Xcode stacks with Android tools means more Xcode versions available for cross-platform developers. ✨
Previously there were hybrids stacks on Bitrise for Xcode + Android, which were initially used by Xamarin developers. The limitation of this was that there were only 2 hybrid stacks with the same Xcode version.
But if we added Android to every Xcode stack, the users could select the Xcode version.

So from now on, the hybrid stacks will be used by Xamarin developers only and all the other cross-platform devs will be able to use the Xcode ones. This means that all of our stacks have an Android SDK installed (either the default or the one for Xamarin).
For native Android projects the suggested stack remains the Linux based stack, but for cross-platform projects where the Xcode version does matter, they should pick the Xcode stack with the right Xcode version.
Ex-hybrid stacks are called VS4MAC and Xcode stack names will be along the lines of "Xcode 9.4.x with Android tools"
