Download this .jar file

httpmime-4.1.1.jar and commons-net.jar

        try {

            FTPClient ftpClient = new FTPClient();

            ftpClient.connect(InetAddress
                    .getByName(Your host Url));
            ftpClient.login(loginName, password);
            System.out.println("status :: " + ftpClient.getStatus());

            ftpClient.changeWorkingDirectory(your directory name);

            ftpClient.setFileType(FTP.IMAGE_FILE_TYPE);
                        //Your File path set here 
                        File file = new File("/sdcard/my pictures/image.png");  
            BufferedInputStream buffIn = new BufferedInputStream(
                    new FileInputStream(myImageFile));
            ftpClient.enterLocalPassiveMode();
            ProgressInputStream progressInput = new ProgressInputStream(
                    buffIn);

            boolean result = ftpClient.storeFile(UPLOADFILENAME + ".png",
                    progressInput);

            System.out.println("result is  :: " + result);
            buffIn.close();
            ftpClient.logout();
            ftpClient.disconnect();

        } catch (Exception e) {
            e.printStackTrace();

        }
