Introduction
With the release of Android OS 16, developers need to update their apps to ensure smooth compatibility. While many apps built for OS 15 will still work, some changes in permissions, background tasks, API behaviors, and UI requirements may break certain functionalities.
This guide explains exactly what needs to be updated.
1. Update Target SDK to API Level 16
Google requires apps to target the latest Android version to unlock all system features and pass Play Store requirements.
Action:
Without this change, the app may face crashes or restricted functionality.
2. Permission Changes in Android 16
Android 16 introduces stricter privacy policies.
Main Changes:
-
Background location access must include a justification screen.
-
Media access permissions split into Photos, Videos, and Music.
-
Auto-reset permissions apply quicker for unused apps.
Update your permission request logic accordingly.
3. Background Task Restrictions
Android 16 reduces background activity for better battery life.
You must update:
-
Foreground service notifications
-
WorkManager job constraints

Android 16 introduces Material You 3.0 dynamic styling.
Update Required:

Updated widget resizing guidelines
Older UI components may appear inconsistent otherwise.
5. Security API Updates
Android OS 16 improves several security libraries.
You should update:
-
Biometric authentication API
-
Encrypted shared preferences
-
Network security configurations
This helps avoid runtime errors.
6. Performance Optimization for New Runtime
The new ART engine in Android 16 may expose performance bottlenecks in older apps.
Recommended actions:
-
Enable R8 code shrinking
-
Optimize images and assets
-
Reduce unnecessary network calls
-
Migrate old libraries to latest versions
Conclusion
Preparing Android OS 15 apps for Android OS 16 is straightforward if you follow the necessary compatibility steps. Updating permissions, UI components, SDK versions, background tasks, and security libraries ensures your app stays stable, fast, and Play Store–ready.
