Running an Android application creates java.lang.NoClassDefFoundError: retrofit.RestAdapter $ Builder

I am making a photo gallery application using the Flickr API on Android (using Eclipse and 4.4 SDK). The project was successfully compiled, but the application will work, as soon as it starts on Nexus 7 (2012), 4.4 is launched again.

The following banks are included in my build path: Modified-1.6.1 okhttp-2.0.0 gson-2.2.4 Picasso-2.3.2

Here are the relevant files:

GalleryApp.java

import retrofit.RequestInterceptor;
import retrofit.RestAdapter;
import utils.Constants;
import android.app.Application;
import apiService.FlickrService;

public class GalleryApp extends Application {

    private FlickrService mFlickrService;

    public synchronized FlickrService getFlickrService() {

        if (mFlickrService == null) {

            RestAdapter restAdapter = new RestAdapter.Builder()
                    .setEndpoint(FlickrService.FLICKR_API_URL)
                    .setRequestInterceptor(new RequestInterceptor() {
                        @Override
                        public void intercept(RequestFacade requestFacade) {
                            requestFacade.addQueryParam("format", "json");
                            requestFacade.addQueryParam("api_key", FlickrService.FLICKR_API_KEY);

                            requestFacade.addHeader(Constants.HTTP_HEADER_ACCEPT, Constants.ACCEPT_APPLICATION_JSON);
                        }
                    })
                    .build();
            /*
            RestAdapter restAdapter = new RestAdapter.Builder().setEndpoint(FlickrService.FLICKR_API_URL)
            //.setConverter(new GsonConverter(GsonUtil.getGsonInstance()))
                    .setClient(new OkClient())
                    .setLogLevel(RestAdapter.LogLevel.FULL)
                    .setRequestInterceptor(new RequestInterceptor() {

                        @Override
                        public void intercept(RequestFacade requestFacade) {
                            // Get responses in JSON
                            requestFacade.addQueryParam("format", "json");
                            requestFacade.addQueryParam("api_key", FlickrService.FLICKR_API_KEY);

                            requestFacade.addHeader(Constants.HTTP_HEADER_ACCEPT, Constants.ACCEPT_APPLICATION_JSON);
                        }
                    })
                    .build();
            */
            mFlickrService = restAdapter.create(FlickrService.class);
        }
        return mFlickrService;
    }
}

FlickrService.java

import models.PhotoResponse;
import retrofit.Callback;
import retrofit.http.GET;
import retrofit.http.Query;

public interface FlickrService {

    public static final String FLICKR_API_KEY = "dcf5dc19f9d4e86ead9722a634907e6e";
    public static final String FLICKR_API_URL = "http://api.flickr.com/services/rest";

    public static final String NO_JSON_CALLBACK = "&nojsoncallback=1";

    @GET("/?method=flickr.photos.search&extras=original_format" + NO_JSON_CALLBACK)
    void searchPhotos(@Query("text") String searchText, @Query("per_page") String perPage,
                      @Query("page") String page, Callback<PhotoResponse> cb);

I had the same error on Android 4.4 and below. This has been associated with multiDexEnabling.

"multiDexEnable true" build.gradle:

defaultConfig {
        minSdkVersion 15
        targetSdkVersion 23
        versionCode 16
        versionName "1.5"
        multiDexEnabled true
    }


android:name="android.support.multidex.MultiDexApplication"

AndroidManifest.xml, :

    <application
            android:allowBackup="true"
            android:icon="@drawable/ic_launcher"
            android:label="@string/app_name"
            android:name="android.support.multidex.MultiDexApplication">
