    <p>I have read this <a href="https://stackoverflow.com/questions/4837463/transfer-data-between-android-devices">Bluetooth Chat</a> post, and this <a href="https://stackoverflow.com/questions/7650690/transfer-a-file-between-android-devices">Transfer file</a> post.And I have two real android devices ,not AVDs, my intent is to set IP address and port in one device which acts as a Client while the other acts as a Server.</p> <p>They are using WIFI,and I have connected both of them to PC respectively.Get into adb shell ,and ping each other.It works. I have written client code like this:</p> <pre><code> Socket socket = new Socket("192.168.1.142",8888); InputStream in = socket.getInputStream(); byte[] buffer = new byte[in.available()]; Toast.makeText(this, String.valueOf(in.available()), Toast.LENGTH_LONG).show(); in.read(buffer); String msg = new String(buffer); Toast.makeText(this, msg, Toast.LENGTH_LONG).show(); </code></pre> <p>and the Server:</p> <pre><code>ServerSocket server = new ServerSocket(8888); while(true) { Socket client = server.accept(); OutputStream out = client.getOutputStream(); String msg = "Hello Android!"; out.write(msg.getBytes()); client.close(); } </code></pre> <p>I have add this </p> <p><code>&lt;uses-permission android:name="android.permission.INTERNET" /&gt;</code> to manifest.</p> <p>But no response. I have two questions:</p> <p>1.Why there is no response in my client?</p> <p>2.How to handle with sqlite3 database ,there must be something different with ordinary text files,but what is the difference?</p> <p>Any suggestions will be very appreciated.</p>

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.
