bah, you did say that... I am undercaffeinated right now, it's only 9am


Here's what I am trying:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
     android:orientation="vertical"
     android:layout_width="fill_parent"
     android:layout_height="fill_parent"
     >
<TextView
    android:id="@+id/myText"
     android:layout_width="fill_parent"
     android:layout_height="wrap_content"
     android:text="@string/hello"
     />
</LinearLayout>

package test.inettest;

import java.net.InetAddress;
import java.net.UnknownHostException;

import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;

public class Activity1 extends Activity {

    String myHostname = "testarossa";

     /** Called when the activity is first created. */
     @Override
     public void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.main);
         TextView t = (TextView)findViewById(R.id.myText);
         try {
          t.setText(InetAddress.getByName(myHostname).toString());
         } catch(UnknownHostException exc) {
          t.setText("UNKNOWN HOST EXCEPTION");
         }
     }
}

When I run the app in the emulator, it says UNKNOWN HOST EXCEPTION.

Now, consider that I'm trying to resolve the NetBIOS name of my laptop.
My guess is that Android can't automatically resolve the NetBIOS name of
the computer. Running on the desktop, Java SE will receive the call to
getByName, pass the hostname on to Windows and Windows will pass back
the LAN address. Windows has ability to resolve NetBIOS names. But in an
Android app, there is no built-in facility to resolve NetBIOS hostnames
(as far as I know :>)

If you set serverNameStr to some globally resolvable hostname like
www.google.com or www.lobosstudios.com, what happens?

(I'm still not sure why you're getting 81.200.64.50, but that's mostly
because I haven't seen your code, other than that one line that you
already gave us)
