    <p>I'm trying to download multiple binary files using a Service which contains an AsynTask for doing background work. I'm able to run the Service successfully, I've registered it in the Manifest file. I'm able to download the files, however I would like to show a progress bar in the notification bar. I am creating the Notification bar inside the onPreExecute() method and setting the progressbar and notifying the NotifactionManager inside the onProgressUpdate() method.</p> <pre><code> private class DownloadFileAsync extends AsyncTask&lt;String, String, String&gt; { @Override protected void onPreExecute() { super.onPreExecute(); notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); notification = new Notification(R.drawable.icon, "Downloading...", System.currentTimeMillis()); contentView = new RemoteViews(getPackageName(), R.layout.progress_layout); contentView.setProgressBar(R.id.status_progress, 10, 0, false); contentView.setTextViewText(R.id.status_text,currentFile); notification.contentView = contentView; // Toast.makeText(DownloadService.this, "Downloading...!",Toast.LENGTH_SHORT).show(); } @Override protected String doInBackground(String... aurl) { int count; try { //Downloading code goes here } catch (Exception e) {} return null; } protected void onProgressUpdate(String... progress) { Log.d("ANDRO_ASYNC",progress[0]); notification.contentView.setProgressBar(R.id.status_progress, 100, Integer.parseInt(progress[0]), false); // inform the progress bar of updates in progress notificationManager.notify(NOTIFICATION_ID, notification); } @Override protected void onPostExecute(String unused) { Toast.makeText(DownloadService.this, "Download complete!",Toast.LENGTH_SHORT).show(); } } </code></pre> <p>The DownloadFileAsync private class is inside the DownloadService class which extends Service. I'm unable to show or update the notification bar. </p> <p>I'm currently getting an IllegalArgumentException on the line: notificationManager.notify(NOTIFICATION_ID, notification);</p> <p>Would really appreciate your help on this one!</p> <p>EDIT: NOTIFICATION_ID is defined as follows: private int NOTIFICATION_ID = R.string.app_name</p>

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.
