    1. COIt's not clear what you're asking here. Are you getting an error? What's happening when you run your application? Have you tried stepping through with a debugger, and if so, what are you expecting to see and where is your application departing from that?

    2. COI think you need to repeat text_search.setAdapter(adapter); when you update your adapter. Repeat it at the end of onPostExecutr

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).
