Dear Robert,
you can use gc() only when you are testing your app not in a final release version.
So if you want to force GC you must work with FP 10 and UnloadAndStop method of Loader object and you can solve this problem

Wait, nvm, just found this: http://livedocs.adobe.com/flex/3/langref/flash/system/System.html#gc()

Re: Ashish. It’s not possible to invoke the garbage directly.

Thanks for your valuable code.
Could you tell me how can I invoke Garbage Collector in Flash Palyer. Since I am making an Explorer kind of thing in AIR and when i select a folder contents with thumbnail view i take almost 500 MB. any work around on that

Thanks in Advance
Ashish

I am having memory problems with the JPEGAsyncEncoder you mentioned. When loading many images, it consumes too much memory. Have you tried your class with JPEGAsyncEncoder ? or rather ,, can is there a way to use it with JPEGAsyncEncoder ?

Thank you in advance for your help

Yes I’m agree with you, I’ll create a sample that it will produce the initial problem.

Meanwhile I suggest to take a look at: http://blog.paranoidferret.com/index.php/2007/12/11/flex-tutorial-an-asynchronous-jpeg-encoder/

I downloaded your AIR application and code sample. The tests I did on my Mac did not show any significant difference in memory or process for either image loading. Maybe you need to create an example that shows the initial problem, loading multiple images into the application uses excessive memory.

I have a similar issue when I upload ByteArray data using FileStream in AIR. The entire bytes of a file are first read into AIR, then posted to a web site. Loading the entire bytes of the file increases the application memory significantly. I don’t think using ByteArray or BitMap saves any CPU memory or processing.
