    copied!<p>I seem to be running into a peculiar problem on Android 1.5 when a library I'm using (signpost 1.1-SNAPSHOT), makes two consecutive connections to a remote server. The second connection always fails with a <code>HttpURLConnection.getResponseCode()</code> of <code>-1</code></p> <p>Here's a testcase that exposes the problem:</p> <pre><code>// BROKEN public void testDefaultOAuthConsumerAndroidBug() throws Exception { for (int i = 0; i &lt; 2; ++i) { final HttpURLConnection c = (HttpURLConnection) new URL("https://api.tripit.com/oauth/request_token").openConnection(); final DefaultOAuthConsumer consumer = new DefaultOAuthConsumer(api_key, api_secret, SignatureMethod.HMAC_SHA1); consumer.sign(c); // This line... final InputStream is = c.getInputStream(); while( is.read() &gt;= 0 ) ; // ... in combination with this line causes responseCode -1 for i==1 when using api.tripit.com but not mail.google.com assertTrue(c.getResponseCode() &gt; 0); } } </code></pre> <p>Basically, if I sign the request and then consume the entire input stream, the next request will fail with a resultcode of -1. The failure doesn't seem to happen if I just read one character from the input stream.</p> <p>Note that this doesn't happen for any url -- just specific urls such as the one above.</p> <p>Also, if I switch to using HttpClient instead of HttpURLConnection, everything works fine:</p> <pre><code>// WORKS public void testCommonsHttpOAuthConsumerAndroidBug() throws Exception { for (int i = 0; i &lt; 2; ++i) { final HttpGet c = new HttpGet("https://api.tripit.com/oauth/request_token"); final CommonsHttpOAuthConsumer consumer = new CommonsHttpOAuthConsumer(api_key, api_secret, SignatureMethod.HMAC_SHA1); consumer.sign(c); final HttpResponse response = new DefaultHttpClient().execute(c); final InputStream is = response.getEntity().getContent(); while( is.read() &gt;= 0 ) ; assertTrue( response.getStatusLine().getStatusCode() == 200); } } </code></pre> <p>I've found <a href="http://groups.google.com/group/android-developers/browse_thread/thread/bc5454ffc71f77dc" rel="noreferrer">references</a> to what seems to be a similar problem elsewhere, but so far no solutions. If they're truly the same problem, then the problem probably isn't with signpost since the other references make no reference to it.</p> <p>Any ideas?</p>
