You will be able to reference it outside of that function but not immediately, not until after the call back function happens.
Rob
Could you please explain to me how to do that?
local downloadedImage = nil
local function touchHandler( event )
if event.phase == “moved” then
if downloadedImage then
downloadedImage.x = event.x
– technically speaking, event.target would be better than downloadedImage
end
end
return true
end
local function networkListener( event )
…
downloadedImage = event.target
downloadedImage:addEventListener(“touch”, touchHandler)
…
end
display.loadRemoteImage(…)
This is a basic example of where you can reference an object outside of the download function.
Rob
Is that Still not possible today?
Yes, this is still true.

So what is the best way of displaying a video? A webview of youtube? I need users to be able to access movie trailers…
What is the best way to display a video? Well that’s tough to answer. Where is the video? What format is it in? Is it coming from a streaming service or do you have the entire video file?
Corona SDK’s built in video features are designed to work where you get a physical file. That is, I can play a video from a web server if I’m getting a .mp4 file. But if it’s a streaming service like YouTube, you don’t download a file you use a player to just stream data you will throw away when done. Corona SDK doesn’t have facilities to access data from that kind of service.
You can look at the code in our Business App Sample ( where we get a list of YouTube videos and then play the video in a webView.
Rob
Thanks a lot for your quick answer, I will look in to that!
I might just download the videos and host them myself…
One more problem: I do not understand why I get this error:“Attempt to index local ‘image’ (a nil value)”
local image = display.loadRemoteImage( “http://2.bp.blogspot.com/-LDaA7cP9MmA/Tddgg2e-HcI/AAAAAAAABoQ/xHH5Wau_V00/s1600/hello.png”, “GET”, networkListener, “helloCopy.png”, system.TemporaryDirectory, display.contentCenterX, display.contentCenterY)
image.x = -100 + image.x
Is there another way to move the image?
display.loadRemoteImage() doesn’t return a display object like the other API calls. Instead it will call your “networkListener” function when the image finishes downloading. At that point, the display object will be in “event.target” and you can move it inside the listener. At the point you call display.loadRemoteImage() it returns immediately and image doesn’t exist at that point.
Rob
Is there any way to create a normal display object from the loaded image? Sorry if this is a stupid question, I am learning to use corona…
local image
local function networkListener( event )
– you should of course test to make sure you really downloaded the image her, I’m not going to include that code.
image = event.target
image.x = -100 + image.x
end
display.loadRemoteImage( “http://2.bp.blogspot.com/-LDaA7cP9MmA/Tddgg2e-HcI/AAAAAAAABoQ/xHH5Wau_V00/s1600/hello.png”, “GET”, networkListener, “helloCopy.png”, system.TemporaryDirectory, display.contentCenterX, display.contentCenterY)
Yes but I still will not be able to acess the image out of the networkListenerfunction right?

Does any of you know a workaround to show youtube videos inside an App?
Hi there,
Havent used video in a while in an app and just wondering if anything has changed as regards playing video but it causes the user to leave the app because it plays on the devices native player. Is there any way around this? I want to play a small clip of video, the app will be on both iOs and Android and the video will be stored within the apps assets so it doesnt need to be pulled from a server or anything.
Whats the best solution?
Thanks
native.newVideo() allows you to set a width and height. Have you tried that? It may still suspend Android Apps though.

it’s a shame there isn’t an in-app video player, because switching to a native player, or viewing youtube means that the user has left your app, and that is bad for app store stats, am i right?
