    <p>I am using a object I created in my android object to send values as json to my php web service. the sending works well. But after the send I am expected to collect the object back from the web service based on my design which I would now test to be sure that there was a successful post. But I get a funny message in my Log cat as an exception through in my catch statement. I just believe that it as to do with how I am compressing json from my php webservice to android java code.</p> <p>Exception below <strong>Default buffer size used in BufferedReader constructor. It would be better to be explicit if an 8k-char buffer is required.</strong></p> <p>JSON OUTPUT 11-15 07:48:02.622: I/global(276): Default buffer size used in BufferedReader constructor.

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).
