Loader();

loader.contentLoaderInfo.addEventListener(Event.COMPLETE, getBitmapData);

loader.loadBytes(imagesn.data);

function getBitmapData(e:Event):void{

var content:*=loader.content;
var image:Bitmap = Bitmap(content);
/** get the bitmapdata **/

var bitmap:BitmapData = image.bitmapData
cameraRollom.addBitmapData(bitmap)
}
} else {
var image:ImageSnapshot = ImageSnapshot.captureImage(FlexGlobals.topLevelApplication.homeView.board, 300, new PNGEncoder());
var file:FileReference = new FileReference();
var date:Date=new Date();
var month:String=date.getMonth()+1+""

if (date.getMonth()<9) month="0"+month;
var day:String=date.getDate()+"";
if(date.getDate()) day="0"+day
file.save(image.data, "SharedBoard"+date.getFullYear()+month+day+".png");
}

I also have a bonus question:
I want to add picture as in 1st problem, but from the webcam/camera, and one that runs on neither platform:

if(CameraUI.isSupported){
cameraUIom=new CameraUI()

cameraUIom.addEventListener(MediaEvent.COMPLETE, onCameraComplete)
cameraUIom.launch(MediaType.IMAGE)

}

Thanks for any help!
