0 LIBRARY LEAKS

A Library Leak is a leak caused by a known bug in 3rd party code that you do not have control over. See https://square.github. io/leakcanary/fundamentals-how-leakcanary-works/#4-categorizing-leaks

0 UNREACHABLE OBJECTS

An unreachable object is still in memory but LeakCanary could not find a strong reference path from GC roots.
