Networking Library : Retrofit

STEP-1: Library

    compile('com.squareup.retrofit2:retrofit:2.1.0') {

        exclude module: 'okhttp'

    }

STEP-2: API Client

public class APIClient {

    private static Retrofit retrofit = null;

    public static Retrofit getClient(String url) {

        HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();

        interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);

//        OkHttpClient client = new OkHttpClient.Builder().addInterceptor(interceptor).build();

        OkHttpClient client = new OkHttpClient.Builder().connectTimeout(60, TimeUnit.SECONDS)

                .readTimeout(60,TimeUnit.SECONDS).addInterceptor(interceptor).build();

        retrofit = new Retrofit.Builder()

                .baseUrl(url)//localhost

                .addConverterFactory(GsonConverterFactory.create())

                .client(client)

                .build();

        return retrofit;

    }

}

3. API Interface

    @POST("api/email_verification.json")

    Call<AddFolderResponse> emailVerification(@Body EmailVerificationRequest emailVerificationRequest);

    @Multipart

    @POST("api/set_profile_picture.json")

    Call<AddFolderResponse> profileImageUpload(@Part MultipartBody.Part file, @Part("file[]") RequestBody id_proof, @Query("token") String token);

4. APP Call

    public void callWebServiceForEmailVerification(){

        String token = prefs.getString(CONSTANTS.LOGGED_TOKEN);

        EmailVerificationRequest emailVerirequest = new EmailVerificationRequest();

        emailVerirequest.token = token;

APIInterface apiInterface = APIClient.getClient(CONSTANTS.BASE_URL).create(APIInterface.class);

        if(NetworkClass.getInstance().checkInternet(PaidSubscriberDashboardActivity.this) == true){

            ProgressClass.getProgressInstance().showDialog(PaidSubscriberDashboardActivity.this);

            Call<AddFolderResponse> call = apiInterface.emailVerification(emailVerirequest);

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

                @Override

                public void onResponse(Call<AddFolderResponse> call, Response<AddFolderResponse> response) {

                    ProgressClass.getProgressInstance().stopProgress();

                    try {

                        if (response.isSuccessful()) {

                            if (response.body().getMessage().getSuccess().equalsIgnoreCase("success")) {

                                showAlertMsg("Alert", "Verfication email sended. Check your mail and follow instruction");

//                            AlertDialogSingleClick.getInstance().showDialog(SubscriberDashboardActivity.this, "Email Alert", "Verfication email sended. Check your mail and follow instruction");

                            }

                        }

                    }catch (NullPointerException npe){

                        Log.e(TAG, "#Error : "+npe, npe);

                        showSnackBar();

                    }

                }

                @Override

                public void onFailure(Call<AddFolderResponse> call, Throwable t) {

                    call.cancel();

                    Toast.makeText(PaidSubscriberDashboardActivity.this, "Something went wrong!", Toast.LENGTH_SHORT).show();

                    ProgressClass.getProgressInstance().stopProgress();

                }

            });

        }else {

            NetworkDialogHelper.getInstance().showDialog(PaidSubscriberDashboardActivity.this);

        }

    }
