    <p>I am trying to download a file from a URL. If the download fails (regardless of the reason) I want the application to retry an hour later.</p> <p>Since the download is in it's own thread (not the main thread), I can't seem to start a new CountDownTimer. </p> <p>I don't want to block the download thread so I'm trying to use the CountDownTimer.</p> <p>Is there another way to do this?</p> <p>Thanks in advance!</p> <pre><code>private class Downloader extends AsyncTask&lt;Object, Void, File&gt; { @Override protected File doInBackground(Object... params) { Context context = (Context) params[0]; String strUrl = (String) params[1]; String strFileName = (String) params[2]; return download(context, strUrl, strFileName); } /** * Downloads files in a separate thread.

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.
