Managing Bitmap memory is critical for mitigating Out-Of-Memory (OOM) risks in visually rich Android apps. While developers know to reduce image sizes, achieving long-term app stability comes from mastering two other key pillars: Reuse and Recycle. This session delivers a practical playbook for optimizing memory performance using modern tools, open-source libraries like Glide and Coil, and system-level APIs.
In this session, you will learn how to diagnose real-world memory regressions using Android Vitals, implement advanced caching (Reuse) patterns with Glide and Coil, and proactively release memory (Recycle) using the onTrimMemory callback.
