+# A list of allowed dependencies for all updatable modules.
+#
+# The list tracks all direct and transitive dependencies that end up within any
+# of the updatable binaries; specifically excluding external dependencies
+# required to compile those binaries. This prevents potential regressions in
+# case a new dependency is not aware of the different functional and
+# non-functional requirements being part of an updatable module, for example
+# setting correct min_sdk_version.
+#
+# To update the list, run:
+# repo-root$ build/soong/scripts/update-apex-allowed-deps.sh
+#
+# See go/apex-allowed-deps-error for more details.
+# TODO(b/157465465): introduce automated quality signals and remove this list.
