getActivity() returns null in Fragment function

Question

I have a fragment (F1) with a public method like this

public void asd() {
    if (getActivity() == null) {
        Log.d(\"yes\",\"it is null\");
    }
}
         


        

Answer 1

Another good solution would be using Android's LiveData with MVVM architecture. You would define a LiveData object inside your ViewModel and observe it in your fragment, and when LiveData value is changed, it would notify your observer (fragment in this case) only if your fragment is in active state, so it would be guaranteed that you would make your UI works and access the activity only when your fragment is in active state. This is one advantage that comes with LiveData

Of course when this question was first asked, there was no LiveData. I am leaving this answer here because as I see, there is still this problem and it could be helpful to someone.
