    <p>I am trying to connect a web server I have running in my android App however for some reason it's failing.</p> <p>I can connect to the webpage normally and using my phone's browser, I can also use the below code to connect to google but for some reason my code will not connect to my web server. If I host the server on port 80 I get error code 503 every time, if I host it on 8080 (which is preferable) I get a timeout exception which is below.</p> <pre><code>03-05 20:12:22.432: WARN/System.err(29254): java.net.SocketException: The operation timed out 03-05 20:12:22.602: WARN/System.err(29254): at org.apache.harmony.luni.platform.OSNetworkSystem.connectSocketImpl(Native Method) 03-05 20:12:22.602: WARN/System.err(29254): at org.apache.harmony.luni.platform.OSNetworkSystem.connect(OSNetworkSystem.java:125) 03-05 20:12:22.602: WARN/System.err(29254): at org.apache.harmony.luni.net.PlainSocketImpl.connect(PlainSocketImpl.java:227) 03-05 20:12:22.612: WARN/System.err(29254): at org.apache.harmony.luni.net.PlainSocketImpl.connect(PlainSocketImpl.java:521) 03-05 20:12:22.612: WARN/System.err(29254): at java.net.Socket.connect(Socket.java:1019) 03-05 20:12:22.612: WARN/System.err(29254): at org.apache.harmony.luni.internal.net.www.protocol.http.HttpConnection.&lt;init&gt;(HttpConnection.java:67) 03-05 20:12:22.612: WARN/System.err(29254): at org.apache.harmony.luni.internal.net.www.protocol.http.HttpConnectionManager$ConnectionPool.getHttpConnection(HttpConnectionManager.java:151) 03-05 20:12:22.612: WARN/System.err(29254): at org.apache.harmony.luni.internal.net.www.protocol.http.HttpConnectionManager.getConnection(HttpConnectionManager.java:73) 03-05 20:12:22.612: WARN/System.err(29254): at org.apache.harmony.luni.internal.net.www.protocol.http.HttpURLConnection.getHTTPConnection(HttpURLConnection.java:826) 03-05 20:12:22.612: WARN/System.err(29254): at org.apache.harmony.luni.internal.net.www.protocol.http.HttpURLConnection.connect(HttpURLConnection.java:812) 03-05 20:12:22.612: WARN/System.err(29254): at org.apache.harmony.luni.internal.net.www.protocol.http.HttpURLConnection.getResponseCode(HttpURLConnection.java:1275) 03-05 20:12:22.612: WARN/System.err(29254): at com.project.library.remailer.ServerSelect.downloadDirectory(ServerSelect.java:84) 03-05 20:12:22.622: WARN/System.err(29254): at com.project.main.NewMessage$3$1$1.run(NewMessage.java:156) </code></pre> <p>The code is:</p> <pre><code>try { URL url = new URL(directoryLocation); HttpURLConnection httpURLConnection = (HttpURLConnection) url .openConnection(); // The line below is where the exception is called int response = httpURLConnection.getResponseCode(); if (response == HttpURLConnection.HTTP_OK) { // Response successful InputStream inputStream = httpURLConnection.getInputStream(); // Parse it line by line BufferedReader bufferedReader = new BufferedReader( new InputStreamReader(inputStream)); String temp; while ((temp = bufferedReader.readLine()) != null) { // Parsing of data here } } else { Log.e("SAMES", "INCORRECT RETURN CODE: " + response); } } catch (MalformedURLException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } </code></pre> <p>When I try the code in the link suggested by CommonsWare for port 8080 I get the same error as before, the timeout exception.

    1. COI can also provide the webserver code if needed. I also have added internet to the manifest so that is not the problem

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).
