Adobe AIR Development

Hello,

I want to view an image form the applicationStorageDirectory but I get an URL not found error.

var imgLoad:Image = new Image();
imgLoad.setImage(File.applicationStorageDirectory.nativePath + "/test.png");
imgLoad.setSize(1024, 600);

The image test.png is present in that directory but I can't load it.

Does anyone have a solution?

How did you get that image in the storage directory?  Installed files are only in the applicationDirectory relative to the /src of your project.  If that image was saved there and the File "exists" method is returning true, it might be related to something else.

If the file does exist, you can use try this solution using QNX's Image Class ( thanks JRab )

jrab's example is for files relative to the project /src directory.  They're trying to load a file from the application storage directory.  I do this in one of my apps and it works fine as an AIR application, but I think there might be a problem on the PB.  I wll double check.

Yes, I too am having trouble loading an image from the app storage directory.  I dont have trouble access preference files from the same directory.  This might require a work around by loading the image into memory as a bitmap and then setting that to the image.

Thank you for the quick reactions 

The image is created by the application and I checked Its existence. 

The "Image" class in the piece of code is already the qnx.ui.display.Image class.

"The "Image" class in the piece of code is already the qnx.ui.display.Image class."

Yes it was...  :blush: I didn't notice the setImage(...  portion of your code.

hey Tjitte,

this was bugging me too but then saw the documentation closer and an assist from harry_dodgson. in the setImage method it requires a URL input not just an absolute path. so do this:

change:

imgLoad.setImage(File.applicationStorageDirectory.nativePath + "/test.png");

to this:

imgLoad.setImage("file://" + File.applicationStorageDirectory.nativePath + "/test.png");

and you should be golden. hope that helps! good luck!

Edit: from the documentation:

"... The image parameter can be of type String as a URL to an external image..."

Gotta love the differences between AIR and the simulator.  Worked for me.

Your solution was perfect J. Rab. Everything is working now.

Thank you all for your help!
