FTP client

找尋可在Android上使用的FTP client library，用於傳輸檔案到FTP server中

• edtFTPJ
• License: LGPL
• 付費版具Security
• FTPClient
• License: ASF

決定使用FTPClient

• 將上面二種library參考到Android程式當中，皆會發生NoClassDefFoundError
• 解法：將library直接匯入到程式的libs資料夾中
• 由於上面的原因，故採用較小容量的FTPClient

Usage

public class MainActivity extends Activity {

 private static final String TAG = "MainActivity";
 
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        int port = 21;
        
        String ftpAddress = "127.0.0.1";
        String username = "potato";
        String password = "123456";
        String root = "/sdcard";
        String remoteRoot = "/test";
        
        FileInputStream inputStream = null;  
        FTPClient client = null;

        try {
            client = new FTPClient();            

            client.setConnectTimeout(1000);
            client.connect(ftpAddress, port);
            client.login(username, password);
            
            client.setFileType(FTP.BINARY_FILE_TYPE);
            client.enterLocalPassiveMode();

            for(int i = 0;i<3;i++)
            {
             try {
          inputStream = new FileInputStream(root + "/" + i + ".jpg");
          } catch (FileNotFoundException e) {
           e.printStackTrace();
          }
                client.appendFile(remotRoot + "/" + i + ".jpg", inputStream);
             inputStream.close();
            }            
            client.disconnect();
            
        } catch (IOException ioe) {
            ioe.printStackTrace();
        }
        
    }
}
