We are planning a major upgrade to our App. So the new web services will not support old APK and old web services will not support new APK.
In addition, we want to new APK available to public at the same time as we publish web services.
Can I first submit the production APK for review and keep it ready? So that I can publish both APK and web services at the same time?
Google Play has released scheduled deploy. You can now control the time of the update.
