    <p>For what it's worth, I see a lot of errors from within the Android HTTP library. From Barcode Scanner I get stack traces from across about 35M people, and so I think I've seen one of everything. Here's all the weird stuff we just catch and swallow in the app, below. I recommend you work around it as a platform bug and fail gracefully.</p> <p><a href="https://code.google.com/p/zxing/source/browse/trunk/android/src/com/google/zxing/client/android/HttpHelper.java" rel="nofollow">https://code.google.com/p/zxing/source/browse/trunk/android/src/com/google/zxing/client/android/HttpHelper.java</a></p> <pre><code> private static int safelyConnect(String uri, HttpURLConnection connection) throws IOException { try { connection.connect(); } catch (NullPointerException npe) { // this is an Android bug: http://code.google.com/p/android/issues/detail?id=16895 Log.w(TAG, "Bad URI?

    1. COThere are many similar issues. I'm just suggesting that it is not something your app has done wrong. In that case there's not much to do except work around it gracefully.

    2. COI have different stack trace than code.google.com/p/android/issues/detail?id=15554 I think it is something to do with https connection or amazons host url. Also `openConnection()` call succeeds but `getInputStream()` fails

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).
