すべてのファイルをダウンロードしています。私がしたことは for ループでした。残念ながら、私の for ループは非同期タスクを終了せず、ダウンロード中の最初のファイルを終了したかどうかに関係なく、すべてのループを実行し続けます。助けてください。

これが私のforループです

for (int i = 0; i < id.length; i++) {
            Element e = (Element)nodes.item(i);
            id[i] = ""+CategoriesXMLfunctions.getValue(e, "id");
            name[i] = ""+CategoriesXMLfunctions.getValue(e, "name");
            image[i] = ""+CategoriesXMLfunctions.getValue(e, "image");
            simage[i] = ""+CategoriesXMLfunctions.getValue(e, "simage");
            download[i] = ""+CategoriesXMLfunctions.getValue(e, "download");
            author[i] = ""+CategoriesXMLfunctions.getValue(e, "author");

そして、ここに私の非同期タスクがあります

            super.onPreExecute();
            //showDialog(DIALOG_DOWNLOAD_PROGRESS);
        }

        @Override

            try {

                URL u = new URL(fileURL);

                String PATH = getDir("ebook", MODE_PRIVATE).toString();

                while ((len1 = in.read(buffer)) > 0) {
                    total += len1; //total = total + len1
                    //publishProgress("" + (int)((total*100)/lenghtOfFilee));
                    fos.write(buffer, 0, len1);
                }
                fos.close();
            } catch (Exception e) {
               // Log.d("Downloader", e.getMessage());
            }

            return null;

        }

        protected void onProgressUpdate(String... progress) {
            // Log.d("ANDRO_ASYNC",progress[0]);
             //mProgressDialog.setProgress(Integer.parseInt(progress[0]));
        }

        @Override

            checkdownloadall();
            //dismissDialog(DIALOG_DOWNLOAD_PROGRESS);
        }

    }
