В настоящее время я пытаюсь разработать носимое приложение, которое может загружать файлы с данными акселерометра и гироскопа на мой ПК через FTP.
Я использовал следующий код для запуска FTP-сервера на моем компьютере в Eclipse:
public static void main(String[] args) throws FtpException {
ListenerFactory listenerFactory = new ListenerFactory();
listenerFactory.setPort(2221);
PropertiesUserManagerFactory userManagerFactory = new PropertiesUserManagerFactory();
UserManager userManager = userManagerFactory.createUserManager();
BaseUser user = new BaseUser();
user.setName("Anonymous");
user.setPassword("");
user.setHomeDirectory("C:\\temp");
List<Authority> authorities = new ArrayList<Authority>();
authorities.add(new WritePermission());
user.setAuthorities(authorities);
userManager.save(user);
FtpServerFactory factory = new FtpServerFactory();
factory.setUserManager(userManager);
factory.addListener("default", listenerFactory.createListener());
FtpServer server = factory.createServer();
server.start();
}
Я использую этот метод для подключения к FTP-серверу:
public void connectToFTPServer() throws IOException {
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
Log.i("CONNECT FTP SERVER", "Connecting to FTP Server");
ftpClient.connect(server, port);
ftpClient.login(user, pass);
ftpClient.enterLocalActiveMode();
ftpClient.setFileType(FTP.BINARY_FILE_TYPE);
}
И этот метод для загрузки данных датчика:
public void uploadFileTest()throws IOException {
try
{
if (ftpClient.login("Anonymous", ""))
{
String data = this.getFilesDir() + "/" + "SensorData.txt";
FileInputStream in = new FileInputStream(new File(data));
boolean result = ftpClient.storeFile("SensorData.txt", in);
in.close();
if (result) Log.v("upload result", "succeeded");
ftpClient.logout();
ftpClient.disconnect();
}
}
catch (Exception e)
{
e.printStackTrace();
}
}
Носимое устройство работает на эмуляторе в Android Studio, и даже если кажется, что соединение с FTP-сервером установлено, я получаю следующее сообщение об ошибке наFTP-сервер, когда я пытаюсь загрузить данные датчика.

Пожалуйста, помогите мне, я искал возможное решение в течение нескольких часов.Я уже разрешил порт в брандмауэре Windows и попробовал другие подходы.
Спасибо всем.
