Owen,
The reason it stops is because when you run SCons without any arguments it
defaults to building all targets under the current directory. Since
/Users/dev/.pic
is not under the current directory, scons will stop once it's built
everything that is under it, thus stopping after it builds the .apk.

I would sugguest using env.install() as your means to copy all files around
rather than Copy() and also shutil.
Also:
env_android.Command('#platform/android/java/libs/armeabi/libpic_android.so',
dir, Copy('platform/android/java/libs/armeabi/libpic_android.so', output))
Uses the source as the dir. This will not cause changes in the directory to
rerun this command.
Directory nodes have some special properties. This is a common SCons new
user mistake. You should use Glob(dir+"/*") and if there are files in
subdirectories, then you'll want to add those via Glob(dir+"*/*") and so on.
Hope this helps!
