Android Snackbar NullPointerException in Fragment

I want to add a basic snackbar to my application but i have received an error that i couldn't figure out why.

I added this code in the onCreateView() method in my Fragment.

Snackbar.make(view, "Snackbar", Snackbar.LENGTH_LONG)
.setAction("Action", null).show();

And received this error:

If your Fragment is added to existing activity(Remember you can add it through xml), you should call the SnackBar's method into the onActivityCreated() method of the Fragment.

public void onActivityCreated(Bundle savedInstanceState) {
    Snackbar.make(view, "Snackbar", Snackbar.LENGTH_LONG)
        .setAction("Action", null).show();
