The Memory Leak Apocalypse: Why Your Android App Still Bleeds RAM in 2025 🧟‍♂️

#androiddev #memoryleak #kotlin #appperformance

Think Jetpack Compose and coroutines saved you from memory leaks?

Sorry to break it to you… the RAM-eating monster is still alive in 2025. 👻

⚡ What’s Inside

Why your app still leaks memory (old + new culprits)
The usual suspects: static contexts, handlers, listeners
Modern traps: runaway coroutines, careless Flow collectors, Compose side-effects
A quick checklist to keep your RAM safe

🤯 A Quick Horror Story

Once, I tossed a coroutine into GlobalScope for a “quick fix.”

Weeks later, my app slowed down like it was running on a potato. 🥔

Turns out the coroutine was happily running long after the Activity was gone.

Lesson: leaks don’t scream on day one — they quietly rot your app.

✅ TL;DR Survival Checklist

Don’t store Activity/View in singletons
Use applicationContext for utilities
Use lifecycleScope / viewModelScope instead of GlobalScope
Collect flows with repeatOnLifecycle or collectAsStateWithLifecycle
Unregister listeners & receivers
Use Glide/Coil for images
Profile with LeakCanary + Memory Profiler
