Re: [android-developers] Re: Market expanding to technically non-compliant devices?

I am sorry it is undocumented.  But it is there, and you can use it starting with 2.0 and later.

Except that what you describe is undocumented:

http://developer.android.com/guide/topics/manifest/uses-library-element.html

and, apparently, has been undocumented for over a year. While I have
been quietly pointing this undocumented feature out, based on your
assertions that we should be using it, please do not expect the bulk
of Android developers to be using features they are unaware of,
outside of the occasional [android-developers] post.

FWIW, this is reported as:
