I was thinking about shared preferences but how would I know that the dialog was being shown before the activity got destroyed and now that the user is coming back into the app, I have to show the dialog. I have also heard that simply calling alertDialog.show() will not work after the activity has been destroyed. What can I do? Thank you.</p>

    1. COYou are right, add in `onDestroy()` method some info to shared preferences. After on load Activity extract that info from.

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.
