خطا در Download فایل از اینترنت در پروژه(حل شد)

با سلام

من از این کد برای دانلود استفاده می کنم:

 
			String url = prdItems.get(0).image_name;
			String fileName = url.substring( url.lastIndexOf('/')+1, url.length() );
			downloadPath = G.DIR_APP + fileName;
			
			Log.i("Log", "fileName: " + fileName);
			Log.i("Log", "URL: " + url);
			Log.i("Log", "Local Download Path: " + downloadPath);
			
			FileDownloader fileDownloader = new FileDownloader();
			fileDownloader.download(url, downloadPath + "/" + fileName );

FileDownloader:

 

import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.net.HttpURLConnection;
import java.net.MalformedURLException;
import java.net.URL;

import android.util.Log;
import clss.ExceptionHelper;

public class FileDownloader {
	
	public void download(String downloadPath, String filePath){
		try {
			URL url =  new URL(downloadPath);
			HttpURLConnection connection  = (HttpURLConnection) url.openConnection();
			connection.setRequestMethod("GET");
			connection.setDoOutput(true);
			connection.connect();
			
			FileOutputStream outputStream = new FileOutputStream(filePath);
			InputStream inputStream = connection.getInputStream();
			byte[] buffer = new byte[32*1024];
			int len = 0;
			while ((len = inputStream.read(buffer)) > 0){
				outputStream.write(buffer, 0, len);
			}
			outputStream.close();
			
			Log.i("Log", "File Downloaded: " + filePath);
			
		} catch (MalformedURLException e) {
			// TODO Auto-generated catch block
			ExceptionHelper.catchMessage(e);
			Log.e("Log","Error Downloading: " + filePath + " From URL: " + downloadPath);
		} catch (IOException e) {
			// TODO Auto-generated catch block
			ExceptionHelper.catchMessage(e);
			Log.e("Log","Error Building Connection");
		}
	}

}

خطای "Error Building Connection" چاپ می شه

ضمنا مسیری که میخوای توش فایل رایت کنی باید حاوی نام پکیج هم باشه - این ریزه کاریا رو بقیه سخت تر میتونن تو کدت ببینن - باید بگی داری چیکار میکنی (12 سال پیش)

این رو ببینید:

با این کد ساخته شده:

 		DIR_APP = context.getFilesDir() + "/Holiday/";
		DIR_DATABASE = DIR_APP + "db/";
		new File(DIR_APP).mkdirs();
		new File(DIR_DATABASE).mkdirs();

می خوام توی این مسیر فایل رو دانلود کنه
