title: Dotted line is actually not dotted when app is running on real Android device
body: <p>in my app I use XML defined vertical dotted line.</p>
  <pre><code>&lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot;?&gt;
  &lt;rotate xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;
      android:fromDegrees=&quot;90&quot;
      android:toDegrees=&quot;90&quot;&gt;
  &lt;shape
  
      android:shape=&quot;line&quot;&gt;
      &lt;stroke
  
          android:width=&quot;1dp&quot;
          android:color=&quot;@color/light_gray&quot;
          android:dashWidth=&quot;2dp&quot;
          android:dashGap=&quot;4dp&quot;
          /&gt;
  &lt;/shape&gt;
  </code></pre>
  
  <p>When I am nitpicking my layout in Android Studio, the line is rendered properly dotted, as it should, but problem comes out when I run the app on real device. The line is just solid with no gaps. What could be the problem? I tried many different devices including those running latest 4.3 Android. It look everywhere the same.</p>
