Error connecting to FTP server using ftp4j in android

Question

// This is my code

public void uploadFile(File fileName){


    FTPClient client = new FTPClient();

    try {

        client.connect(FTP_HOST);
        client.login(FTP_USER, FTP_PASS);
        client.setType(FTPClient.TYPE_BINARY);
        //client.changeDirectory("/schlogger/");

        client.upload(fileName, new MyTransferListener());

    } catch (Exception e) {
        e.printStackTrace();
        try {
            client.disconnect(true);
        } catch (Exception e2) {
            e2.printStackTrace();
        }
    }

}

this is in the mainfist

Try add after client.setType(FTPClient.TYPE_BINARY); code client.setPassive(true); client.noop(); client.setPassive(true); client.noop();
