+# Use the LOCAL_JAVA_LANGUAGE_VERSION if it is set, otherwise
+# use one based on the LOCAL_SDK_VERSION. If it is < 24
+# pass "1.7" to the tools, if it is unset, >= 24 or "current"
+# pass "1.8".
+#
+# The LOCAL_SDK_VERSION behavior is to ensure that, by default,
+# code that is expected to run on older releases of Android
+# does not use any 1.8 language features that are not supported
+# on earlier runtimes (like default / static interface methods).
+# Modules can override this logic by specifying
+# LOCAL_JAVA_LANGUAGE_VERSION explicitly.
