title: Android: unable to change color of back arrow navigation icon
body: <p>I'm using new android appcompat toolbar.  I need to set the same custom color to both burger icon and back arrow icons.  Using drawerArrowStyle allows me to change burger icon but not the arrow. The issue is only on Lollipop devices, anything pre-lollipop is fine.  </p>

  <p>Here is the code:</p>
  
  <p>Toolbar:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:local="http://schemas.android.com/apk/res-auto"
      android:id="@+id/toolbar"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:minHeight="?attr/actionBarSize"
      android:background="@color/my_primary"
      local:theme="@style/My.Toolbar"
      local:popupTheme="@style/ThemeOverlay.AppCompat.Light" /&gt;
  </code></pre>
  
  <p>Style.xml: </p>
  
  <pre><code>&lt;style name="Theme.Base" parent="Theme.AppCompat.Light"&gt;
      &lt;!-- All customizations that are NOT specific to a particular API-level can go here. --&gt;
      &lt;item name="windowActionBar"&gt;false&lt;/item&gt;
      &lt;item name="android:windowNoTitle"&gt;true&lt;/item&gt;
      &lt;!-- colorPrimary is used for the default action bar background --&gt;
      &lt;item name="colorPrimary"&gt;@color/my_primary&lt;/item&gt;
      &lt;!-- colorPrimaryDark is used for the status bar --&gt;
      &lt;item name="colorPrimaryDark"&gt;@color/black&lt;/item&gt;
    &lt;/style&gt;
  
      &lt;style name="My.Theme" parent="Theme.Base"&gt;
         &lt;item name="drawerArrowStyle"&gt;@style/DrawerArrowStyle&lt;/item&gt;
      &lt;/style&gt;
  
      &lt;style name="My.Toolbar" parent="Theme.AppCompat.NoActionBar"&gt;
        &lt;!-- color of the title text in the Toolbar, in the Theme.AppCompat theme:  --&gt;
        &lt;item name="android:textColorPrimary"&gt;@color/my_actionbartext&lt;/item&gt;
  
        &lt;!-- necessary to support older Android versions.--&gt;
        &lt;item name="actionMenuTextColor"&gt;@color/my_actionbartext&lt;/item&gt;
  
        &lt;item name="android:textColorSecondary"&gt;@color/my_actionbartext&lt;/item&gt;
      &lt;/style&gt;
  
      &lt;style name="DrawerArrowStyle" parent="Widget.AppCompat.DrawerArrowToggle"&gt;
              &lt;item name="color"&gt;@color/my_actionbartext&lt;/item&gt;
      &lt;/style&gt; 
  </code></pre>
  
  <p>I've tried using solution from <a href="https://stackoverflow.com/questions/27861102/actionbardrawertoggle-v7-arrow-color">here</a> but it didn't work.  Anyone has any ideas? </p>
