InstagramActivity is First Activity which will visible to user after splashscreen. GetDataFromServer is a singleton which i use for network call using retrofit.

I couldn't understand mLoadedApk and mReceivers mentioned in the leakcanary logs. As there is no reference variable I have declared in my code.

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.

====================================
0 UNREACHABLE OBJECTS

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

  • Please share the code snippets to understand this better way – Raj Suvariya Nov 10 '21 at 09:00
  • Please provide enough code so others can better understand or reproduce the problem. – Community Nov 11 '21 at 03:31
  • Thanks Here is the solution. mLoadedApk is linked with Boradcast receiver which needs to be deregistered before destroying activity/view. Which i didn't do previously. https://stackoverflow.com/questions/66611127/leakcanary-not-giving-enough-information-to-identify-leak – Roshan Kumar Nayak. Nov 11 '21 at 07:47
