How to convert XML to Android Binary XML

figured this out using the Android packaging tool (aapt.exe)

aapt.exe package -f -m -J src -M AndroidManifest.xml -S res -A assets -0 "" -I android.jar -F MyApp.apk

This takes a plain xml manifest and packages it into binary XML and inserts it into the apk.

Unfortunately it requires that the resources and assets be present (if you refer to them within the manifest file itself). I also have to add any other data back into the apk file. Not ideal but it works at least
