    <p>I've worked on an Android app in the past where the java developer set it to alert JavaScript errors - caught an extra bug that we didn't catch in the iOS version because of it. So, if you have access to the java layer, I'd check that out. I asked him what he did specifically and he said: "There's a callback from the WebView class that lets me know when the JS code throws an error. I implemented that callback to display an android dialog."</p> <p>There's two solutions other ideas on top of this that I use for debugging (ios/android). These are especially useful for embedded web views in games where you don't have access to the built-in console:</p> <p>1) <a href="http://people.apache.org/~pmuellr/weinre/docs/latest/" rel="noreferrer">Weinre</a> a still beta, but functional, remote debugger. It'll give you a faux inspector on your desktop that you can query / see errors on your remote device with. Has a whole dom inspector and anything. The guy that develops it is pretty responsive, too.</p> <p>2) I write a javascript log function that hits my servers error log. Just tail your log file and you're good to go. My javascript function looks something like this:</p> <pre><code>function hlog(){ var s = Array.prototype.slice.apply(arguments).join('¶'); document.createElement('img').src = 'http://yourdevbox/debugger/?m=' + encodeURIComponent(s); } </code></pre> <p>That way I can take any number of arguments. My php page that recieves this request looks like this:</p> <pre><code># ensure this can't be used in production if (strpos($GLOBALS['HTTP_HOST'], 'devboxhostname') &lt; 0) die(':('); error_log($_GET['m']); </code></pre> <p>Hopefully in the future, mobile devs will have way better debugging tools.</p>

    2. COGreat answer. I've started using weinre, and it's useful, but doesn't seem to print any javascript errors to the console. I'm developing using phonegap, if that makes a difference. Any advice?

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).
