Android Question How to: Detect failed connection

[Penfound]

I have an app that each time it starts checks whether there is a WiFi or Mobile Data connection, if so, t=it then downloads the latest file via FTP. If there is no internet connection then it simply uses the files already on the device.

However, if there IS internet bit the FTP site is inaccessible, is there a way of checking before waiting for a timeout. Would it work if I ...

Check for internet connection
Ping ftp site
Then download

or is it, because this FTP runs as a separate process that we can't interrupt it?

Cheers

Is there an http server running on the same host?

If yes then you can first send a request with HttpUtils2 (you can set the timeout).
