+// Test building mDNS as a standalone, so that it can be imported into other repositories as-is.
+// The mDNS code is platform code so it should use framework-annotations-lib, contrary to apps that
+// should use sdk_version: "system_current" and only androidx.annotation_annotation. But this build
+// rule verifies that the mDNS code can be built into apps, if code transformations are applied to
+// the annotations.
+// When using "system_current", framework annotations are not available; they would appear as
+// package-private as they are marked as such in the system_current stubs. So build against
+// core_platform and add the stubs manually in "libs". See http://b/147773144#comment7.
