The LiPo charger / boost is rated to 5V @ 1A. It is probably a bit low for charging a cell-phone AND driving a couple of motors reliably. I don't think the way you intended to connect things would work, since that board probably won't pass the USB connection through, but only happens to use USB connectors for power.
What you need is something like: - 2S LiPo (7.4V) connected to the IOIO JST input. - IOIO connected to Android over USB, where the IOIO is the host (would charge the Android). - A LiPo solar charger capable of charging a 2S pack, connected in parallel to the battery (or to the IOIO Vin/GND terminals). If you can't find a 2S solar charger, your next best bet is to stick to the 1S configuration and find a boost capable of about 2A-3A of *output*. If you can't find one that is integrated with a solar charger, you may use two discrete modules (boost, solar charger). If possible, I would recommend boosting to higher than 5V and powering the IOIO through the JST input. This has the advantage of using the IOIO on-board 5V regulator with some margin, to smooth out any glitches in the input voltage.
