* <p>Threading: All accessor methods are synchronized on the same internal lock so it's safe to

*
* <p>Implementation Background:
*
* <ul>
* <li>The sdk manager has a set of "Package" classes that cover both local and remote SDK
* operations.
* <li>Goal was to split it in 2 cleanly separated parts: {@link LocalSdk} parses sdk on disk, and
* a separate class wraps the downloaded manifest (this is now handled within Studio only)
* <li>The local SDK should be a singleton accessible somewhere, so there will be one in ADT (via
* the Sdk instance), one in Studio, and one in the command line tool. <br>
* Right now there's a bit of mess with some classes creating a temp LocalSdkParser, some
* others using an SdkManager instance, and that needs to be sorted out.
* <li>As a transition, the SdkManager instance wraps a LocalSdk and uses this. Eventually the
* SdkManager.java class will go away (its name is totally misleading, for starters.)
* <li>The current LocalSdkParser stays as-is for compatibility purposes and the goal is also to
* totally remove it when the SdkManager class goes away.
* </ul>
*
* @version 2 of the {@code SdkManager} class, essentially.
