问题
I am looking for the best, if any, programmatic way of connecting two or more Android phones to each other through the use of either Bluetooth or preferably, Wi-Fi. Apparently Android devices still do not have ad-hoc Wi-Fi capabilities and I am trying to create a peer based program without the use of any central server.
I want to accomplish this without the use of modification to the phones (no rooting). It is even fine to have a phone act as an access point with no Internet access to its clients if that is possible, I just need a mobile network.
回答1:
I have 2.2 on my Android phone and it does have tethering - it can create a wireless access point then other devices can connect to it.
To prevent it having the internet, just turn mobile internet off.

The short answer is, you can't directly through the SDK. Some phones / revisions may have factory or other support to do so, but you can't rely on the SDK to do this.
