    <p>I have an inner class that downloads some images from the server. The problem is that the ProgressDialog does not dismiss() onPostExecute() method and don't understand why. I understand that the progress dialog should be shown onPreExecute() method, and the after the code from the doInBackground() finished , in the onPostExecute() method the dialog should be dismiss. Do you have any idea what i am doing wrong here? Thank you.</p> <pre><code> /** * Download images from server */ public class DownloadAsyncTask extends AsyncTask&lt;Void, Integer, Void&gt; { private ProgressDialog mDialog; // execution of result of Long time consuming operation protected void onPostExecute(Void result) { // progressDialog.show(); if (mDialog.isShowing()) { mDialog.dismiss(); } } // Things to be done before execution of long running operation. protected void onPreExecute() { mDialog = ProgressDialog .show(ImagesActivity.this, getString(R.string.pleasewait), getString(R.string.loading)); } // perform long running operation operation protected Void doInBackground(Void... params) { System.out.println("doInBackground loading.." + id); String tempPath = FileUtils.createTempFile(id); for (int i = 0; i &lt; imagePaths.size(); i++) { imagePaths.get(i).trim(); try { Bitmap imgTemp; imgTemp = FileUtils.downloadBitmapFromURL(id, imagePaths.get(i), tempPath); System.out.println("imgTemp: " + imgTemp); if (imgTemp != null) { // save image on sdcard. // compress it for performance Bitmap img = Bitmap.createScaledBitmap(imgTemp, 90, 80, true); imgTemp.recycle(); FileUtils.saveDataToFile(img, tempPath, imagePaths.get(i)); } else { continue; } } catch (IOException e) { e.printStackTrace(); mDialog.dismiss(); } } Looper.prepare(); mDialog.dismiss(); return null; } /* * Things to be done while execution of long running operation is in * progress. */ protected void onProgressUpdate(Integer... values) { if (mDialog.isShowing()) { mDialog.dismiss(); } } } </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).
