menu does not inflate
<p>I am trying to inflate android menu but I fail to inflate it:</p>

<p>here is my menu.xml:</p>

<pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;menu xmlns:android="http://schemas.android.com/apk/res/android"&gt;
    &lt;item
        android:id="@+id/itemPrefs"
        android:background="#f000"
        android:title="@string/titlePrefs"
        android:icon="@drawable/ic_menu_black_24dp"&gt;
    &lt;/item&gt;
&lt;/menu&gt;
</code></pre>

<p>and here is where I inflate my main activity:</p>

<pre><code>@Override public boolean onCreateOptionsMenu(Menu menu) {
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.menu, menu);
        return true;
    }
</code></pre>

<p>I am using LG G3 and menu is not showing :-(</p>

<p>thanks for your help</p>
