    <p>I create a notification from my custom layout with a progress bar. When the task is finished I make the progress bar invisible, this is working fine with Android 2.3.3 and newer versions. In older version, whole notification becomes invisible, no icon, no text, no nothing, but the "Clear" button becomes activated which means there is a notification.</p> <p>How I created the notification and updated using <code>NotificationCompat</code> from Android Support Library;</p> <p>Following variables are declared in AsyncTask class as private members;</p> <pre><code>private NotificationCompat.Builder nBuilder; private RemoteViews contentView; private Notification n; private int nId; //Notification ID </code></pre> <p>AsyncTask Functions;</p> <p>When download start</p> <pre><code>protected void onPreExecute() { super.onPreExecute(); contentView = new RemoteViews(getPackageName(), R.layout.custom_notification); contentView.setTextViewText(R.id.notification_title, nTitle); contentView.setProgressBar(R.id.notification_progressbar, 100, 0, false); contentView.setImageViewResource(R.id.notification_image, R.drawable.ic_launcher); contentView.setTextViewText( R.id.notification_progresstext, "" + df.format(total) + " MB / " + df.format((float) fileLength) + " MB"); nBuilder = new NotificationCompat.Builder(getApplicationContext()); nBuilder.setSmallIcon(R.drawable.ic_launcher) .setWhen(System.currentTimeMillis()).setTicker(mp3Name); if (Build.VERSION.SDK_INT &gt;= 11) { // sets FLAG_ONGOING_EVENT nBuilder.setOngoing(true).setContent(contentView) .setAutoCancel(false); n = nBuilder.build(); } else { // required, otherwise will crash with an IllegalArgException Intent intent = new Intent(getApplicationContext(), MainActivity.class); intent.addFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT); PendingIntent pend = PendingIntent.getActivity( getApplicationContext(), 0, intent, PendingIntent.FLAG_UPDATE_CURRENT); nBuilder.setContentIntent(pend); n = nBuilder.build(); n.contentView = contentView; // since flags are ignored in earlier version set them directly n.flags = Notification.FLAG_ONGOING_EVENT | Notification.FLAG_NO_CLEAR; } nManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE); nManager.notify(nId, n); Toast.makeText(getApplicationContext(), R.string.download_started, Toast.LENGTH_LONG).show(); } </code></pre> <p>On progress update</p> <pre><code>protected void onProgressUpdate(Integer... progress) { super.onProgressUpdate(progress); if (progress[0] != currentProgress) { if (progress[0] &gt;= 100) { // PROGRESS 100 nManager.cancel(nId); nBuilder = new NotificationCompat.Builder( getApplicationContext()); nBuilder.setSmallIcon(R.drawable.ic_launcher) .setWhen(System.currentTimeMillis()) .setTicker(mp3Name); contentView.setProgressBar(R.id.notification_progressbar, 100, progress[0], false); contentView.setTextViewText( R.id.notification_progresstext, "" + df.format(total / 1048576f) + " MB / " + df.format(fileLength / 1048576f) + " MB"); contentView.setViewVisibility( R.id.notification_progressbar, View.GONE); Intent intent = new Intent( android.content.Intent.ACTION_VIEW); intent.setDataAndType(Uri.parse("file://" + fullFilePath), "audio/mpeg"); intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK); PendingIntent pi = PendingIntent.getActivity( getApplicationContext(), 0, intent, PendingIntent.FLAG_UPDATE_CURRENT); nBuilder.setContentIntent(pi); if (Build.VERSION.SDK_INT &gt;= 11) { nBuilder.setOngoing(false).setContent(contentView) .setAutoCancel(true); n = nBuilder.build(); } else { n = nBuilder.build(); n.contentView = contentView; n.flags = Notification.FLAG_AUTO_CANCEL; } nManager.notify(nId, n); } else { // PROGRESS &lt; 100 contentView.setProgressBar(R.id.notification_progressbar, 100, progress[0], false); contentView.setTextViewText( R.id.notification_progresstext, "" + df.format(total / 1048576f) + " MB / " + df.format(fileLength / 1048576f) + " MB"); if (Build.VERSION.SDK_INT &gt;= 11) { nBuilder.setContent(contentView); n = nBuilder.build(); } else { n = nBuilder.build(); n.contentView = contentView; } nManager.notify(nId, n); } // nManager.notify(nId, n); currentProgress = progress[0]; } } </code></pre> <p>I have to remove <code>contentView.setViewVisibility(R.id.notification_progressbar, View.GONE);</code>, then it looks ugly.</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.

SQuiL has stopped working due to an internal error.

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