title: (Android)Menu Icon image is not display properly in different devices
body: <p>I have created menu as below :</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/edit_or_save_button"
      android:icon="@drawable/edit_button"
      android:orderInCategory="100"
      android:showAsAction="always"
      android:title="@string/edit_or_save_button"/&gt; 
  
  &lt;/menu&gt;
  </code></pre>
  
  <p>But here edit_button icon looks small in one device and bigger in another device as attached in screen shot. I have tried by putting images in <strong>different drawable(xhdpi,hdpi,ldpi)</strong> but it is not changing.</p>
