At Last………..CriticismAt Last………..Criticism

Google announce it is open source but license says…….

3.2 You agree that Google or third parties own all legal right, title and interest in and to the SDK, including any Intellectual Property Rights that subsist in the SDK. "Intellectual Property Rights" means any and all rights under patent law, copyright law………………………………..

3.4 Use, reproduction and distribution of components of the SDK licensed under an open source software license are governed solely by the terms of that open source software license ………..

Google releasing code under Apache 2 licenses rather than GPL2………Why ?????

Android only reuses the Java language syntax, but does not provide the full-class libraries and APIs bundled with Java SE or ME
