It would be also good to add @deprecated in the javadoc:
* @deprecated The method is deprecated: use .getProvider().retain() instead

-  @Deprecated public boolean retain(boolean asynchronous)

I would prefer this annotation as it was before, above the method declaration (I
don't think we have a specific code style for that, so we should stick with the
one used by Google):
