you have also used retrofit 2.0 add dependency in gradle file like below ...

<pre><code> compile 'com.squareup.retrofit2:retrofit:2.3.0'
</code></pre>

show every api call and data into log cat add below depencey ..

<pre><code> compile 'com.squareup.okhttp3:logging-interceptor:3.4.1'
</code></pre>

and after make one class for api set up like below ..

<pre><code>class ApiClient {

companion object {
 val BASE_URL = "https://simplifiedcoding.net/demos/"
 var retrofit: Retrofit? = null
 fun getClient(): Retrofit? {
 if (retrofit == null) {
 val interceptor = HttpLoggingInterceptor()
 interceptor.level = HttpLoggingInterceptor.Level.BODY
 val client = OkHttpClient.Builder().apply {
 readTimeout(20, TimeUnit.SECONDS)
 writeTimeout(20, TimeUnit.SECONDS)
 connectTimeout(20, TimeUnit.SECONDS)
 addInterceptor(interceptor)
 addInterceptor { chain -&gt;
 var request = chain.request()
 request = request.newBuilder()
 .build()
 val response = chain.proceed(request)
 response
 }
 }
 retrofit = Retrofit.Builder()
 .baseUrl(BASE_URL)
 .client(client.build())

 .addConverterFactory(GsonConverterFactory.create())
 .build()

 }

 return retrofit
 }
}
</code></pre>

}

then after make interface to call different type of api like below ...

<pre><code>interface ApiInterface {
@GET(NetworkConstant.DATA) // hear pass your api call
fun getData(): Call&lt;List&lt;Hero&gt;&gt;
</code></pre>

}

make sparate class for network for api value like bellow ..

<pre><code>class NetworkConstant {
companion object{
 const val DATA = "marvel"
}
</code></pre>

}

then after when you call to api and getting response that time used below code ..

<pre><code> private fun getHeroData() {
 val dialog= ProgressDialog(mContext)
 showProgress(dialog)
 var apiInterface: ApiInterface = ApiClient.getClient()!!.create(ApiInterface::class.java)
 var hero: Call&lt;List&lt;Hero&gt;&gt;
 hero = apiInterface.getData()
 hero.enqueue(object : Callback&lt;List&lt;Hero&gt;&gt; {
 override fun onFailure(call: Call&lt;List&lt;Hero&gt;&gt;?, t: Throwable?) {
 closeDialog(dialog)
 Toast.makeText(mContext, t?.message, Toast.LENGTH_SHORT).show()
 Log.d("Error:::",t?.message)
 }

 override fun onResponse(call: Call&lt;List&lt;Hero&gt;&gt;?, response: Response&lt;List&lt;Hero&gt;&gt;?) {
 mHeroDataList.clear()
 if (response != null &amp;&amp; response.isSuccessful &amp;&amp; response.body() != null) {
 closeDialog(dialog)
 mHeroDataList .addAll(response.body()!!)
 setAdapter(mHeroDataList)
 }
 }

 })
}
</code></pre>
