    <p>I have a server that accepts a JSONObject and an Android app that sends a JSONObject to the server. The problem is that the server doesn't like the format of the JSONObject it receives. Can anyone tell me what I'm doing wrong?</p> <p>Android Client:</p> <pre><code>try{ Socket s = new Socket("67.194.98.244",13375); ObjectOutputStream oos = new ObjectOutputStream(s.getOutputStream()); org.json.JSONObject json = new org.json.JSONObject(); json.put("order", id); oos.writeObject(json); oos.flush(); oos.close(); }catch(Exception e){ e.printStackTrace(); } </code></pre> <p>And the python server:</p> <pre><code>class MyTCPServerHandler(SocketServer.BaseRequestHandler): def handle(self): try: data = json.loads(self.request.recv(1024).strip()) # process the data, i.e. print it: for key, value in data.iteritems(): with print_lock: print key, value if key == 'order': SubmitOrder(value,self) elif key == 'status': getStatus(value,self) else: with print_lock: print "no order" except Exception, e: print "Exception while receiving message: ", e </code></pre> <p>And here's the stack trace on Android:</p> <pre><code>09-21 21:53:49.804: W/System.err(27827): java.io.StreamCorruptedException 09-21 21:53:49.804: W/System.err(27827): at java.io.ObjectOutputStream.writeObject(ObjectOutputStream.java:1528) 09-21 21:53:49.804: W/System.err(27827): at java.io.ObjectOutputStream.writeObject(ObjectOutputStream.java:1481) 09-21 21:53:49.804: W/System.err(27827): at com.austinn.hamster.Print.sendCommand(Print.java:173) 09-21 21:53:49.804: W/System.err(27827): at com.austinn.hamster.Print$1$1.run(Print.java:92) 09-21 21:53:52.144: W/System.err(27827): java.io.StreamCorruptedException 09-21 21:53:52.144: W/System.err(27827): at java.io.ObjectOutputStream.writeObject(ObjectOutputStream.java:1528) 09-21 21:53:52.154: W/System.err(27827): at java.io.ObjectOutputStream.writeObject(ObjectOutputStream.java:1481) 09-21 21:53:52.154: W/System.err(27827): at com.austinn.hamster.Print.sendCommand(Print.java:173) 09-21 21:53:52.154: W/System.err(27827): at com.austinn.hamster.Print$1$1.run(Print.java:92) </code></pre>

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.
