title: Why this strange border around ImageView
body: <p>I am getting strange border around my ImageView after updating android studio. The drawables are nine patch images. And they were not there on the previous gradle builds. Also I am testing this on an API 17 device.</p>

  <p>Here is the layout segment for the first arrow ImageView</p>
  
  <pre><code>&lt;ImageView
      android:id="@+id/splash_imgarrow"
      android:layout_height="20dp"
      android:layout_width="20dp"
      android:src="@drawable/slide_next"
      android:layout_toRightOf="@id/splash_img"
      android:layout_below="@id/splash_img"
      android:layout_marginTop="50dp"
      android:layout_marginLeft="0dp"
      android:layout_centerInParent="true"&gt;
  </code></pre>
