Are you asking for an adroid app or an Ubuntu app? –  belacq Aug 30 '12 at 12:23

If you're asking for an Android app, you might ask over on android.stackexchange.com –  hbdgaf Aug 30 '12 at 13:21

You need a wifi chip that supports host mode for that. Sadly most of them don't. If you can verify that yours supports host mode take a look into hostapd. There are several tutorials available.

As alternative there are some apps in the play store that claim to be able to connect to ad-hoc networks. Those need at last android 4 and root access. A lot of people are having problems with this but it may be worth a try if you haven't tried already.

  1. Click on the Networking indicator.
  2. Choose "Create new wireless network" (or something similar, on my Ubuntu's it's translated to my language)
  3. Type in wireless name/password.

Note that such network will have access to the Internet only if your Ubuntu is connected to it via other means (e.g. wire), for a single wi-fi antenna cannot work as hotspot while being used to connect to some other network.
