    1. COWhat do you mean by "get in the fragment a second time"? What are you doing that might be destroying the activity? i.e. going to another activity and backing up to this one again, going to the home screen or a phone call and then returning to this activity, etc.

    3. COSorry, ignore my first answer about the singleton. I was confused a bit because you aren't following standard Java naming conventions in your newInstance method. Your classname doesn't start with a capital letter, and your local variable started with a lower-case m, which usually is reserved for member variables.

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).
