        A simple list of platforms provided by the SDK Manager and some
        statistics on them, namely the market share percentage for that
        platform.
        This can be used by the SDK Manager or the ADT New Project Wizard
        to give users an idea of the relative install base of platforms.

        Scope, Caveat & Limitation:
        The "share percentage" corresponds to the Platform Versions table
        from the SDK Dashboard as seen at
        http://developer.android.com/resources/dashboard/platform-versions.html
        However the data is not automatically generated and there is NO
        freshness implied.  The values may or may not be up-to-date and it is
        most likely they will only get refreshed when there's a significant
        change that affects the usage of the SDK tools.

        =>  The data is distributed on an "AS IS" BASIS, WITHOUT WARRANTIES
        OR CONDITIONS OF ANY KIND, either express or implied.
