How to make a singleton for retrofit 2?

Question

If there exists multiple retrofit call, how can i make a singleton of a retrofit, so that there won\'t be repeated codes within the class, thereby get rid of unnecessary cod

Answer 1

i have tried in kotlin :

class RetrofitClient{

    companion object
    {
        var retrofit:Retrofit?=null;
        fun getRetrofitObject():Retrofit?
        {
            if(retrofit==null)
            {
                synchronized(RetrofitClient ::class.java)
                {
                    retrofit=Retrofit.Builder()
                        .addConverterFactory(GsonConverterFactory.create())
                        .baseUrl("YOUR_BASE_URL")
                        .build()
                }
            }
            return retrofit

        }

    }
}

and then:

var service:ServicesInterface?= RetrofitClient.getRetrofitObject()?.create(ServicesInterface::class.java)
