+# This is to prevent renaming two methods in two different interfaces to the
+# same name. The testing .apk has a few classes which implement two interfaces
+# that are never implemented together in the real .apk, and thus would create a
+# conflict. We don't expect the absence of this to cause any issues in the real
+# .apk, since the same classes are still being obfuscated, and the ProGuarded
+# .apk is not then being fed into another run.
