    1. COThe exception suggests that something is null in your getView method at the line number 41. Can you post the code on the line 41? Most probably some of the textviews is not found in the convertView. You are calling your Adapter with the `android.R.layout.simple_list_item_1` layout, you probably want to replace this with your custom layout.

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).
