Sorry I didn't realise you were talking about the Android version. Yes that's right the option for splash screens is not there for this platform.
Neil Enns - Adobe mentioned the following a few weeks back:
The Fast Company app is a proof of concept app and isn't built on DPS 2015. There are a few aspects of its UI that were specific to their design, and that we haven't built into the DPS 2015 platform.
I will let him comment further on having splash screens for Android as well.
