My server class is:</p> <pre><code> public class MainActivity extends Activity { private Boolean shouldRestartSocketListen=true; TextView tv1; //MulticastLock lock; static String UDP_BROADCAST = "UDPBroadcast"; DatagramSocket socket; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); tv1=(TextView)findViewById(R.id.textView1); startListenForUDPBroadcast(); // lock.release(); } private void listenAndWaitAndThrowIntent(InetAddress broadcastIP, Integer port) throws Exception { byte[] recvBuf = new byte[15000]; if (socket == null || socket.isClosed()) { socket = new DatagramSocket(port, broadcastIP); //socket.setBroadcast(true); } //socket.setSoTimeout(1000); DatagramPacket packet = new DatagramPacket(recvBuf, recvBuf.length); Log.e("UDP", "Waiting for UDP broadcast"); socket.receive(packet); String senderIP = packet.getAddress().getHostAddress(); String message = new String(packet.getData()).trim(); // Log.e("UDP", "Got UDB broadcast from " + senderIP + ", message: " + message); tv1.setText(message); // broadcastIntent(senderIP, message); socket.close(); } private void broadcastIntent(String senderIP, String message) { Intent intent = new Intent(MainActivity.UDP_BROADCAST); intent.putExtra("sender", senderIP); intent.putExtra("message", message); sendBroadcast(intent); } Thread UDPBroadcastThread; void startListenForUDPBroadcast() { UDPBroadcastThread = new Thread(new Runnable() { public void run() { try { InetAddress broadcastIP = InetAddress.getByName("192.168.1.255"); //172.16.238.42 //192.168.1.255 Integer port = 11111; while (shouldRestartSocketListen) { listenAndWaitAndThrowIntent(broadcastIP, port); } //if (!shouldListenForUDPBroadcast) throw new ThreadDeath(); } catch (Exception e) { Log.i("UDP", "no longer listening for UDP broadcasts cause of error " + e.getMessage()); } } }); UDPBroadcastThread.start(); } void stopListen() { shouldRestartSocketListen = false; socket.close(); } public void onCreate() { }; @Override public void onDestroy() { stopListen(); } public IBinder onBind(Intent intent) { return null; } } </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.

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).
