    <p>In my application I want to be able to play streaming video (by way of RTSP protocol). I found open RTSP stream: <code>rtsp://red7blue.de/Primetime</code> and tried to play it. But my application is being terminated by signal SIGILL while trying to play video. I'm using libffmpeg.so and cause ofthe SIGILL signal is located in the code of this library. Look at what I got in logs:</p> <pre><code>D/dalvikvm( 217): Trying to load lib /data/data/my.apps.package/lib/libffmpeg.so 0x43757d68 D/dalvikvm( 217): Added shared lib

RTSP is a network protocol. It's meaning that ffmpeg.so tries to access media stream using network. Maybe some special permissions should be specified for that? In my app I have the only explicit permission - <code>android.permission.INTERNET</code> Should I specify something else?</p>

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).
