I can receive data on c# UDP server i have written through this code but instead of string i have typed in the editText box ... i receive android.widget.EditText#xxxxxx on the server. Some Help would be much appreciated.

You need to ask for the contents of the EditText, not the String representation of the variable... Change this line:
String cmd= editText1.toString();
To:
String cmd = editText1.getText().toString();

My problem is my client side code stuck when it goes to socket.receive() method. I started my mobile data at both sides. Started Hotspot at server side and connected to it from client.
My problem is my client side code stuck when it goes to socket.receive() method
It blocks.
InetAddress group = InetAddress.getByName("224.0.0.3");
The problem is here. Multicast addresses in the range 224.0.0.0 to 224.0.0.255 are reserved for low-level multicast support operations. Use an address in the range 224.0.1.0 to 239.255.255.255, but see also RFC 2365.
sock.setBroadcast(true);
Unnecessary. Remove. You aren't broadcasting, you are multicasting.
byte []b3=new byte[1024];
DatagramPacket packet;
b3=msg.getBytes();
You don't need to initialize b3 when you reassign it two lines later.
finally
{
sock.close();
}
You are closing the socket inside the while (true) loop. So it will send one multicast and then exit with a 'socket closed' exception, which you haven't reported here. Remove.
String s = new String(packet.getData());
That should be new String(packet.getData(), packet.getOffset(), packet.getLength().
try to set able this enable socket.setBroadcast(true);
byte[] buf = new byte[256];
packet = new DatagramPacket(buf, buf.length);
socket.setBroadcast(true);
socket.receive(packet);
I have 3 buttons to turn on a different led, using wifi. What am I trying to do is to start a thread when a button is pressed. The thread will do a networking stuff which is to send a String of instruction code. But when I pressed the button, it stops running. And I want to display the exception in the toast if there is an exception occured. Please help.
Here is the code:
This is the activity that will display 3 buttons.

public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.display_lights_menu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);

}

cs.sendInstruction("0402");
}
public void powerLamp3(View view){

}
}
And this is the activity that will execute the thread.

First, I would read up on Android activity lifecycle. Personally I think this is the way begin to address the issue -
http://developer.android.com/training/basics/activity-lifecycle/index.html
Another option to investigate -
android:configChanges="orientation|keyboardHidden|screenSize"
how to stop activity recreation on screen orientation?
Try this in your Activity Tag of Manifest file :
<activity android:name=".MyActivity"
android:configChanges="orientation|keyboardHidden"
android:label="#string/app_name">
Here Orientation refers to Configuration changes which you want to handle by your own.
To declare that your activity handles a configuration change, edit the appropriate <activity> element in your manifest file to include the android:configChanges attribute with a value that represents the configuration you want to handle.
Use onSaveInstanceState() and onRestoreInstanceState() if you want to restore your previous state of an activity.
Refer this also
You may try to call setRequestedOrientation() in you activity so the orientation is forced.

I have no errors and its not crashing buts its not listening to my incoming message coming in and it is not displaying it
Try using:
while(s.isConnected() && r.hasNext()) {
String input =r.nextLine();
}
Your while loop currently only checks to see if you are connected, and has the potential to be an infinite loop. Your Scanner, r, on the other hand will not have an infinite amount of data, so repeatedly calling nextLine() means you'll eventually run out of data to read, and get the NoSuchElementException that you have.
Edit: As codeMagic mentioned in the comments, you should call setText() on the UI thread in onPostExecute() and not in doInBackground() as that will just result in more exceptions once you fix this one.
I have a problem, I can not establish a connection with my bluetooth shield, I've been with another application and if the device works, indicated by a light that is connected, but with this app, that does not happen. the app crashes when this method is called mmSocket.connect (), if this is not bad socket acquiring

what is the UUID you are providing?
To get connected to any bluetooth profile running on a remote device, you need to establish socket connection with the UUID [of the service you want to connect.].
For details list on UUID of different services, refer to assigned numbers.pdf in www.bluetooth.org
