    1. COworks great, but super.onTouch(view, motionEvent); gives me error warning in eclipse "is undefinied for the type object". Deleting this works great.

    2. COThanks works like a charm but you should add a constructor to `OnSwipeTouchListener` that receives a context because that constructor of `GestureDetector` is deprecated since API level 3, and instantiate the `GestureDetector`in that constructor.

Guidance
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).
