content/public contains only interfaces & structs, and static functions. (
https://www.chromium.org/developers/content-module/content-api )

So you'll need to split this up into a ServiceRegistryAndroid (a pure virtual
interface class with no data members) and ServiceRegistryAndroidImpl (somewhere
in content/browser/.., not content/public) which implements
ServiceRegistryAndroid in terms of ServiceRegistryImpl::Data).

There's no need for a service_registry_android.cc, methods like
~ServiceRegistryAndroid() and ServiceRegistryAndroid::From can be declared in
service_registry_android.h and defined in the service_registry_android_impl.cc
file.

  public:
   static bool Register(JNIEnv* env);
+  static ServiceRegistryAndroid* From(ServiceRegistry* registry);
 
-  explicit ServiceRegistryAndroid(ServiceRegistryImpl* service_registry);
-  virtual ~ServiceRegistryAndroid();
+  ~ServiceRegistryAndroid() override;
 
   // Methods called from Java.
   void AddService(
       JNIEnv* env,
       const base::android::JavaParamRef<jobject>& j_service_registry,
       const base::android::JavaParamRef<jobject>& j_manager,
       const base::android::JavaParamRef<jobject>& j_factory,
       const base::android::JavaParamRef<jstring>& j_name);
   void RemoveService(
       JNIEnv* env,
       const base::android::JavaParamRef<jobject>& j_service_registry,
       const base::android::JavaParamRef<jstring>& j_name);
   void ConnectToRemoteService(
       JNIEnv* env,
       const base::android::JavaParamRef<jobject>& j_service_registry,
       const base::android::JavaParamRef<jstring>& j_name,
       jint handle);
 
   const base::android::ScopedJavaGlobalRef<jobject>& GetObj() { return obj_; }
 
  private:

   base::android::ScopedJavaGlobalRef<jobject> obj_;
 
   DISALLOW_COPY_AND_ASSIGN(ServiceRegistryAndroid);
