I am having a problem with calling a ext function in odata4j in android client consumer.
E.g. the function “Movies” of Netflix public service.
METADATA of function:
<FunctionImport Name="Movies" EntitySet="Titles" ReturnType="Collection(Netflix.Catalog.v2.Title)" m:HttpMethod="GET"/>
and my code:
ODataConsumer c = ODataConsumer.create("http://odata.netflix.com/Catalog/");
c.dump.all(true);
Enumerable<OObject> e = c.callFunction("Movies").execute();
With this callFunction method ends with following error.

Interesting is, when I delete row with c.dump.all(true) the callFunction is without error but cannot access data.

I am not sure if I understand correctly the callFunction method. There are EntitySet and ReturnType attributes in metadata entry of the function but I suppose I can access the result as OObject(s). Or am I wrong? Is there any example how to get function response and access its data.
Could anybody help me with this please. Thank you very much.

I’ve met the same problem. As the exception error message suggested, Odata4j 0.5 currently does not handle the response from a function call. If you have a look at the source code, you will see.
