"H" is host (supplies power) and "A" is auto (which means the IOIO will act as host or device depending on whether you plug the A-side or the B-side of the USB cable to it. In the latter case, it is the Android that acts as a host (if it is capable of doing so). The Android will supply power to the IOIO, but it the IOIO is also externally powered, it will not draw any current from this supply. So this is probably the ideal solution in your case.
Otherwise, you can try limiting the current drawn by the Android by gently tweaking the charge limit potentiometer counter-clockwise until the connection is dropped. Then turn it slightly clockwise. It is depending on the specific Android device how much current will actually be drawn in this mode. For some devices it can help drastically while for others it hardly matters.
