I'm a novice arduino hacker. I need to connect a hacked Android to an arduino wirelessly but unclear as to which option is best. I've read about the Mega ADK and it is my understanding that a regular board (uno?) can be used with a wireless bluetooth dongle.

What is the best and easiest way to connect to an arduino wirelessly?

You mentioned the Mega ADK, It is quite good, being specifically designed for Android projects, but it is not wireless. If you need wireless, it could be worth taking a look at the Arduino BT. You would have to do the Android app separately, but once you made that, the BT has built-in bluetooth and useful libraries that make connecting easy. Your other option would be a bluetooth shield, of which there are plenty, though none of them are official. There are also WiFi and NFC shields but they are more complicated. Possibly still worth a look.

Two main options. Wifi (or ethernet through a wifi router), or Bluetooth. And not with a regular usb bluetooth dongle. You need a bluetooth module, typically Serial/Uart to Bluetooth.

The third option is a computer (or hacked router) with a serial connection to the arduino, and a program to communicate via wifi with the Android device. This adds an extra layer of complications.
