Android - Getsupportfragmentmanager() Returning Null

I know there are a lot of similar questions here, but none of them have worked for me so far, so I'm hoping by just posting my (slightly redacted) class here, someone can help me o

Solution 1:

I was having the same problem.

What I deduce it about the lifecycle of the activity, in the method onCreate the activity isn't totally created so when you try to pass getSupportFragmentManager its null.

What I do to resolve it, is putting this lines of code in onStart. The problem there is that each time the activity is paused and run it again the Fragment will be restarting.
