How to use jersey client api in an android context?

Question

I´m trying to use my webservice via the jersey client api. This is my webservice:

@Path("/myresource")
@Component
@Scope("request")
public class MyResource {

@GET
@Produces(MediaType.TEXT_PLAIN)
@Path("test")
public String test(){
     return "test";
}

}

This is my Client:

public class MyClient {
public static void main(String[] args) {
 System.out.println(Client.create().resource( "http://testwebservice.de:8080/CompetenceNetwork/api/myresource/test" ).get( String.class ) );

}

}

Everythings works fine. Now I try this in an android class:

 TextView tv;
 public void onCreate(Bundle savedInstanceState)
 {
      super.onCreate(savedInstanceState);
      tv = new TextView(this);
      Client c = Client.create();
      WebResource r = c.resource("http://testwebservice.de:8080/CompetenceNetwork/api/myresource/test");
      String s = r.get(String.class);
      tv.setText(s);
      setContentView(tv);
   }

Nothing happends and after a few minutes I get the following exception:

What happens when you try to access the same URL in the Android web browser? — Mike Baranczak, Nov 04 '10 at 17:04
When I try this, nothing happens. The browser can´t open the site. LogCat says nothing at all. — Christine Bauers, Nov 05 '10 at 08:09

do you have the proper permissions set in your manifest.xml so that your app can use internet? I don't know the exact code but it should be easy enough to google it if you don't know it off the top of your head. Make sure to put it at the same level as application, NOT inside of it, and it seems to work better if you put it BEFORE the application tag as well.

It looks to me that you don't have your INTERNET permissions set in the android app. Without it, the android VM would prevent you from communicating outside the phone.
