    <p>I'm trying to make a connection between my <code>galaxy tab</code> and my <code>laptop</code>. So I'm trying to run server activity on my laptop and client activity on my tab, but it doesn't work. Here is the server and client code. Where is the mistake?</p> <p><strong>SERVER :</strong></p> <pre><code>public class MainActivity extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); TextView txt = (TextView)findViewById(R.id.textView1); int port = 12345; byte [] message = new byte [1500]; DatagramPacket p = new DatagramPacket (message,message.length); try { InetAddress serveraddr = InetAddress.getByName("192.168.1.116"); DatagramSocket s = new DatagramSocket (port,serveraddr); while (true){ s.receive(p); String text = new String (message,0,p.getLength()); txt.setText(text); } } catch (SocketException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } </code></pre> <p><strong>CLIENT :</strong></p> <pre><code>public class MainActivity extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); final EditText edt = (EditText)findViewById(R.id.editText1); Button btn = (Button)findViewById(R.id.button1); btn.setOnClickListener(new View.OnClickListener() { public void onClick(View arg0) { String msg = edt.getText().toString(); int port = 12345; try { DatagramSocket s = new DatagramSocket(); InetAddress local = InetAddress.getByName("192.168.1.116"); int msg_lenght = msg.length(); byte []message = msg.getBytes(); DatagramPacket p = new DatagramPacket(message,msg_lenght,local,port); s.send(p); } catch (SocketException e) { e.printStackTrace(); } catch (UnknownHostException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } } }); } </code></pre> <p>Here is the <strong>log</strong> : </p> <pre><code>09-17 23:49:55.190: D/dalvikvm(5892): Late-enabling CheckJNI 09-17 23:49:55.690: D/CLIPBOARD(5892): Hide Clipboard dialog at Starting input: finished by someone else... ! 09-17 23:49:59.590: D/AndroidRuntime(5892): Shutting down VM 09-17 23:49:59.590: W/dalvikvm(5892): threadid=1: thread exiting with uncaught exception (group=0x40c4f1f8) 09-17 23:49:59.590: E/AndroidRuntime(5892): FATAL EXCEPTION: main 09-17 23:49:59.590: E/AndroidRuntime(5892): android.os.NetworkOnMainThreadException 09-17 23:49:59.590: E/AndroidRuntime(5892): at android.os.StrictMode$AndroidBlockGuardPolicy.onNetwork(StrictMode.java:1099) 09-17 23:49:59.590: E/AndroidRuntime(5892): at libcore.io.BlockGuardOs.sendto(BlockGuardOs.java:175) 09-17 23:49:59.590: E/AndroidRuntime(5892): at libcore.io.IoBridge.sendto(IoBridge.java:463) 09-17 23:49:59.590: E/AndroidRuntime(5892): at java.net.PlainDatagramSocketImpl.send(PlainDatagramSocketImpl.java:182) 09-17 23:49:59.590: E/AndroidRuntime(5892): at java.net.DatagramSocket.send(DatagramSocket.java:307) 09-17 23:49:59.590: E/AndroidRuntime(5892): at com.example.udpclient.MainActivity$1.onClick(MainActivity.java:36) 09-17 23:49:59.590: E/AndroidRuntime(5892): at android.view.View.performClick(View.java:3620) 09-17 23:49:59.590: E/AndroidRuntime(5892): at android.view.View$PerformClick.run(View.java:14322) 09-17 23:49:59.590: E/AndroidRuntime(5892): at android.os.Handler.handleCallback(Handler.java:605) 09-17 23:49:59.590: E/AndroidRuntime(5892): at android.os.Handler.dispatchMessage(Handler.java:92) 09-17 23:49:59.590: E/AndroidRuntime(5892): at android.os.Looper.loop(Looper.java:137) 09-17 23:49:59.590: E/AndroidRuntime(5892): at android.app.ActivityThread.main(ActivityThread.java:4507) 09-17 23:49:59.590: E/AndroidRuntime(5892): at java.lang.reflect.Method.invokeNative(Native Method) 09-17 23:49:59.590: E/AndroidRuntime(5892): at java.lang.reflect.Method.invoke(Method.java:511) 09-17 23:49:59.590: E/AndroidRuntime(5892): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:978) 09-17 23:49:59.590: E/AndroidRuntime(5892): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:745) 09-17 23:49:59.590: E/AndroidRuntime(5892): at dalvik.system.NativeStart.main(Native Method) 09-17 23:50:34.320: I/Process(5892): Sending signal.

Guidance
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).
