I'm developing a Glass app using GDK and Mirror API. I'm stuck with the GDK Authentication feature launched in XE16. I'm getting a response '404 Not Found' when trying to insert the account with the Mirror API:
POST https://www.googleapis.com/mirror/v1/accounts/{userToken}/com.example.myapp/username%40email.com
I'm not sure if I have to upload my app first to glassware to be able to test it. The authentication doc kind of said that:
https://developers.google.com/glass/develop/gdk/authentication
It is possible to upload my app to test this functionality without making it public to others?
