No there isn't, however the current build is just a prototype so you're not missing too much. However for the next update I'll see if I can package an android version.
So unfortunately, Ren'Py doesn't have Android support built in natively and the plug-ins required to get it up and running are a bit difficult so I'm not sure it's worth building an android version for prereleases. But I'm open to revisiting it for the full release!
