    1. COWhere did you actually expect the json data to appear? I don't see any interaction with your list view, have you included all your code? You need to set an adapter for the list view to "translate" your data into something that can be displayed on a list. For example, parse your JSONArray into a JSONObject[] and use an ArrayAdapter on your List view.

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).
