Upload can be done using below steps

Step 1: Create a method with below code

UploadPhotoRetroService service = ServiceGenerator.createService(MyActivity.class, "base-url");
TypedFile typedFile = new TypedFile("image/jpeg", new File(imagePath));
service.upload(typedFile, new Callback<String>() {
    public void success(String result, Response response) {
        // success call back    
    public void failure(RetrofitError error) {

Step 2: Create Interface as below

public interface UploadPhotoRetroService {
    void upload(@Part("Photo") TypedFile file, Callback<String> callback);

Step 3: Create class as below

public class ServiceGenerator {

    private ServiceGenerator() {

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

        RestAdapter adapter = builder.build();

        return adapter.create(serviceClass);
