如何从adobe Air创建的android apk中打开源代码（用flash编码）？

I am trying to generate the source code from apk (which is created by adobe air, which is actually coded in flash)but It generates with no java classes and no images in res folder. The app actually a game app which has a 50 images in it. Can any body suggest me that, how to get the converted flash code into java files and the resource through the apk. I would be obliged if any suggests. Thanks in advance.I am trying to generate the source code from ap
