Мне нужна помощь по Android app, над которой я работаю.
Приложение позволяет пользователю выбрать фотографию из gallery или camera, затем обрезать изображение и, наконец, загрузить изображение в server.
Для обрезки изображения я использовал библиотеку uCrop yalantis и для загрузки фотографии на сервер я использую Retrofit.
Проблема, с которой я столкнулся, заключается в том, что я выбираю image, обрезку и затем, когда я сохраняю его на server, сохраняется изображение ORIGINAL , а не обрезанное изображение.
Может кто-нибудь сказать мне, почему это происходит?
вот мой код:
MainActivity
public class MainActivity extends AppCompatActivity implements IImagePickerLister{
