Debugging Android OOM Crashes: A Case Study of Memory Leak in Coil Image Loader
The article narrates how a developer diagnosed and resolved an Android OOM crash caused by a memory leak in the Coil image loading library, using Android Studio Profiler to trace native bitmap allocations and applying a library fix to prevent view‑detach related leaks.
A sudden surge of OOM crashes prompts the developer Xiao Wang to investigate the Android app's memory usage.
Opening Android Studio's Profiler, he observes that while Java heap growth is modest, native memory spikes dramatically, indicating a potential bitmap‑related issue on Android 10 where bitmap pixel data resides in native heap.
Using the Profiler's dump and reference‑chain view, he discovers that the Coil library's memory cache retains bitmap objects via a detached view, leading to a substantial native memory leak.
He locates a pull request (PR #518) that fixes this leak, upgrades the Coil dependency, and confirms that the OOM crashes disappear.
The root cause is identified as loading images after a view has been detached; Coil stores the view reference, preventing bitmap release. The solution is to check the view's detach state before initiating image requests.
After applying the fix, the app runs without memory leaks, and the developer celebrates the successful resolution.
