Defining layout dimensions with pixels is a problem because different screens have different pixel densities, so the same number of pixels may correspond to different physical sizes on different devices. Therefore, when specifying dimensions, always use either dp or sp units. A dp is a density-independent pixel that corresponds to the physical size of a pixel at 160 dpi. An sp is the same base unit, but is scaled by the user's preferred text size (it’s a scale-independent pixel), so you should use this measurement unit when defining text size (but never for layout sizes).</p> <p>For example, when you specify spacing between two views, use dp rather than px:</p> </blockquote> <pre><code> &lt;Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/clickme" android:layout_marginTop="20dp" /&gt; </code></pre>

    1. COWhat I mean is if I abstract the screen to width 320, then 0 dp would be the extreme left and 320 would be the extreme right. Porting an existing app would be simple(r) instead of going back to design phase/table.

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).
