When you upload an APK, it must meet Google Play’s target API level requirements.
Starting on August 31, 2023:
-
New apps must target Android 13 (API level 33) or higher; except for Wear OS apps, which must target a version between Android 11 (API level 30) and Android 13 (API level 33), inclusive.
-
App updates must target Android 13 or higher and adjust for behavioral changes in Android 13; except for Wear OS apps, which must target Android 11.
Permanently private apps—which are restricted to users in a specific organization and are intended for internal distribution only—aren’t required to meet the target API level requirements.
This also means making your app work with the new features, so e.g. you may need to implement a flow to request certain permissions that you were previously getting automatically.
