How to update/upgrade your Android APK during Staged Rollout in Google Play
The answer for the new console:
- Click Publishing Overview in left column;
- Click 'Manage' on the right side
- Enable 'Managed publishing on'
- When the release has been reviewed, it's not released until you decide!
- Log in to your Google Developer Console and select your app
- Select the "APK" view from the left menu
- Click and switch to "Advance Mode" from the the upper right corner
- You will now see "Deactivate" option become available for the version in Staged Rollout
- Click "Deactivate", and ignore the error "This configuration cannot be published..."
- Click on "Upload new APK to Production" button shown on top of the error snippet
- Select the new APK with the same versionName but with a higher versionCode than the old APK in staged rollout.
- Click "Save Draft"
- Click "Publish APK" button appeared on top; don't worry it won't publish at 100%.
At this point it is up to you to Increase the Percentage or remain at the same rate of staged rollout.
Voilà, now you just rolled out a hotfix to only those (small percentage of users) in staged rollout.
