unknownhostexception

[Chuck Jagger]

I am attempting to retrieve a file from a URL connection. I've looked at all of the examples on the 'Net and have copied some in, but I simply can't figure out why I'm getting a "unknownhostexception" when running this code. I've tried multiple URL's - java.com, www.oracle.com, and the one in the example below, and they all return the unknownhostexception when doing the getInputStream function. Can someone please help me? I get this error right after the message indicated by #0 below appears.

 try {	
    	  URL                url; 
          URLConnection      urlConn; 
          DataInputStream    dis;

          url = new URL("http://montanacity.home.bresnan.net/clientraw.txt");
          // Note:  a more portable URL: 
          //* url = new URL(getCodeBase().toString() + "/ToDoList/ToDoList.txt");

          urlConn = url.openConnection(); 
          urlConn.setDoInput(true); 
          urlConn.setUseCaches(true);
          
          Toast.makeText(this, "#0", Toast.LENGTH_LONG).show();
          dis = new DataInputStream(urlConn.getInputStream()); 
          
          Toast.makeText(this, "#1", Toast.LENGTH_LONG).show();
          while ((clientraw = dis.readLine()) != null) {	
          	clientraw = dis.readLine();
          	Toast.makeText(this, "#2", Toast.LENGTH_LONG).show();
          	Toast.makeText(this, "#2"+clientraw, Toast.LENGTH_LONG).show();
          	recordct++;
          }
          dis.close(); 
    	} 
    
    catch (MalformedURLException mue) {
    	Toast.makeText(this, "#3 "+mue, Toast.LENGTH_LONG).show();
    } 
    catch (IOException ioe) {
    	Toast.makeText(this, "#4 "+ioe, Toast.LENGTH_LONG).show();
    }

Sorry..I should have included a couple more items of interest: 1) I'm developing this under the Android SDK. 2) I've tried running this application on both my development machine and on my android (both of which can access the URL) 3) I've verified that both my Droid as well as my development machine can reach all of the URL's that I've tried.

OK...after lots of searching and searching, I finally found the answer.

To do Internet communication in an Android app, this line must be in the AndroidManifest.xml:

<uses-permission android:name="android.permission.INTERNET" />

this goes just before the <application tagl
