How to dismiss a DialogFragment when pressing outside the dialog?

Lot of answers here but, the app crash when dialog opens. Writing getDialog().setCanceledOnTouchOutside(true); inside onCreateView did not work and crashed my app.

(I am using AppCompatActivity as my BaseActivity and android.app.DialogFragment as my Fragment).

What works is either of the two following lines:

getDialog().setCanceledOnTouchOutside(true);

OR

this.getDialog().setCanceledOnTouchOutside(true);

inside onActivityCreated like

@Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
        //getDialog().getWindow().getAttributes().windowAnimations = R.style.DialogAnimationZoom;
        //getDialog().getWindow().setDimAmount(0.85f);
        getDialog().setCanceledOnTouchOutside(true);//See here is the code
    }

What not to use:

DialogFragment.getDialog().setCanceledOnTouchOutside(false);

throws following error

And writing the code in onCreateView crashes the App! Please update the answer if you find something wrong.

DialogFragment.getDialog().setCanceledOnTouchOutside(true);

Must be called in onCreateView (as Apurv Gupta pointed out).

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
       ...
       getDialog().setCanceledOnTouchOutside(true);
       ... 
       }

    /** The system calls this only when creating the layout in a dialog. */
    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        // The only reason you might override this method when using onCreateView() is
        // to modify any dialog characteristics. For example, the dialog includes a
        // title by default, but your custom layout might not need it. So here you can
        // remove the dialog title, but you must call the superclass to get the Dialog.
        Dialog dialog = super.onCreateDialog(savedInstanceState);
        dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        dialog.setCanceledOnTouchOutside(true);

        return dialog;
    }
