    2. COActually, I don't even need logcat to see what is wrong (but you should definitely use it all the time to see what is going on with your app). You are making network operations in your Activity. Activities are here to manage the UI of your app. Your terminal is probably running Android 3.0 or superior. With this version an error has been added to prevent devs from making networks operations in the UI thread. Each time you do this, your UI freeze until you get the answer. All heavy operations must not be made in the UI thread. Asynctask is an elegant solution to this problem

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).
