Oops, sorry, you're quite right.  I had forgotten about the change in
emphasis when the project morphed from Moblin to Meego.

My understanding is that the Android NDK does provide a filtered set
of header files that contain the interfaces which are guaranteed to
remain stable over time.  So in that sense it borrows some of the
approach of the LSB, but of course there is no strong formal
specification or application portability scanner to test for the use
of interfaces beyond what is guaranteed to be stable.  (And of course,
the NDK doesn't use glibc for the C library.)

Yes, indeed; it's like saying, "LSB for embedded".  You have to
specify which embedded ecosystem you are talking about before such a
phrase makes sense.
