Android Fragment no view found for ID?

Question

I have a fragment I am trying to add into a view.

FragmentManager fragMgr=getSupportFragmentManager();
feed_parser_activity content = (feed_parser_activity)f         


        

Answer 1

Sometimes it is because you are using a BottomNavigationView. If you open an Intent from the navigation and in that activity you open a fragment lets say

transaction.replace(R.id.container,new YourFragment());

then the Activity won't be able to find the navigation method you are using.

SOLUTION: Change the activity to fragment and handle navigation with addOnBackStack in your app. If you've implemented the Jetpack Navigation just use fragments in your project.
