Still crashes, see below. I guess that is because I haven't installed
the framework files yet. It would be nice if this error message was
more user-friendly (like telling where to download the framework).

Where can one download a copy of the AOSP framework?

Agreed.

Understood, agreed. From what I read on the upstream website, there are
phone vendor frameworks (like for HTC) that are unlikely to be FLOSS.

Crash with Debian aapt:
