nit: no need to take a vector here, since there's only one module that sits
above content. so this method can just be:

bool OnJNIOnLoad(
    JavaVM* vm,
    base::android::JNIOnLoadDelegate* delegate);

+
+}  // namespace android
+}  // namespace content
+
+#endif  // CONTENT_PUBLIC_APP_CONTENT_JNI_ONLOAD_H_
