title: Tinting ImageView not working on Android 5.0. Ideas how to make it work again?
body: <p>In an application I've built I noticed that the ImageViews are not tinted on devices running the new Android Lollipop. This is the code that used to work correctly on older versions of the OS:</p>
  
  <pre><code>&lt;ImageView
              android:layout_width="40dp"
              android:layout_height="40dp"
              android:layout_gravity="bottom|right"
              android:contentDescription="@string/descr_background_image"
              android:src="@drawable/circle_shape_white_color"
              android:tint="@color/intent_circle_green_grey" /&gt;
  </code></pre>
  
  <p>and this is the drawable that is loaded in the ImageView:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="oval" &gt;
      &lt;gradient android:startColor="@color/white" android:endColor="@color/white"
          android:angle="270"/&gt;
  &lt;/shape&gt;
  </code></pre>
  
  <p>Once again, this is working correctly on devices running JellyBean/Kitkat, but the tint has no effect on devices running Lollipop. Any ideas how to fix it? Is it a bug in the OS, or should I start tinting the image differently?</p>
