LeakCanary - A memory leak detection library for Android and Java

LeakCanary is a memory leak detection library for Android. LeakCanary’s knowledge of the internals of the Android Framework gives it a unique ability to narrow down the cause of each leak, helping developers dramatically reduce OutOfMemoryError crashes.

In a Java based runtime, a memory leak is a programming error that causes an application to keep a reference to an object that is no longer needed. As a result, the memory allocated for that object cannot be reclaimed, eventually leading to an OutOfMemoryError (OOM) crash.

For example, an Android Activity instance is no longer needed after its onDestroy() method is called, and storing a reference to that instance in a static field prevents it from being garbage collected. LeakCanary will help you find and fix these memory leaks during development.
