How to publish beta in the Android store?
I'm trying to allow beta testing of my mobile phone app in the Android games store. I already downloaded the signed apk on the beta tab and added a google + group with some users inside ... but I'm a little surprised that I can not find how to install or even find this application on testers smartphones. I selected myself as a user in a group, but I canโt see the link to the application or something like that. Should the app be visible to beta users in the app store? Or do I need to click the publish button? The info popup reports:
"Your app can only be used by your testers when it is published to Google Play. If your app has no production APK then it will only be visible to Alpha and Beta testers. The link that your testers can use to opt-in will be displayed here when you have published your app."
It seems to me that it should be published. But does this not mean that the beta apk will be transferred to the published area and will no longer be a beta version? I'm afraid that the application will be visible to all users in the game store, not only for my beta testers.
Can someone explain to me how to publish beta only for my testers?
EDIT: It seems that all I need is a missing link. Any idea why?
