Google is pretty poor providing Android frameworks at the same level as any *Kit available on iOS.
They leave it to the open source community and only due to lots of pressure, did they finally released something like "Android Architecture Components".
Tango as other mentioned is not actually there.
Stuff like CoreML, MetalKit, Model I/O, GameKit, SceneKit, SpriteKit, Image I/O,... just doesn't exist at the same level as Apple.
Well, some of them do exist, but as open source projects without any support from Google.
