MockRestAdapter crash with Observer

[danielgomezrico]

Related to this question http://stackoverflow.com/questions/31189159/mock-retrofit-service-with-mockito

Mocked service:

public class MockCustomerService implements CustomerService {

    @Override
    public Observable<Session> createSession(@Body Credential credential) {
        return Observable.just(createSession());
    }

    private static Session createSession() {
        return new Session("token");
    }
}

This is the real one:

public interface CustomerService {
  @POST("url")
  Observable<Session> createSession(@Body Credential credential);
}

Then I try to mockit in @Before method:

MockRestAdapter mockRestAdapter = MockRestAdapter.from(ApiManager.REST_ADAPTER);
        Customer.SERVICE = mockRestAdapter.create(CustomerService.class, new MockCustomerService());

But I get:

Is there something that I´m doing wrong? should I use MockRestAdapter manually? There´s no doc about how to use it and looks dangerous O_O

Thanks

Adding this lines to proguard it worked.

-keep class rx.** { *; }
-keepclassmembers class rx.xxxx { public *; }
