AndroidRuntimeException: requestFeature() must be called before adding content

[johnjohndoe]

I replaced android.support.v4.app.DialogFragment with SimpleDialogFragment:

public class MyDialogFragment extends SimpleDialogFragment {
    @NonNull
    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        FragmentActivity activity = getActivity();
        View contentView = activity.getLayoutInflater()
                .inflate(R.layout.fragment_my_dialog, null)
        AlertDialog.Builder dialogBuilder = new AlertDialog.Builder(activity);
        dialogBuilder
                .setView(contentView)
        return dialogBuilder.create();
    }

It is called here within a parent fragment:

DialogFragment dialogFragment = new MyDialogFragment();
dialogFragment.show(getActivity().getSupportFragmentManager(),
        MyDialogFragment.FRAGMENT_TAG);

The following error occurs when I open the dialog:

Hi,
what are you trying to do? Just display a custom content in the dialog?
Have a look to JayneHatDialogFragment in demo app - you should override method build(), not onCreateDialog()

[johnjohndoe]

Sorry, but I did not see this from the README. Maybe you want to mention it there more explicit.

[davidvavra]

It's in the readme, see section "How to create all other DialogFragments:". Would you phrase it differently?

[johnjohndoe]

I thought others might also stumble into the error since onCreateDialog() is the common way. Therefore, it might be helpful to explicitly name the build() method already in the README. Also a speaking error message would be nice if one uses onCreateDialog() and should not do so.
