@jeffcliff @cnx It isn't - the offered images contain lots of proprietary libraries, including google spyware (like google play).

Even the wikipedia page admits that it's proprietary software.

google SDK's required to build Android are proprietary software, thus to get a free version of Android-AMD64, you would need to download a free SDK, remove all the proprietary libraries (difficult as they're often not marked as such) and spend 80 hours getting it to compile with such free SDK.
