Finally, i had this fixed, looks like i had to start fresh to build it and had to amend requirements..These examples at https://github.com/kivy-garden/garden.mapview/tree/master/examples are really good to have the mapview work on Android. Also follow this link carefully https://github.com/kivy-garden/garden.mapview for better ideas :)
