I have this log file in my crash reporter dashboard:

Fatal Exception: java.lang.NullPointerException: Attempt to invoke virtual method 'boolean android.support.v4.widget.DrawerLayout.b()' on a null object reference
       at examplecompany.video.BottomNavActivity$1.onClick(Unknown Source)
       ...

Based on this answer, $1 refers to an inner class. But in my BottomNavActivity I have no inner class. Also I can't find onClick method in that class. How do I interpret this to find out the problem?

Update: I have a bunch of setOnClickListener calls in my code. If it relates to those calls, how do I know which call is the root of the problem, and also why onClick is in log file. Why setOnClickListener is not logged?

how about showing some code? probably, you implement ClickListener or the like (or wrote code that expects your class to) – Stultuske Nov 12 '18 at 08:19
Presumably it's an anonymous implementation of `OnClickListener`. – Michael Nov 12 '18 at 08:19
Yeah, I have a bunch of `setOnClickListener` calls. But which one? Also why `onClick`? I don't understand that part. – mohammad rostami siahgeli Nov 12 '18 at 08:20
i believe u dont have `BottomNavActivity$1` id in your xml layout – Donald Wu Nov 12 '18 at 08:20
_"Also why onClick?"_ Because each `OnClickListener` implements `onClick`. – Michael Nov 12 '18 at 08:25
