is there a way to transfer saves on android or is it just not possible?

not without doing stuff to your phone that we do not recommend or offer any support for, no. If you don't delete the game from your phone then when you install the new version it will keep them. If you deleted the game or otherwise are using a different android device, there's nothing we can do except say to use the option to continue from the latest content when choosing a New Game
