# crypto-currencies

## Info

In this app i am going to show you current cryptocurrencies.

> I took MY_API_KEY for free from this website [https://nomics.com/]

## Installation

Using this commands you can get it:

git clone https://github.com/eyrafabdullayev/crypto-currencies.git

## About

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

1) If you are NOT using RXJava

```kotlin

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

        val call = service.getData()

        call.enqueue(object : Callback> {

            override fun onFailure(call: Call>, t: Throwable) {

            }

            override fun onResponse(

                call: Call>,

                response: Response>

            ) {

                if (response.isSuccessful) {

                      response.body()?.let {

                          

                      }

                }

            }            

        });

        

//    and interface CryptoAPI  

       

      @GET("prices?key=YOUR_KEY")

      fun getData(): Call>

```

  2) If you are using RXJava

  

>     At first you must define this variable

```kotlin

      //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

```kotlin

      compositeDisposable = CompositeDisposable()

```   

>     After that

  

  ```kotlin

        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){

        

        }

    

        //and interface CryptoAPI can be like that

    

        @GET("prices?key=YOUR_KEY")

        fun getData(): Observable>

    

```
