file sharing between android devices without bluetooth and internet connection what if you dont have internet service on your android devices but still want to use the wifi to transfer files. I have found there are many ways to transfer files but they all use the browser and need it to get on line and bluetooth is not an option on my tablet which is android also
I use ES file explorer.  It lets me access my home network disk drives via WiFi.

To test this, I opened my phone to the DCIM photo area, press/hold one file, "copy to" then navigated UP from the SD card, where it gave me my network connections (which I'd already browsed to with ES File Explorer).

I could then navigate down to a directory and say [OK] and the file went to my NAS

I was able to view it (or transfer it) on another machine just fine.  

IF you want to use WiFi directly from android device to android device, then both need to be able to go into "Ad Hoc" mode which means something like "without a central WiFi router".  I doubt that's in the "settings" but there may be something in the app store.  (Sorry I refuse to use that new name Google gave the app store, as I am serious, not playing around).  haha.
