Retrofit 2 How to Make Same Request Multiple Times

public void makeGetRequest() {


    Retrofit.Builder builder = new Retrofit.Builder().baseUrl("https://desolate-beach-17272.herokuapp.com");
    Retrofit retrofit = builder.build();


    RetrofitInterface retrofitInterface = retrofit.create(RetrofitInterface.class);


    Call<ResponseBody> call = retrofitInterface.downloadFileByUrl("downloadFile/beach.jpg");


    call.enqueue(new Callback<ResponseBody>() {
        @SuppressLint("StaticFieldLeak")

        // returns the response if everything is okay
        @Override
        public void onResponse(Call<ResponseBody> call, final Response<ResponseBody> response) {

            try {
                Log.d("Success" , " " + response.body().bytes().length);
            } catch (IOException e) {
                e.printStackTrace();
            }
        }


        @Override
        public void onFailure(Call<ResponseBody> call, Throwable t) {
            Log.d("FAIL", "oops");

        }
    });

I have this code and it makes a get request to my server with the async method. What I want is to make the same request multiple times. For example, I want to make get request 100 times. I don't want to use observables or other external libraries if possible. Is there anyone who can help me with that?

You can make call multiple times just see the below code where I have used methods for this purpose. In onResponse method after performing operation on data you get from server you can make another call to the same API by using a variable sizeOfCall and decrementing it untill it equals to zero. Below is the full code for it.

public class RequestActivity extends AppCompatActivity {

    int sizeOfCall = 100;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_request);

      callAPI();
    }

 private void callAPI(){
    Retrofit.Builder builder = new Retrofit.Builder().baseUrl("https://desolate-beach-17272.herokuapp.com");
    Retrofit retrofit = builder.build();
    RetrofitInterface retrofitInterface = retrofit.create(RetrofitInterface.class);
    Call<ResponseBody> call = retrofitInterface.downloadFileByUrl("downloadFile/beach.jpg");

    // Call API
    makeGetRequest(call);
}

 private void makeGetRequest(Call<ResponseBody> call) {

call.enqueue(new Callback<ResponseBody>() {

   @SuppressLint("StaticFieldLeak")

    // returns the response if everything is okay
    @Override
    public void onResponse(Call<ResponseBody> call, final Response<ResponseBody> response) {

        try {
            Log.d("Success", " " + response.body().bytes().length);
            // Perform your operations here and call API againg after that
            sizeOfCall--;
            if (sizeOfCall > 0) {
                callAPI();
                } else {
                 // No more calls needed
                 }
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }


            @Override
            public void onFailure(Call<ResponseBody> call, Throwable t) {
                Log.d("FAIL", "oops");

            }
        });
    }
}

Create a broadcast reciever and put your retrofit request in that. Now call it using alarm manager.

public class YourBroadCastReciever extends BroadcastReceiver{



    @Override
    public void onReceive(Context context, Intent intent) {

            yourRetrofitCode();

    }

    private void yourRetrofitCode(){
        Retrofit.Builder builder = new Retrofit.Builder().baseUrl("https://desolate-beach-17272.herokuapp.com");
    Retrofit retrofit = builder.build();


    RetrofitInterface retrofitInterface = retrofit.create(RetrofitInterface.class);


    Call<ResponseBody> call = retrofitInterface.downloadFileByUrl("downloadFile/beach.jpg");


    call.enqueue(new Callback<ResponseBody>() {
        @SuppressLint("StaticFieldLeak")

        // returns the response if everything is okay
        @Override
        public void onResponse(Call<ResponseBody> call, final Response<ResponseBody> response) {

            try {
                Log.d("Success" , " " + response.body().bytes().length);
            } catch (IOException e) {
                e.printStackTrace();
            }
        }


        @Override
        public void onFailure(Call<ResponseBody> call, Throwable t) {
            Log.d("FAIL", "oops");

        }
    });

    }
}

now call using this code :

 Intent sendDeviceInfoIntent = new Intent(this, YourBroadCastReciever.class);
       PendingIntent yourintent= PendingIntent.getBroadcast(this, 0, sendDeviceInfoIntent, 0);
        alarmManager.setRepeating(AlarmManager.ELAPSED_REALTIME, SystemClock.elapsedRealtime()+1000, 60000, yourintent);

so that every 5 min this will call your broadcast reciever and this will also works in background
