I just inspired by Google's Demo and created a library, which can add LiveData support for Retrofit. The usage is simple:

Retrofit.Builder()
            .baseUrl("https://api.github.com/")
            .addConverterFactory(GsonConverterFactory.create())
            .addCallAdapterFactory(LiveDataCallAdapterFactory())
            .build()
            .create(GithubService::class.java)
            .getUser("shawnlinboy").observe(this,
                Observer { response ->
                    when (response) {
                        is ApiSuccessResponse -> {
                          //success response
                        }
                        else -> {
                            //failed response
                        }
                    }
                })
