From what I understand reading This link. It appears to me that the only way to test in app purchase is to write the complete code for in app purchase. And then do a proper build. Upload it to beta release. And then download the app via the opt in link.
But how do I develop it in the first place? Am I expected to write some lines of code and then do a build and upload it? That is a huge turn around time. Is there no way for me to have some test account that I can sign in go google play (on phone) with and then just make purchases?
Currently, my code already handles the products
android.test.purchased
and android.test.canceled
. How do I make it so that I can test my own products Ids? Currently it just says the product you are requesting is not available.
