    <p>I'm seeing a StrictMode failure, and I can't see what's wrong with what I'm doing. The failure is:</p> <pre><code>java.lang.Throwable: Explicit termination method 'end' not called E/StrictMode(26875): at dalvik.system.CloseGuard.open(CloseGuard.java:184) E/StrictMode(26875): at java.util.zip.Inflater.&lt;init&gt;(Inflater.java:82) E/StrictMode(26875): at java.util.zip.GZIPInputStream.&lt;init&gt;(GZIPInputStream.java:96) E/StrictMode(26875): at java.util.zip.GZIPInputStream.&lt;init&gt;(GZIPInputStream.java:81) E/StrictMode(26875): at libcore.net.http.HttpEngine.initContentStream(HttpEngine.java:528) E/StrictMode(26875): at libcore.net.http.HttpEngine.readResponse(HttpEngine.java:836) E/StrictMode(26875): at libcore.net.http.HttpURLConnectionImpl.getResponse(HttpURLConnectionImpl.java:274) E/StrictMode(26875): at libcore.net.http.HttpURLConnectionImpl.getResponseCode(HttpURLConnectionImpl.java:486) E/StrictMode(26875): at com.mycompany.MyClass.sendJson(MyClass.java:267) </code></pre> <p>I configure StrictMode:</p> <pre><code>if (Build.VERSION.SDK_INT &gt;= Build.VERSION_CODES.HONEYCOMB) { StrictMode.setVmPolicy(new StrictMode.VmPolicy.Builder() .detectLeakedSqlLiteObjects().detectLeakedClosableObjects().penaltyLog() .penaltyDeath().build()); } </code></pre> <p>The code looks something like the following:</p> <pre><code>HttpURLConnection connection = null; OutputStream outputStream = null; InputStream in = null; try { connection = (HttpURLConnection)new URL("http://our.server/some/path").openConnection(); connection.setRequestProperty("Accept", "application/json"); connection .setRequestProperty("Content-Type", "application/json; charset=UTF-8"); connection.setDoOutput(true); outputStream = connection.getOutputStream(); String content = "{\"some\":\"json data\"}"; byte bytes[] = content.getBytes("UTF-8"); outputStream.write(bytes); outputStream.flush(); responseCode = connection.getResponseCode(); // This is line 267 in the stack trace if (HttpURLConnection.HTTP_OK == responseCode || HttpURLConnection.HTTP_CREATED == responseCode) { // do something with a successful response } } } catch (IOException e) { // report the exception } finally { if (null != connection) { connection.disconnect(); } if (null != outputStream) { try { outputStream.close(); } catch (IOException e) { } } if (null != in) { try { in.close(); } catch (IOException e) { } } } </code></pre> <p>I found somebody complaining of seeing the same StrictMode failure when using Google AdMob SDK (<a href="https://groups.google.com/forum/?fromgroups=#!topic/google-admob-ads-sdk/yVss4ufdPp4" rel="noreferrer">https://groups.google.com/forum/?fromgroups=#!topic/google-admob-ads-sdk/yVss4ufdPp4</a>) but I've not been able to find any solution so far.</p>

    1. COTried to (on gziped HTTP response), but can't reproduce the Exception. Are you setting an explicit [StrictMode policy](http://developer.android.com/reference/android/os/StrictMode.html)? What's your Android SDK version?

    3. CODid you ever find a solution to this? To me it looks like a bug in Android's GZIPInputStream, since it creates an Inflater, registers a close guard for "end", but then never actually calls end.

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).
