title: The data that i grab with retrofit does not appear in logcat
body: <p>Hi I'm coding a cryptocurrency app with an API. I'm using retrofit for grabbing data from the Internet I guess ı did everything right but the data does not appear in my logccat
  My main activity is -&gt;</p>
  <pre><code>class MainActivity : AppCompatActivity() {
  
  private val BASE_URL = &quot;https://api.nomics.com/v1/&quot;
  private var cryptoModels: ArrayList&lt;CryptoModel&gt;? = null
  
  override fun onCreate(savedInstanceState: Bundle?) {
      super.onCreate(savedInstanceState)
      setContentView(R.layout.activity_main)
  
      //API Key : b358142f3857509cc2fb3f834b566dc8716cad4d
      //https://api.nomics.com/v1/prices?key=b358142f3857509cc2fb3f834b566dc8716cad4d
  
      loadData()
  }
  
  private fun loadData() {
  
      val retrofit = Retrofit.Builder()
          .baseUrl(BASE_URL)
          .addConverterFactory(GsonConverterFactory.create())
          .build()
  
      val service = retrofit.create(CryptoAPI::class.java)
      val call = service.getData()
  
      call.enqueue(object : Callback&lt;List&lt;CryptoModel&gt;&gt; {
          override fun onResponse(
              call: Call&lt;List&lt;CryptoModel&gt;&gt;,
              response: Response&lt;List&lt;CryptoModel&gt;&gt;
          ) {
  
              if (response.isSuccessful) {
                  response.body()?.let {
                      cryptoModels = ArrayList(it)
  
                      for (cryptoModel: CryptoModel in cryptoModels!!) {
                          println(cryptoModel.currency)
                          println(cryptoModel.price)
                      }
                  }
              }
          }
  
          override fun onFailure(call: Call&lt;List&lt;CryptoModel&gt;&gt;, t: Throwable) {
          }
      })
  }
  </code></pre>
  <p>And my retrofit interface is -&gt;</p>
  <pre><code>interface CryptoAPI {
  
  
  //https://api.nomics.com/v1/
  // prices?key=b358142f3857509cc2fb3f834b566dc8716cad4d
  
  
  @GET (&quot;prices?key=b358142f3857509cc2fb3f834b566dc8716cad4d&quot;)
  fun getData (): Call&lt;List&lt;CryptoModel&gt;&gt;
  </code></pre>
