Why Google enforces API target thresholds, and how it impacts app visibility on older devices.
Google Play requires Android developers to update their apps targeting newer API levels on an annual schedule. Keeping your `targetSdkVersion` aligned with the latest Android release is not optional; it is a core requirement to maintain app availability in the Play Store.
Targeting a newer API level ensures that your app runs with the latest performance optimizations, privacy enhancements, and security rules of the Android OS. If Google allowed apps to target very old SDK versions indefinitely, developers could bypass permission check overrides introduced in newer versions of Android.
Every year, Google sets a deadline (typically around August 31st) by which:
Open your project's module-level `build.gradle` file. Find `targetSdkVersion` (or `targetSdk`) in the `defaultConfig` block and change it to the target version number. Clean, rebuild, and resolve any compile-time errors or deprecated APIs.
