Android Developer Preview Releases
Android developer preview releases are early versions of upcoming Android OS updates made available to developers for testing new features, APIs, and compatibility. They help developers prepare apps ahead of the official public launch, ensuring smoother transitions and better app performance.
Android developer preview releases
1 ) Early Release of Android 16 Developer Preview
Google released the first developer preview of Android 16 in November 2024, targeting a Q2 2025 final release.
This is a shift from previous years with an earlier release intended to help device manufacturers deliver updates faster.
Developers can test the preview on Pixel 6 series and newer devices.
2 ) Focus on Privacy and Health Data
Android 16 introduces an embedded photo picker API allowing users to share specific media without granting full storage access.
A new Health Connect API supports secure management of health data in FHIR format, enhancing privacy akin to iOS health features.
The update includes enhancements to Privacy Sandbox, aimed at replacing Android's advertising ID system to improve user privacy while maintaining ad capabilities.
3 ) Twice Yearly API Release Plan for 2025
Alongside the major Android 16 release in Q2, a second minor SDK release is scheduled for Q4 2025 with new APIs and improvements.
The Q4 release will focus on features and bug fixes without app impacting behavior changes.
Quarterly updates will continue, supporting continuous improvements in app quality and device compatibility.
4 ) New API Versioning and Compatibility Tools
Support continues for SDK_INT and VERSION_CODES constants to manage API level checks.
New constants like SDK_INT_FULL and VERSION_CODES_FULL allow distinguishing between major and minor releases.
Build.getMinorSdkVersion() helps developers identify minor SDK versions for fine grained compatibility handling.
These APIs are in preview and subject to changes; feedback is encouraged.
5 ) Developer Impact and Timeline
The earlier Q2 release requires developers to complete compatibility tests earlier than past years.
Google aims for platform stability by March 2025, allowing time for app updates before the public release.
A public beta program will launch in January 2025, with additional developer previews planned through December 2024.
This accelerated and more frequent release cadence highlights Google's commitment to faster innovation, enhanced privacy, and developer tools for the Android ecosystem.
