Memory Leaks & Performance Considerations: A Cookbook

on YouTube ↗34m

" summary

Android apps leak memory when background work outlives UI lifecycles; coroutines can leak too unless using structured concurrency and cancelable scopes. Practical fixes include using LeakCanary and Android Profiler, nulling view references (e.g. call MapView.destroy), avoiding static Contexts, and preferring coroutine scopes with a CoroutineExceptionHandler or SupervisorJob. AsyncTask (deprecated 2019) and improperly bound services commonly cause leaks. Kotlin bug KT-1622 is fixed in Kotlin 1.4, and the O’Reilly book "Programming Android with Kotlin: Achieving Structured Concurrency with Coroutines" documents patterns.
