LeakCanary appears to detect a leak, even though the class is excluded

2.3k views Asked by At

I'm slightly confused by the behavior of LeakCanary, and I'm hoping SO can help me out here. I've added LeakCanary to my app, and I'm seeing a pop-up claiming a leak.

This sure looks like the InputMethodManager mentioned here: https://github.com/square/leakcanary/issues/322

It looks like LeakCanary marks it as excluded, but still shows the popup. Is there something I'm not understanding here? (I can include my exclude code if that helps, but...)

Here's a screenshot of the Leak activity:

I had this tree with excluded leak:

AudioManager.mContext_static (excluded)
|
ContextImpl.mOuterContext
|
MyAudioActivity

Under the first element it shows info:

Excluded by rule AUDIO_MANAGER__MCONTEXT_STATIC ...
... because Samsung added a static mContext_static field to AudioManager, holds a reference to the activity

Then in the LeakCanary FAQ I found this page:

https://github.com/square/leakcanary/wiki/FAQ#can-a-leak-be-caused-by-the-android-sdk

Which explains that some leaks cannot be fixed by the developer. It points to the AndroidExcludedRefs.java file which has the mentioned AUDIO_MANAGER__MCONTEXT_STATIC entry.

I hope you have already got the reason, but for anyone else reading this post in future, the reason I think for showing excluded and known leak is :-

  • to notify you that something bad but known is happening and
  • to show you the hack/fix/track available to avoid this leak.

It seems that LeakCanary intentionally show the notification because removing them is bad behavior for some users and they are looking into making this clearer.

Clarify what "excluded leaks" are about:

Initially we were hidden the excluded leaks but then people would complain that they'd see the VM freeze and couldn't find the leak afterwards.
