    <p>The <code>Loader</code> documentation is flawed.</p> <p>100% of <code>Loader</code> implementations built into Android itself "monitor the source of their data and deliver new results when the contents change". Since there is only one <code>Loader</code> implementation built into Android itself as of now, their documentation is accurate as far as that goes.</p> <p>However, quoting a book update of mine that should be released in an hour or two:</p> <blockquote> <p>There is nothing in the framework that requires this behavior. Moreover, there are some cases where is clearly a bad idea to do this – imagine a Loader loading data off of the Internet, needing to constantly poll some server to look for changes.</p> </blockquote> <p>I do plan on augmenting <code>SQLiteCursorLoader</code> to be at least a bit more aware of database changes, if you route all database modifications through it. That too will have limitations, because you don't share <code>Loader</code> objects between activities (let alone have access to them from services).</p> <p>The only reason <code>CursorLoader</code> works as it does is because it uses a <code>ContentProvider</code> -- a singleton that can therefore be aware of all operations.</p> <p>At the moment, whatever portion of your code is responsible for inserts, updates, and deletes will either need to tap the <code>SQLiteCursorLoader</code> on the shoulder and have it update, or notify the activity of the change (e.g., broadcast from a <code>Service</code>) so the activity can tap the <code>SQLiteCursorLoader</code> on the shoulder.</p>

    1. COI've been going through the Loader source code all day and have been beginning to suspect as much. Thanks.

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).
