how to open an .apk file

Question

hi i am a new developer, i created an app of my own. I created the .apk file and get it signed and aligned it. When i was running it on my device i thought of doing some changes in it, but i missed the original source code. Can i get back my source code using the aligned.apk file... I am using eclipse

The apk is just a zip file so you can unzip it. Your code will be in a classes.dex file in the dalvik format. There are some tools you can use to convert it back from dex2jar , and then decompile the class files using jad but your source code will most likely be imcomplete.
