Android is broadening excess memory usage enforcement. 🤖

Preparing your app for broader memory limits

https://android-developers.googleblog.com/2026/08/app-broader-memory-limits.html

A great user experience is central to Android’s mission, and delivering on that promise requires keeping devices fast, responsive, and reliable. This is why memory optimization is more critical than ever. Across the ecosystem, new devices are maintaining or even decreasing their physical memory capacity in response to memory price increases, yet users continue to expect the same seamless, high-performance app experience.

In Android 17, we introduced per-app memory limits, starting with Pixel devices, to help protect the overall user experience from applications using excess memory and causing system-wide slowdowns. Over the coming year, an increasing number of manufacturers will leverage the Android per-app memory limits across their portfolio of device RAM configurations from 4GB to 16GB+ devices. If your app exceeds these limits, it will be slowed down and may be terminated. Optimizing your app’s memory footprint is essential to preventing OS throttling and maintaining a seamless user experience.

📚 Curated articles to understand Compose internals and optimize Jetpack Compose performance.

Understanding the Jetpack Compose mechanism is important, as it directly impacts your application’s performance. Jetpack Compose introduces a new paradigm in declarative UI, driving innovative UI techniques. While the benefits of declarative UI are significant, it also presents challenges in terms of stability and UI updates. This issue is not unique to Jetpack Compose; it also affects other declarative UI frameworks like React and Flutter. These challenges are inherent to all frameworks that use a declarative approach and we can learn across all those various frameworks.
