getEntity call results in crash (using odata4j on a WCF service)

I am trying out odata4j in my android app to retrieve data from a DB that can be accessed from a WCF service. 

 ODataConsumer co = ODataConsumer.create("http://xxx.xx.xx.xxx:xxxx/Users");
 for(OEntity user : co.getEntities("Users").execute())
 {
      // do stuff
 }

However this crashes at the call to getEntities. I have tried a variety of other calls as well, such as 

 Enumerable<OEntity> eo = co.getEntities("Users").execute();            
 OEntity users = eo.elementAt(0);

However this also crashes at eo.elementAt(0).

The logcat doesn't tell me anything, and the callstack seems to be Suspended at ActivityThread.performLaunchActivity.

Entering "http://localhost:xxxx/Users" in my web browser on the other hand works as expected and returns the users in my DB in xml format.

Any ideas on how I can debug this?

Can you try this way.

OEntity oEntity;     
         OQueryRequest<OEntity>  oQueryRequest=  oDataJerseyConsumer.getEntities(entityName);
         List<OEntity>  list=  oQueryRequest.execute().toList();

         for (OEntity o : list) {
                List<OProperty<?>> props = o.getProperties();
                for (OProperty<?> prop : props) {
                    System.out.println(prop.getValue().toString());

                }

        }

To log all http requests/responses:

ODataConsumer.dump.all(true);

The uri passed to the consumer .create call should be the service root. e.g. .create("http://xxx.xx.xx.xxx:xxxx/"); Otherwise your code looks fine.

Note the Enumerable behaves like the .net type - enumeration is deferred until access. If you plan on indexing multiple times into the results, I'd suggest you call .toList() first.

Let me know what you find out.

Hope that helps,

I guess the call should be:

ODataConsumer co = ODataConsumer.create("http://xxx.xx.xx.xxx:xxxx");
for(OEntity user : co.getEntities("Users").execute())
{
     // do stuff
}

create defines service you want to connect but Users is the resource you want to query.
