    2. COif u are actually between the two activities ... on which VIEWGROUP do you think your progress bar will appear??? The progreeBar is hanged because the UI is blocked! I dont think you can show ProgressBar between two activities... (after onDestroy of 1st and before onCreate of second)

    3. CO@Aditya Nikhade Your statement makes sense, but - as I understand it AsincTask allows separate display of dialogue from the activity itself (maybe I'm wrong.) I do not understand how you can implement in printsygt conceived by me - I've tried to allocate for this purpose a separate thread and execute code that should fire when you press the button - but it gave cover those results.

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).
