In GN generally the target name should match the directory name, so use a hyphen
instead.

+  jar_path = "src/CardboardSample/libs/cardboard.jar"
   deps = [
-    "//third_party/android_tools:android_support_v13_java",
+    "../android_protobuf/android_protobuf.gyp:protobuf_nano_javalib",

Can you do absolute paths here (so "//third_party/android_protobuf/...")

   ]
