    <p>My project has a light switch which has an IP address and port and accepts strings to control. I am trying to create an application to switch this on and off. My code works, however after the first click, there is a significant delay between the next click and the switch actually switching.</p> <p>I have a button for on and off. main.java:</p> <pre><code>package com.android.lswitch; import android.app.Activity; import android.os.Bundle; import android.view.View; import android.widget.Button; public class lightswitch extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); // Handle swon button Button swon = (Button) findViewById(R.id.swon); swon.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { sw(true); } }); // Handle swoff button Button swoff = (Button) findViewById(R.id.swoff); swoff.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { sw(false); } }); } private void sw(boolean swstate) { if (swstate == true) { Thread swonThread = new Thread(new swon()); swonThread.start(); } if (swstate == false) { Thread swoffThread = new Thread(new swoff()); swoffThread.start(); } } } </code></pre> <p>and button on java: package com.android.lswitch;</p> <pre><code>import java.io.BufferedWriter; import java.io.OutputStreamWriter; import java.io.PrintWriter; import java.net.InetAddress; import java.net.Socket; public class swon implements Runnable { public static final String SERVERIP = "10.0.0.25"; public static final int SERVERPORT = 4000; public void run(){ try { InetAddress serverAddr = InetAddress.getByName(SERVERIP); Socket socket = new Socket(serverAddr, SERVERPORT); String swon = "A55A6B0550000000FFFBDE0030C8"; String but0 = "A55A6B0500000000FFFBDE002066"; PrintWriter out = new PrintWriter( new BufferedWriter ( new OutputStreamWriter(socket.getOutputStream())),true); out.println(swon); out.println(but0); socket.close(); } catch(Exception e) { } finally { } } } </code></pre> <p>button off is virtually the same but with different strings. I'm new to android coding (and java coding) so can't see where the hold up is. Do I need to flush the strings somewhere? or is there a better way of tackling this project?</p> <p>Cheers</p>

    1. CODo you experience this delay also when using a different client than android? The problem could be on the server side

    2. COHi, no. I have a windows application where there is zero delay. Cheers

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.
