help with setting up custom bindings

[Farhad Taran]

I am trying to set up a module for roboguice in order to create custom bindings but I get the following error. looks like roboguice is not able to locate my module.

here is my module:

package com.ioc;

import android.content.Context;
import com.businessLogic.IPreferencesManager;
import com.businessLogic.ISessionManager;
import com.businessLogic.PreferencesManager;
import com.businessLogic.SessionManager;
import com.google.inject.AbstractModule;
import com.proxy.GenericProxy;
import com.proxy.IGenericProxy;

public class MainModule  extends AbstractModule {

    private Context context;


    public MainModule( Context context ) {
        this.context = context;
    }

    public void bind() {
        bind(IGenericProxy.class).toInstance( new GenericProxy());
        bind(IPreferencesManager.class).toInstance(new PreferencesManager(context));
        bind(ISessionManager.class).toInstance( new SessionManager(new PreferencesManager(context)));
    }

    @Override
    protected void configure() {

    }
}

my roboguice.xml file in the values folder:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string-array name="roboguice_modules">
        <item>com.ioc.MainModule</item>
    </string-array>
</resources>

here is the error message:
