它适用于模拟器和真实设备（Android版本4），但它不适用于真实设备（android version7.0）

相关代码： ```

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

    View view = inflater.inflate(R.layout.fragment_card_action, container);
    application = (LaftelApplication) getActivity().getApplication();
    userId = application.getUserInfo().id;

    ratingBar = (RatingBar) view.findViewById(R.id.rating_bar);
    ImageView btnDeleteRating = (ImageView) view.findViewById(R.id.btn_delete_rating);
    btnSubscribe = (CheckableLinearLayout) view.findViewById(R.id.btn_subscribe);
    btnWish = (CheckableLinearLayout) view.findViewById(R.id.wish_item);
    btnRecommend = (CheckableLinearLayout) view.findViewById(R.id.btn_recommend);
    btnBanRecommend = (CheckableLinearLayout) view.findViewById(R.id.ban_recommend);

    mContext = getContext();
    getDialog().getWindow().requestFeature(Window.FEATURE_NO_TITLE);
    mItem = (Item) getArguments().getSerializable("item");





    ImageView itemTypeView = (ImageView) view.findViewById(R.id.item_type);
    if (mItem.type.equals(Constants.DB_ITEM_TYPE_ANIMATION)) {
        itemTypeView.setImageResource(R.drawable.label_ani_round);

    } else if (mItem.type.equals(Constants.DB_ITEM_TYPE_LIGHTNOVEL)) {
        itemTypeView.setImageResource(R.drawable.label_lnovel_round);
    }

    TextView itemNameView = (TextView) view.findViewById(R.id.item_name);
    itemNameView.setText(mItem.name);

    // CardAction Setting
    Call<RatingList> userPreferenceCall = application.service.getUserPreference(userId);
    userPreferenceCall.enqueue(new Callback<RatingList>() {
        @Override
        public void onResponse(Call<RatingList> call, Response<RatingList> response) {
            userRating = response.body();
            setUserPreferences();
        }

        @Override
        public void onFailure(Call<RatingList> call, Throwable t) {
        }
    });

    Call<SubscriptionList> userSubcriptionCall = application.service.getUserSubcriptionSet("application/json", userId);
    userSubcriptionCall.enqueue(new Callback<SubscriptionList>() {

            userSubcriptionInfo = response.body();
            setUserSusbscription();
        }

        @Override
        public void onFailure(Call<SubscriptionList> call, Throwable t) {

Answer 1

将application = (LaftelApplication) getActivity().getApplication();从onCreateView移至onActivityCreated

@Override
public void onActivityCreated(@Nullable Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);
    application = (LaftelApplication) getActivity().getApplication();
}

Android App适用于模拟器，但不适用于真实设备
