    public static void startLoading(Context context, View root){
        if(null == contentView) contentView = root;
        if (loadingView == null) {
            loadingView = LayoutInflater.from(context).inflate(R.layout.view_loading, null, false);

            public void run() {
                startLoading(context, contentView);
            }
        });

    public static void hideLoadingInUiThread(Activity activity){
        activity.runOnUiThread(new Runnable() {
            @Override
            public void run() {
                hideLoading();
