Activity has been destroyed 的錯誤 (not use finish() -> System.exit(0); because onDetach bug)

    public void onEvent(FinishApp event) {
        FinishAppListener finishAppListener = new FinishAppListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                if (which == AlertDialogWhich.Y) {
                    try{
                        dialog.dismiss();

                        System.exit(0);////not use finish(); because onDetach bug
                    }catch (Exception e){
                        e.printStackTrace();
                    }

                }
            }
        };

        Utils.showAlertDialogYorN(this, getResources().getString(R.string.askExistApp), finishAppListener);
    }

在每個fragmnet加上

@Override
public void onDetach() {
    super.onDetach();

    try {
        Field childFragmentManager = Fragment.class.getDeclaredField("mChildFragmentManager");
        childFragmentManager.setAccessible(true);
        childFragmentManager.set(this, null);

    } catch (NoSuchFieldException e) {
        throw new RuntimeException(e);
    } catch (IllegalAccessException e) {
        throw new RuntimeException(e);
    }
}

不然的話你就會看到

Activity has been destroyed 的錯誤
