I think I followed all steps which I have found so far but the download link for my alpha test isn\'t working.
I uploaded the app 3 days ago, created a google group
If your app is published in alpha or beta version :
https://play.google.com/apps/testing/APP_PACKAGE with a browser if the email configured in your phone is a member of the google testers group.permissions in manifest can hide an app of the store !EDIT After you have uploaded your APK file and published it to Alpha or Beta version, you will see a link "manage testers group" or something like that. Click on that link ... you will be asked to add a google group of testers, below the popup you will see a message like this : "share this link with you testers group". Copy that link and send it to the group by mail.
Sorry I am writing with SO android app, I can't paste screenshots therefore ... may be tomorow ;-)
Hope it's ok.
