Android 15 Release to AOSP
Article Summary
Android 15 just dropped to AOSP, and Google's bringing some serious developer firepower. Edge-to-edge enforcement, 16KB page size support, and a complete overhaul of how we handle app profiling on user devices.
Google officially released Android 15 to the Android Open Source Project, with rollout starting on Pixel devices in the coming weeks and expanding to Samsung, OnePlus, Xiaomi, and others in the following months. The release focuses on developer productivity, privacy enhancements, and better experiences for tablets and foldables.
Key Takeaways
- Edge-to-edge now mandatory for apps targeting SDK 35 with transparent system bars
- 16KB page sizes show 5-10% performance boost but use 9% more memory
- New profiling APIs let apps request heap dumps and traces from user devices
- Private Space feature requires special handling for medical, launcher, and app store apps
- PDF renderer now supports password protection, annotations, form editing, and search
Android 15 makes edge-to-edge the default, introduces device profiling capabilities, and adds 16KB page size support that boosts performance by up to 10%.
About This Article
Developers struggled to understand how their apps used storage. They couldn't easily see the breakdown across APK splits, AOT code, dex metadata, and libraries, making it hard to optimize effectively.
Google added the StorageStats.getAppBytesByDataType() API in Android 15. Now developers can track exactly how much storage each component of their app consumes.
With this data, developers can identify which parts of their app take up the most space and optimize accordingly. This leads to smaller apps and better performance on user devices.
