if (stringData.matches("https://www.instagram.com/(.*)")) {
            String[] data = stringData.split(Pattern.quote("?"));
            String string = data[0];
            Log.i("TAG", "data: string "+string);
            if (isNetworkAvailable()) {
                Log.i("TAG", "data: isNetworkAvailable IF "+isNetworkAvailable());

                if (Method.isDownload) {

                    Log.i("TAG", "data: Method.isDownload IF "+Method.isDownload);

                    AsyncHttpClient client = new AsyncHttpClient();
                    client.get(string + "?__a=1", null, new AsyncHttpResponseHandler() {
                        @Override
                        public void onSuccess(int statusCode, Header[] headers, byte[] responseBody) {

                        }

                        @Override
                        public void onFailure(int statusCode, Header[] headers, byte[] responseBody, Throwable error) {
                            //Some thing went to wrong
                        }
                    });
                } else {
                    //First of all one download complete then after you can another download
                }
            } else {
              //No Internet Connection
            }
        } else {
            //No supported
