    <p>I'm trying to make a simple app that records sound as long as the button is pressed and then saves the recorded file to a certain location. This is the code I've got so far and it crashes as soon as I touch the imagebutton:</p> <pre><code>package com.whizzappseasyvoicenotepad; import java.io.File; import java.io.IOException; import

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.
