мом деле, я новичок в этой области. Возникла некоторая проблема во время загрузки изображения. Процесс автоматически приостанавливается через некоторое время. Я прилагаю свой код ниже. Пожалуйста, кто-нибудь поможет мне решить эту проблему.

ServerResponse.java

public class ServerResponse {

// variable name should be same as in the JSON response from PHP

@SerializedName("success")
boolean success;
@SerializedName("success_msg")
//@SerializedName("message")
String message;

String getMessage() {return message;
}

boolean getSuccess() {
    return success;
}
}

ApiClient.java

 public class ApiClient {



// public static final String BASE_URL="http://www.mytriangle.net16.net";
  public static final String BASE_URL="http://bsenterprise.in/webservice/";
 // public static final String BASE_URL = "http://mushtaq.16mb.com/";
private static Retrofit retrofit = null;
public static int unique_id;



public static Retrofit getClient() {
    if (retrofit==null) {
        retrofit = new Retrofit.Builder()
                .baseUrl(BASE_URL)
                .addConverterFactory(GsonConverterFactory.create())
                .build();
    }
    return retrofit;
}
}

ApiService.java (интерфейсный класс)

public interface ApiService {


@Multipart

@POST("imageupload-1.php?")
//@POST("retrofit_example/upload_image.php")
Call<ServerResponse> uploadFile(
                                @Part MultipartBody.Part file1,
                               // @Part MultipartBody.Part file2,
                               //
                               // @Part("file") RequestBody name,
