Cannot get searchview in actionbar to work

I am pretty new to java and android development; and I have been working on an app in which I want an action bar with a SearchView. I have looked at the google examples but I can not get it to work. I must be doing something wrong and I'm about to give up on app-development :D I have searched but I have not found anything helpful. Maybe you guys can help me :)

The problem: I get the search view to open as it should, but after that nothing happens at all, I've noticed that my searchManager.getSearchableInfo(getComponentName()) returns null. Also my hint that I've given is not displayed in my search box which leads me to believing that maybe the app can't find my searchable.xml? Enough talk :)

MainActivity.java

public class MainActivity extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.activity_main, menu);

        // Get the SearchView and set the searchable configuration
        SearchManager searchManager =
            (SearchManager) getSystemService(Context.SEARCH_SERVICE);
        SearchView searchView =
            (SearchView) menu.findItem(R.id.menu_search).getActionView();
        searchView.setSearchableInfo(
            searchManager.getSearchableInfo(getComponentName()));

        return true;
    }
}

searchable.xml

<?xml version="1.0" encoding="utf-8"?>
<searchable xmlns:android="http://schemas.android.com/apk/res/android"
    android:hint="@string/search_hint"
    android:label="@string/app_label">
</searchable>

SearchableActivity.java

package com.example.searchapp;

import android.app.ListActivity;
import android.app.SearchManager;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;

public class SearchableActivity extends ListActivity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.search);

        // Get the intent, verify the action and get the query
        Intent intent = getIntent();
        if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
          String query = intent.getStringExtra(SearchManager.QUERY);
          doMySearch(query);
        }
    }

    private void doMySearch(String query) {
        Log.d("Event",query);
    }
}

And here is a link to the referred project, I would be eternally grateful if someone was to help me with this!
