Body
My application has a UI (implemented with an Activity) and a service (implemented with the IntentService). The service is used to send data (synchronous, using NetworkStream.Write) to a remote server as well as to update the transmission status to the UI (implemented using Broadcast Receiver method). Here is my problem: <ul> <li>The application works properly if the size of the buffer used for the NetworkStream.Write is 11 KB or less.</li> <li>However, if the size of the buffer is larger than 11 KB, say 20 KB (this size needed in order to send jpg images), then the sevice keeps working properly (verified with log file), nonetheless the UI its gone (similar as if device's back button is pushed) and I can't find the way to bring it back. Its important to point out that in this case the Activity its not going into OnStop() nor OnDestroy() states.</li> <li>At first I thought this would be some ApplicationNotResponding related issue due to a server delay, yet the UI crashes after about 5 sec.</li> <li>Moreover, this only happens with the Hardware version. The emulator version works fine. <pre><code>// SEND STREAM: Byte[] outStream = new Byte[20000]; // -- Set up TCP connection: -- TcpClient ClientSock = new TcpClient(); ClientSock.Connect("myserver.com", 5555); NetworkStream serverStream = ClientSock.GetStream(); serverStream.Write(outStream, 0, outStream.Length); serverStream.Flush(); // . . . // RECEIVE STREAM: inStream.Initialize(); // Clears any previous value. int nBytesRead = 0; nBytesRead = serverStream.Read(inStream, 0, 1024); // -- Closing communications socket: -- ClientSock.Close(); </code></pre></li> </ul>

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.
