LeakActivity Leaked showing on Leak Canary

This activity is not part of my app and it keeps showing on Leak Canary app.

it doesnt even seems related to what activity i run and if i opened the app at all.

i got this message total of 6 times during last 12 hours

Can someone help to understand it?

This is a know leak in the Android framework (ViewGroup.ViewLocationHolder) : https://github.com/square/leakcanary/issues/1081

LeakCanary actually identifies it as such, which is why it's reported as a "LibraryLeak". See that thread for ways to maybe fix it (it's hard because it's a bug in the android framework).
