的Android异步FTP

Question

我试图使用异步任务通过FTP发送一个文件，这里是我迄今发现的，但不能把它发送文件：

package com.hdwinc.hdworderentry; 

import java.io.BufferedInputStream; 
import java.io.File; 
import java.io.FileInputStream; 
import java.io.IOException; 
import java.net.SocketException; 
import java.net.UnknownHostException; 

import org.apache.commons.net.ftp.FTPClient; 
import org.apache.commons.net.ftp.FTPReply; 

import android.os.AsyncTask; 
import android.util.Log; 

public abstract class HDWFTP_Upload extends AsyncTask{ 
//void FTP_DATA_UPLOAD(String FULL_PATH_TO_LOCAL_FILE) 


protected Long doInBackground(String... FULL_PATH_TO_LOCAL_FILE) { 
    // encapsulate FTP inside a A sync task 

    { 
    System.out.println("Entered FTP transfer function"); 

    FTPClient ftpClient = new FTPClient(); 
    int reply; 
    try { 
    System.out.println("Entered Data Upload loop!"); 
     ftpClient.connect(ServerName,21); 
     ftpClient.login(Username, Password); 
     ftpClient.sendCommand("QUOTE SITE NAMEFMT 1"); 
     ftpClient.changeWorkingDirectory("/OPTICON/"); 
     System.out.println("Entered Data Upload loop!"); 


     reply = ftpClient.getReplyCode(); 


     if(FTPReply.isPositiveCompletion(reply)){ 
     System.out.println("Connected Success"); 
     }else { 
     System.out.println("Connection Failed"); 
     ftpClient.disconnect(); 
     } 



     if (ftpClient.getReplyString().contains("250")) { 
      ftpClient.setFileType(org.apache.commons.net.ftp.FTP.BINARY_FILE_TYPE); 
      BufferedInputStream buffIn = null; 
      System.out.println("Created an input stream buffer"); 
      System.out.println(FULL_PATH_TO_LOCAL_FILE.toString()); 

      buffIn = new BufferedInputStream(new   FileInputStream(FULL_PATH_TO_LOCAL_FILE[0])); 
      ftpClient.enterLocalPassiveMode(); 

      System.out.println("Entered binary and passive modes"); 
      //Handler progressHandler=null; 
    //ProgressInputStream progressInput = new ProgressInputStream(buffIn, progressHandler); 

      //Code to Extract name from the string. 
      //http://stackoverflow.com/questions/10549504/obtain-name-from-absolute- path-substring-from-last-slash-java-android 
      String Picture_File_name = new File(FULL_PATH_TO_LOCAL_FILE[0]).getName(); 


      boolean result = ftpClient.storeFile(Picture_File_name, buffIn);  //localAsset.getFileName() 
      //ProgressInputStream progressInput = new ProgressInputStream(buffIn, progressHandler); 

      if (result){ 
      System.out.println("Success"); 
      } 

      //boolean result = ftpClient.storeFile("TEST.jpg", progressInput); 
      System.out.println("File saved"); 


      //buffIn.close(); 
      ftpClient.logout(); 
      ftpClient.disconnect(); 
     } 

    } catch (SocketException e) { 
     Log.e("Citizen Cam FTP", e.getStackTrace().toString()); 
     System.out.println("Socket Exception!"); 
    } catch (UnknownHostException e) { 
     Log.e("Citizen Cam FTP", e.getStackTrace().toString()); 
    } catch (IOException e) { 
     Log.e("Citizen Cam FTP", e.getStackTrace().toString()); 
     System.out.println("IO Exception!"); 
    } 

    return null; 
} 


} 


} 

我将如何调用它另一项活动？我有我的订单活动创建一个文件，我需要将其发送到服务器。

我删除了每个#Squonk的抽象引用，并查看了#Mike M提供的两个页面，并提出了一个解决方案。

谢谢你们。

public class HDWFTP_Upload extends AsyncTask <String, Void, Long>{ 



protected Long doInBackground(String... FULL_PATH_TO_LOCAL_FILE) { 

    { 


    FTPClient ftpClient = new FTPClient(); 
    int reply; 
    try { 
    System.out.println("Entered Data Upload loop!"); 
     ftpClient.connect(servername,21); 
     ftpClient.login(user, pass); 
     ftpClient.sendCommand("QUOTE SITE NAMEFMT 1"); 
     ftpClient.changeWorkingDirectory("/OPTICON/");   


     reply = ftpClient.getReplyCode(); 


     if(FTPReply.isPositiveCompletion(reply)){ 
     System.out.println("Connected Success"); 
     }else { 
     System.out.println("Connection Failed"); 
     ftpClient.disconnect(); 
     } 



     if (ftpClient.getReplyString().contains("250")) { 
      ftpClient.setFileType(org.apache.commons.net.ftp.FTP.BINARY_FILE_TYPE); 
      BufferedInputStream buffIn = null; 
      System.out.println("Created an input stream buffer"); 
      System.out.println(FULL_PATH_TO_LOCAL_FILE.toString()); 

      buffIn = new BufferedInputStream(new FileInputStream(FULL_PATH_TO_LOCAL_FILE[0])); 
      ftpClient.enterLocalPassiveMode(); 

      System.out.println("Entered binary and passive modes"); 

      String Picture_File_name = new File(FULL_PATH_TO_LOCAL_FILE[0]).getName(); 


      boolean result = ftpClient.storeFile(Picture_File_name, buffIn); 

      if (result){ 
      System.out.println("Success"); 
      } 


      System.out.println("File saved"); 



      ftpClient.logout(); 
      ftpClient.disconnect(); 
     } 

    } catch (SocketException e) { 
     Log.e("HDW FTP", e.getStackTrace().toString()); 
     System.out.println("Socket Exception!"); 
    } catch (UnknownHostException e) { 
     Log.e("HDW FTP", e.getStackTrace().toString()); 
    } catch (IOException e) { 
     Log.e("HDW FTP", e.getStackTrace().toString()); 
     System.out.println("IO Exception!"); 
    } 

    return null; 

    } 




} 

与调用：

new HDWFTP_Upload().execute(uploadFile);
