About

There are two cases: if you are not using RXJava or if you are using it

1. If you are NOT using RXJava

      val service = retrofit.create(CryptoApi::class.java)
        val call = service.getData()

        call.enqueue(object : Callback<List<CryptoModel>> {
            override fun onFailure(call: Call<List<CryptoModel>>, t: Throwable) {

            }

            override fun onResponse(
                call: Call<List<CryptoModel>>,
                response: Response<List<CryptoModel>>
            ) {
                if (response.isSuccessful) {
                      response.body()?.let {
                          
                      }
                }
            }            

        });
        
//    and interface CryptoAPI  
       
      @GET("prices?key=YOUR_KEY")
      fun getData(): Call<List<CryptoModel>>

2. If you are using RXJava

At first you must define this variable

      //it used for when the Activity has been destroyed closing calls
      private var compositeDisposable: CompositeDisposable? = null

Then you must initialize this variable in onCreate() method like below

      compositeDisposable = CompositeDisposable()

After that

      val retrofit = Retrofit.Builder()
          .baseUrl(BASE_URL)
          .addConverterFactory(GsonConverterFactory.create())
          .addCallAdapterFactory(RxJava2CallAdapterFactory.create())
          .build().create(CryptoApi::class.java)

      //we can add other calls to 'compositeDisposable' as we trying below
      compositeDisposable?.add(retrofit.getData() //getting data
          .subscribeOn(Schedulers.io()) //here we trying listen to it on another thread
          .observeOn(AndroidSchedulers.mainThread()) //here we trying execute data on main thread
          .subscribe(this::handleResponse)) // sending response to the method


      private fun handleResponse(cryptoList: List<CryptoModel>){
      
      }
  
      //and interface CryptoAPI can be like that
  
      @GET("prices?key=YOUR_KEY")
      fun getData(): Observable<List<CryptoModel>>
