title: Implementing an option menu in Android Studio
body: <p>How do I implement an option menu in my android application? I tried code from <a href="http://developer.android.com/guide/topics/ui/menus.html" rel="noreferrer">Android Developer</a> but I get errors. Such as these: <strong>Element menu must be declared</strong>. Here is my code</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/new_game"
      android:icon="@drawable/ic_new_game"
      android:title="@string/new_game"
      android:showAsAction="ifRoom"/&gt;
  &lt;item android:id="@+id/help"
      android:icon="@drawable/ic_help"
      android:title="@string/help" /&gt;
  &lt;/menu&gt;
  &lt;manifest xmlns:android="http://schemas.android.com/apk/res/android"
  package="com.lucavanraalte.test" &gt;
  
  &lt;application
      android:allowBackup="true"
      android:icon="@mipmap/ic_launcher"
      android:label="@string/app_name"
      android:supportsRtl="true"
      android:theme="@style/AppTheme" &gt;
  
      &lt;activity android:name=".MainActivity" android:screenOrientation="portrait"&gt;
          &lt;intent-filter&gt;
              &lt;action android:name="android.intent.action.MAIN" /&gt;
  
              &lt;category android:name="android.intent.category.LAUNCHER" /&gt;
          &lt;/intent-filter&gt;
  
      &lt;/activity&gt;
  &lt;/application&gt;
  
  &lt;/manifest&gt;
  </code></pre>
