This change allows RROs to reference their own internal resources as expected. Overlays are loaded as shared libraries so they can have their own resource id space that does not conflict with the resource id space of the target or other overlays. References to overlay resources that override target resources now appear as references to the target resources. Overlay values that are inlined into the xml file specified using android:overlayResources are now able to be used at runtime. See go/rro-references for more information.
