What's New in Android 16 for App Developers (2026)

Android 16 introduces several changes that developers should be aware of when updating or creating Android applications.

In my recent work updating Android apps to target API level 36, I encountered a number of compatibility changes that required code updates, testing, and UI adjustments. Some of the most important areas include background execution, permissions, storage access, and compatibility with newer SDK requirements.

Before publishing an update, developers should:

• Update the target SDK to API 36.
• Test on Android 16 devices and emulators.
• Verify runtime permissions.
• Review any deprecated APIs.
• Test widgets, notifications, and foreground services.
• Check Play Console policy requirements.

Updating an application is not only about changing the target SDK number. Every major Android release introduces behavioral changes that should be tested carefully to ensure the app continues working correctly.

I will continue publishing practical Android development tips and experiences as I update my own applications.
