    1. COWe are seeing the same, but all the time. It happens randomly and when it occurs we need to open a new HTTP connection to the server. Could the problem be introduced in one of the latest Android versions 2.2 or 2.3. We have not seen any issue on real devices. Which version are you using? Have you tested on a real device?

    2. COI am using android 2.1. I don't have any problem with real devices. It is working fine for me because I am compiling server (which is in C) with arm complier that android uses for comping C apps.(If you check ndk documentation).

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).
