    1. COAlways paste all relevant LogCat output for any error you want help with. Some people may be able to find out what is wrong by eyeballing your code but it is a lot easier to just read your error log (which specifically tells you what is wrong). This can be viewed in the "LogCat" view in Eclipse.

    2. COThanks, check out gopal's answer. You are calling UI methods (setimageresource) from a non-UI thread. "Only the original thread that created a view hierarchy can touch its views"

    3. COOK thanks. I read it. The big problem is that I don't understand this AsyncTask very good. There are only examples with downloading the pics, what doesn't need for me. Thanks

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).
