    <p>I am trying to download several text files from a server. They all have similar names (e.g text1.txt, txt2.txt) but different numbers (changing quantities every month). I can't seem to download the files. Java keeps telling me that it is encountering a file not found error/exception. Does anyone know how I can get past this?</p> <p>The download class.</p> <pre><code> public class downloadText extends AsyncTask&lt;String, String, String&gt; { @Override protected void onPreExecute() { super.onPreExecute(); showDialog(DIALOG_DOWNLOAD_PROGRESS); } @Override protected String doInBackground(String... params) { try { File sourceLocation = new File(targetPath); sources = sourceLocation.listFiles(); Arrays.sort(sources); File root = android.os.Environment .getExternalStorageDirectory(); File dir = new File(root.getAbsolutePath() + "aiyo/edition/text/"); if (dir.exists() == false) { dir.mkdirs(); } Log.d("param", params[0]); URL url = new URL("http://create.aiyomag.com/assets/app_mag/ALYO/9_1342080926/text"); // you can write here any link URLConnection connection = url.openConnection(); connection.connect(); int contentLength=connection.getContentLength(); // get file name and file extension String fileExtenstion = MimeTypeMap .getFileExtensionFromUrl(params[0]); String name = URLUtil.guessFileName(params[0], null, fileExtenstion); File file = new File(dir, name); Log.d("File in content","The file is "+file.getName()); /* * Define InputStreams to read from the URLConnection. */ InputStream is = connection.getInputStream(); BufferedInputStream bis = new BufferedInputStream(is); OutputStream fos = new FileOutputStream(file); /* * Read bytes to the Buffer until there is nothing more to * read(-1). */ int lenghtOfFile = connection.getContentLength(); int total = 0; byte baf[] = new byte[1024]; int current = 0; while ((current = bis.read(baf)) != -1) { total += current; // publishProgress("" + (int) ((total * 100) / // lenghtOfFile)); mProgressDialog.setProgress(((total * 100) / lenghtOfFile)); fos.write(baf, 0, current); } // close every file stream fos.flush(); fos.close(); is.close(); } catch (IOException e) { Log.e("DownloadManager", "Error: " + e); } return null; } @Override protected void onProgressUpdate(String... values) { mProgressDialog.setProgress(Integer.parseInt(values[0])); } @Override protected void onPostExecute(String result) { // TODO Auto-generated method stub // if (fileInteger == max) { // dismissDialog(DIALOG_DOWNLOAD_PROGRESS); // return; // } Log.d("post execute", "i::" + fileInteger); // fileInteger++; // publishProgress("" + (int) ((fileInteger * 100) / max)); // mProgressDialog.setSecondaryProgress(((fileInteger * 100) / max)); String link = txturl; downloadText = new downloadText(); downloadText.execute(link); } </code></pre> <p>The main.</p> <pre><code> btn_txt = (Button) findViewById(R.id.text); btn_txt.setOnClickListener(new OnClickListener() { public void onClick(View v) { // TODO Auto-generated method stub String link; link = txturl+fileInteger+".txt"; new Thread(new Runnable() { public void run() { max = (totalFile(pageNum) - 1); text.post(new Runnable() { public void run() { text.setText("" + max); } }); } }).start(); downloadText = new downloadText(); downloadText.execute(link); } }); </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
