    <p>The problem is happening because you are trying to perform network operations on the UI thread.

    1. COThat's not a guaranteed answer to the question (depending on Android version, networking on the UI thread is allowed and the OP doesn't tell us which version he is using). It may well be correct at this stage but see my comment on the OP's question - he has a few other problems to fix.

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).
