title: Dummy ImageView not showing image
body: <p>It is showing the image in the Android Studio preview but doesn't show anything when I'm running this on my device. Any ideas why this happens? What's wrong with my code?</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
      android:layout_width="match_parent"
      android:layout_height="match_parent"&gt;
      &lt;ImageView
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:src="@drawable/myimage" /&gt;
  
  &lt;/RelativeLayout&gt;
  </code></pre>
