Possible answers:

Before ICS and non rooted devices

There is no way you can connect to a device over wifi. There is no API to do. Bluetooth is your best option or user interaction.

Before ICS and rooted devices

I am not sure if someone hacked the code, but when I tried to do an automatic connection to a wifi spot I noticed:

• The api is hidden inside the SDK.
• The method that does the connection checks the thread who ask for it. If it's not the os thread, it throws an exception.

Using ICS

With ICS there is a new way to connect devices through wifi called Wi-Fi Direct. Here is a link with some demos.
