Currently, existing apps (across mobile, Android Auto, Android TV) must target API level 31 or above by August 31, 2023 (target API 30 or up API level 33 for Wear OS). Otherwise, they will stop being discoverable to all Google Play users whose devices run Android OS versions newer than your app’s target API level, as your app wasn’t built to meet the safety and quality standard that these users expect from newer Android OS versions.
Apps with a target level of Android 11 (API level 30)* or lower will not be available to new users running the Android OS higher than apps’ target API after August 31, 2023.
Apps with a target level of Android 10 (API level 29) or lower have not been available to new users running the Android OS higher than apps’ target API after November 1, 2022, or May 1, 2023, if your app had an extension.
