(the shortcut runs your app from inside the Android system)
so your shortcut still works even if your source code is gone.
As Dave said your source code would normally be in Internal > Droidscript > your-project-name.
If it's not there then if you didn't specify obfuscate at build time it is *possible* to extract it from your APK.
Your APK should be in Internal > DroidScript > APKs.
Bit late for you now, but I would recommend everyone backing up their source code on a regular basis
(on the DS Home Page, long-touch on your project icon, touch Share SPK, touch Gmail, it will be attached to a draft email).
