Guice Extensions MultiBindings not working with RoboActivity

Question

I cannot make Guice Multibindings work with RoboGuice.

When my activity extends android Activity, multibindings work just fine. When my activity extends RoboActivity, multibindings do not work, and the following exception is thrown:

3450-3450/com.example.guicetest E/AndroidRuntime﹕ FATAL EXCEPTION: main
com.google.inject.ProvisionException:
Unable to provision, see the following errors:
1) Multibinder is not initialized
at com.example.guicetest.MainActivity$1$1.configure(MainActivity.java:35)
(via modules: com.example.guicetest.MainActivity$1$1 ->
com.google.inject.multibindings.Multibinder$RealMultibinder)

at com.google.inject.internal.InjectorImpl.getInstance(InjectorImpl.java:1044)
at com.example.guicetest.MainActivity$1.onClick(MainActivity.java:41)

Android Studio project I've created declares following Gradle dependencies:

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile 'com.google.guava:guava:18.0'
    compile 'com.android.support:appcompat-v7:22.0.0'
    compile('com.google.inject.extensions:guice-multibindings:4.0-beta5') {
        exclude group: 'com.google.inject', module: 'guice'
    }
    compile('org.roboguice:roboguice:3.0.1') {
        exclude group: 'com.google.inject', module: 'guice'
    }
    provided('org.roboguice:roboblender:3.0.1') {
        exclude group: 'com.google.inject', module: 'guice'
    }
}

The module is as follows (part of MainActivity):

Button button = (Button) findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
     Injector injector = Guice.createInjector(new AbstractModule() {
                @Override
                protected void configure() {
                    bind(MyFooService.class).in(Singleton.class);
                    Multibinder<MyInterface> processors = Multibinder.newSetBinder(binder(), MyInterface.class);
                    processors.addBinding().to(MyBarImpl.class);
                    processors.addBinding().to(MyQuxImpl.class);
                }
            });

            MyFooService fooService =injector.getInstance(MyFooService.class);
            Log.d("TEST", String.valueOf(fooService.implementations.size()));
        }
    });

If I invoke 'gradle -q :app:dependencies' I receive:

compile - Classpath for compiling the main sources.
+--- com.android.support:appcompat-v7:22.0.0
|    \--- com.android.support:support-v4:22.0.0
|         \--- com.android.support:support-annotations:22.0.0
+--- com.google.inject:guice:3.0
|    \--- javax.inject:javax.inject:1
+--- com.google.inject.extensions:guice-multibindings:3.0
\--- org.roboguice:roboguice:3.0.1

but still I've got dalvik error:

com.android.dex.DexException: Multiple dex files define Lcom/google/inject/Module;

When I test 'guice-3.0-no_aop' library, 'com.google.inject.Module' class is both in 'guice-3.0-no_aop' and 'roboguice-3.0.1'.

I'm pretty stuck here :)

@diego I'm sure you have a module as an anonymous class in `com.example.guicetest.MainActivity`; I can tell from your exception stacktrace. — durron597, Apr 27 '15 at 20:57
@diego If you want to include more code, please [edit] it into your original question. — durron597, Apr 27 '15 at 20:57
@Tavian Barnes if I switch to guice-multibindings:3.0 then I receive java.lang.NoClassDefFoundError: com/google/inject/internal/util/$ImmutableList from the Android Studio compiler. — diego, Apr 27 '15 at 21:01
Anybody? Am I the only entity unsuccessfully trying to make RoboGuice and Multibindings work together? — diego, Apr 28 '15 at 19:34

I've made it. It turns out, at least for me, that Multibindings work only with Roboguice 2. My Gradle configuration that finally worked:

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile ('com.android.support:appcompat-v7:22.0.0'){
        exclude group: 'com.google.inject', module: 'guice'
    }
    compile(group: 'com.google.inject', name: 'guice', version: '3.0', classifier: 'no_aop')
    compile('com.google.inject.extensions:guice-multibindings:3.0') {
       exclude group: 'com.google.inject', module: 'guice'
    }
    compile('org.roboguice:roboguice:2.0') {
        exclude group: 'com.google.inject', module: 'guice'
    }
}

I'd be truly grateful if someone could comment on using Multibindings with higher Roboguice versions...
