Retrofit multipart/form-data image(android)

Question

Many times i try create custom http connect, but now i use libruary retrofit for multipart/form-data. And i have error:

java.lang.NoClassDefFoundError: com.squareup.okhttp.OkHttpClient
            at retrofit.client.OkClient.generateDefaultOkHttp(OkClient.java:35)
            at retrofit.client.OkClient.<init>(OkClient.java:44)

            at dalvik.system.NativeStart.main(Native Method)

at profile.Optional.onActivityResult(Option.java:555) its line:

UploadPhotoRetroService service = ServiceGenerator.createService(UploadPhotoRetroService.class, "https://example.net");

This is my code:

Optional.class

UploadPhotoRetroService service = ServiceGenerator.createService(UploadPhotoRetroService.class, "https://rest.senseloopcore.no/users/image");
                        TypedFile typedFile = new TypedFile("image/jpeg", fileName);
                        service.upload(typedFile, new Callback<String>() {
                            @Override
                            public void success(String result, Response response) {
                                Log.e("result", result);
                            }

                            @Override
                            public void failure(RetrofitError error) {
                                error.printStackTrace();
                            }
                        });

ServiceGenerator.class

public class ServiceGenerator {
    private ServiceGenerator() {
    }

    public static <S> S createService(Class<S> serviceClass, String baseUrl) {
        RestAdapter.Builder builder = new RestAdapter.Builder()
                .setEndpoint(baseUrl)
                .setClient(new OkClient());

        RestAdapter adapter = builder.build();

        return adapter.create(serviceClass);
    }
}

UploadPhotoRetroService

public interface UploadPhotoRetroService {

    @Headers({
            "id: 123",
            "key: 222"
    })

    @Multipart
    @POST("/upload")
    void upload(@Part("Photo") TypedFile file, Callback<String> callback);
}

if you are using gradle and android studio please make sure you have compile 'com.squareup.okhttp:okhttp:2.2.0' in your build.gradle file
