Sadly it seems the situation hasn't evolved much :-(
The fonts are in the base.git repo under data/fonts. There are README and Notice files mentioning the Apache v2 license but this is not reflected in the font metadata. The font metadata actually contains contradictory information!
The Ahem test font does not have any license information attached to it.
No way of knowing who the upstream is. A FONTLOG should really be added.
And the Droid fonts themselves still refer to an unknown external EULA in the License Description field:
"License Description: This font software is the valuable property of Ascender Corporation and/or its suppliers and its use by you is covered under the terms of a license agreement.

Not the kind of choice that will build a collaborative font designer community around this to make the Android stack more multilingual...
I really doubt many font designers have heard about or read through the Apache v2 license. IMHO it's in the interest of Google and the Android community to pick a community-recognized font-specific license like the OFL to provide a better collaboration mechanism to extend the font and to take care of embedding/naming problems.
We need to get in touch with the Android folks again...
