Why specify base::android:: when you are already in the namespace?

+  return base::android::ConvertJavaStringToUTF8(
+      env, static_cast<jstring>(path.obj()));
+}
+
+std::string GetCacheDirectory() {
+  JNIEnv* env = AttachCurrentThread();
+  AutoJObject path = AutoJObject::FromLocalRef(
+      env, Java_PathUtils_getCacheDirectory(
+          env, base::android::GetApplicationContext()));
+  return base::android::ConvertJavaStringToUTF8(
+      env, static_cast<jstring>(path.obj()));
+}
+
+bool RegisterPathUtils(JNIEnv* env) {
+  return RegisterNativesImpl(env);
+}
+
+}  // namespace android
+}  // namespace base
