Hi, simple problem here. I need to make an Android app that reads a file on PC (picture or movie) and displays it on the screen. WiFi is not an option so it MUST work via USB. It must work on MAC (LINUX acceptable, NOT WINDOWS). Looking around there are 3 ways to do this:

1) reverse tethering. If I manage to have all internet traffic on USB then I can access files on my machine via web server. Looks a bit over complicated though. I looked all over the net and couldn't find out how to do on my WiFi tablet (Galaxy tab7 plus Wifi, Android 3.2, no 3G). Some solutions require enabling the "USB tethering" option on the tables, which is not there for WiFi only. I couldn't get to work the method that "netcfg usb0 dhcp" either.
(Note: WIN users seem to be happy with this UsbPortForwarding.aspx but I need something that runs on Mac or Linux)

2) Direct USB access. Do we have a method to allow an Android app to read a file on the computer? As far as I what I read, the answer is no.

3) USB to ethernet adapters. That would be great but again I still have to find an adapter that will work with Honeycomb


Any hints? pls help, looks like such a simple thing to do but it's really hard without WiFi!

cheers!
