I haven't yet written a wiki page about it. In short:
1. Some Android devices support being the USB host, some don't. 2. When connecting such a device to the IOIO, the USB cable itself determines who will be the host (the "A" side of the cable) and who will be the device (the "B" side). 3. The OTG adapter provided with your IOIO may be compatible with your Android. If so, having the adapter on the Android side will cause it to become host. Some Android devices don't accept the micro-A connector despite supporting host mode. For those, you'd need to buy a very similar cable to the adapter cable, only with a (non-standard) micro-B connector on the male side. 4. Regardless of software / firmware / anything else, if you are able to get the red power LED on the IOIO to turn on without external power supply, you're probably good to go and any problems you might have can probably be sorted out with following the right steps in building the Android app. Otherwise, the tablet may not support host mode, or you're doing something wrong with the connection.
