I have just tried to release an updated version of my game to Google app store and am receiving the following error:
Your app currently targets API level 25 and must target at least API level 26 to ensure it is built on the latest APIs optimized for security and performance. Change your app's target API level to at least 26. Learn how.
The 'Learn how' doesn't really tell me mush as I am still new to setting up releases and so far have had no issues with production deployments until the Google API requirement change in October. This is my first attempt at a release since then. My API level is presently 25 according to Google.
What steps do I need to take to rectify this issue? I am using the most recent version of the API, am I missing a directive for the build file?
