Android Fragment no view found for ID?
I was having this problem too, until I realized that I had specified the wrong layout in setContentView() of the onCreate() method of the FragmentActivity.
The id passed into FragmentTransaction.add(), in your case R.id.feedContentContainer, must be a child of the layout specified in setContentView().
You didn't show us your onCreate() method, so perhaps this is the same problem.
This error also occurs when having nested Fragments and adding them with getSupportFragmentManager() instead of getChildFragmentManager().
The solution was to use getChildFragmentManager()
instead of getFragmentManager()
when calling from a fragment. If you are calling the method from an activity, then use getFragmentManager().
That will solve the problem.
