Example: I start app with Activity A > then goes to activity B> then activity C now I put my app in background and come and then I comeback to foreground the C activity automatically gets close it shows activity B. please help me its a big project I am working on existing code. I don't know what property has been set there. I have checked onPause() and onResume() methods everywhere in the app nothing is there that can close the activity.
