In my app I have an FTP file browser, and I was wondering the following to try and acheive efficient FTP code:

Should I connect, login, perform actions, then disconnect each time I want to download/upload a file or list files?

or

Should I connect and login when the file browser is loaded, then performs actions whenever is necassary, then at the end disconnect when the file browser is closed?

or do you have any other suggestions of when to connect/disconnect?

Sorry if my question isn't good enough, or is stupid. I'm just curious as some tutorial I've seen they disconnect straight after performing an action and I wasn't sure if you should each time you perform an FTP-related action or not.

Thanks, Alex.

You might have to measure this, but the answer to your question depends on how frequently does the app needs to perform some kind of ftp transfer. If the application needs to be perform lots of ftp transfer then there is no point dropping and creating new connection.

As far as I know, the ftp connection object is not very heavy and the following thread discussed a good pattern on using FTP in android.
