i dont have amazon devices but would like to publish some of my apps in there.
will my app which contain google play service work out of the box for amazon owner?
or i must recode everything to fit their environment?
Well, i don’t think you need to work from the start to get your application published over the Amazon store , what needs to be done is you may need to make some changes according to Amazon guidelines I guess there is a need of putting the code over to your application which amazon is going to give you after you register yourself. There is no need to code the application again from the start to get its accepted over the amazon store rather than just some minor changes.
You have no need to any update but you will have to guidelines of amazon.
Just follow the guidelines in Amazon, and you will be fine. It’s not like you have to rewrite a program all over again or something.
