title: Apply backgroundTint to background drawable for API 19
body: <p>The <code>backgroundTint</code> is correctly applied on API 23, but not on API 19. How can I get the drawable tinted for API 19 and below?</p>
  
  <pre><code>                    &lt;Button
                      android:layout_width="40dp"
                      android:layout_height="40dp"
                      android:id="@+id/AbResetBtn"
                      android:background="@android:drawable/stat_notify_sync"
                      android:backgroundTint="@color/button_material_light" /&gt;
  </code></pre>
  
  <p>Of course my <code>Activity</code> extends <code>AppCompatActivity</code>.</p>
