Every year Google raises the minimum target API level for new submissions and updates. If your app targets an older Android version, it will be rejected from new submissions and eventually removed from existing listings. Here's how to update it.
What Apple said
“Your app targets API level 31, which does not meet the Google Play target API level requirement. New apps must target Android 14 (API level 34) or higher. Please update your app's targetSdkVersion and resubmit.”
Google requires apps to target recent Android API levels to ensure users get modern security and privacy protections. Each year Google sets a deadline for new submissions and existing app updates to reach the current minimum. Falling behind means your app can't be submitted and eventually stops showing to new users on newer Android versions.
While you're at it — Apple also requires these pages for every app.
Fix this rejection, then make sure you're covered on the compliance side too. Apple requires every app to link to a hosted Privacy Policy, Terms of Service, Support page, and Data Deletion page. No link means another rejection — just for a different reason.
