    public static final String DIR_CARD             = Environment.getExternalStorageDirectory().getAbsolutePath();
    public static final String DIR_APP              = DIR_CARD + "/android-downloader";
    public static final int    Download_buffer_Size = 8 * 1024;


    @Override
    public void onCreate() {
        super.onCreate();
        new File(DIR_APP).mkdirs();
    }

 package com.downloader.first;

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


public class filedownloader {

    public static 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();

            File file = new File(filepath);
            if (file.exists()) {
                file.delete();
            }
            ;
            FileOutputStream outputStream = new FileOutputStream(filepath);

            InputStream inputStream = connection.getInputStream();
            byte[] buffer = new byte[G.Download_buffer_Size];
            int len = 0;
            while ((len = inputStream.read(buffer)) > 0) {
                outputStream.write(buffer, 0, len);
            }
            outputStream.close();
        }
        catch (MalformedURLException e) {
            e.printStackTrace();
        }
        catch (IOException e) {
            e.printStackTrace();
        }
    }
