Error 301 only during APK build

Hello,

I have a perplexing problem. I have successfully built my application using the desktop profile as so:

adt -package -storetype pkcs12 -keystore zip_cert.p12 -storepass password -target bundle builds/windows config/Loader-app.xml data/Loader.swf data/VC.swf

However, when I switch to a mobile profile, like so:  

adt -package -storetype pkcs12 -keystore zip_cert.p12 -storepass password -target apk-emulator builds/android config/Loader-app.xml data/Loader.swf data/VC.swf

I'm given error 301: Application descriptor missing/cannot be opened. Obviously the file is okay, because it compiles with a desktop profile no problem. Am I missing something here? I'm using the latest version of the HARMAN sdk. Here is my Loader-app.xml for reference as well:
