obfs4 bridges are used instead of meek if meek is selected in Tor Browser for Android alpha
In the 9.5 alpha series meek is not used anymore even if meek is selected as pluggable transport. Instead Tor Browser tries to use some obfs4 bridge from the bridge list coming with Tor Browser. That's happening on 9.5a11. 9.0.9 is not affected.
