I just can't get Restlet on Android to work. I have the same jars, same generated classes etc. that I use in plain Java (it works there). Problem seems to be with the HttpClientHelper.

I also read this: http://wiki.restlet.org/docs_2.1/13-restlet/275-restlet/266-restlet.html.

Here's my code: 

import netflix.catalog.v2.Genre;
import org.restlet.engine.Engine;
import org.restlet.ext.net.HttpClientHelper;
import org.restlet.ext.odata.Query;

        Engine.getInstance().getRegisteredClients().clear();
        Engine.getInstance().getRegisteredClients().add(new HttpClientHelper(null)); 

        SystemDataObjectsService service = new SystemDataObjectsService();  

        Query<Genre> query = service.createGenreQuery("/Genres");


        for (Genre g : query) {
            Log.d(TAG, g.getName());
        }

Here's the trace:

I also tried to import org.restlet.ext.httpclient.HttpClientHelper (and any other HttpClientHelper that Eclipse suggests) which lead to a slightly different trace:

I don't know what else to do, if someone has a running Restlet/ oData android project, perhaps he/ she can give me a hint?

I have same issues. Found this link: stackoverflow.com/questions/6068303/android-restlet-https. Solution provided there didn't resolved my problems but maybe will help you... – cybevnm Nov 20 '12 at 18:08
Thanks, I tried that already. – Ascorbin Nov 24 '12 at 15:45
Can you post a reproducible code? – auselen Nov 26 '12 at 7:49
This looks like a DNS/IP connectivity issue. To be sure you could try to manually invoke Netflix OData service using the low level java.net.HttpURLConnection class – Jerome Louvel Nov 27 '12 at 7:25
