1. Google raises the Target API Level requirement annually — new apps must target the latest API level, while updates typically have a 1-year grace period; 2. Plan API level upgrades in Q1 each year to avoid concentrated rejections in Q4; 3. Use the Google Play SDK Console to monitor the compliance status of your third-party SDKs; 4. For projects using NDK/JNI, API level compatibility testing requires extra rigor; 5. Add targetSdkVersion auto-checks to your CI/CD pipeline, triggering warnings 30 days before the current version approaches expiration.
