Looper.prepare();
FTPClient client = new FTPClient();
try {
boolean result = false;
FileInputStream fis = null;
client.connect(server);
client.enterLocalPassiveMode();
client.login(user, pass);
client.makeDirectory("/public_html/"+str); ///str is a name of remote folder
client.setFileType(FTP.BINARY_FILE_TYPE);
client.setFileTransferMode(FTP.BINARY_FILE_TYPE );

String path1 = Environment.getExternalStorageDirectory() + "/index.htm";
File f = new File(path1);
String testname = f.getName();
