Don't worry about the warning messages. The first message is because you probably don't have any users in your beta / alpha channel.
The second warning, is because for a while now, we are supposed to use .aab instead of .apk, for better management and distribution. However this is not available in AIR (technically the latest AIR33, supports android app bundles, but only if you are not using ANEs). Concerning the keystore, you don't need to upload it to the store if you didn't before. You can keep using your old .p12 file and it will be fine. However, uploading it to the store, saves you from the troubles of misplacing it and getting locked out. -- Sent from: http://apache-flex-users.2333346.n4.nabble.com/
