Connect two android phones with wi-fi (without laptop or access point) and send file

Question

Is it possible to connect two android phones by wi-fi, without using a bluetooth/GSM/CDMA/IR? Also, there is no any laptop or wi-fi access points or wi-fi routers.

Answer 1

This is called ad hoc network and has been asked before:

Can Android do peer-to-peer ad-hoc networking?

Android Wifi direct multiple connection ad-hoc

Android ad-hoc / access point connection capabilities

Update:

Short answer: ad hoc is not yet supported on Android so this would not work.

You can use Bluetooth to connect two Android phones in a p2p fashion.

Update 2:

Direct device-to-device connection over Wifi is supported under API 14 in Android 4.0 ICS in package android.net.wifi.p2p. You can test devices capability via FEATURE_WIFI_DIRECT.
