java.lang.UnsupportedOperationException: Can't convert to color: type=0x2

Hi,

First off, great work with this library. Looks absolutely gorgeous.
I was using it and suddenly in the last few days I got the same error as the one here:
#4

It works if I make my own selector_toolbar_button but putting exact colors such as this:

my_selector_toolbar_button:

<?xml version="1.0" encoding="utf-8"?>
    <selector xmlns:android="http://schemas.android.com/apk/res/android">
        <item android:state_pressed="true">
            <shape android:shape="rectangle">
                <solid android:color="#009688" />
            </shape>
        </item>

        <item android:state_focused="true">
            <shape android:shape="rectangle">
                <solid android:color="#009688" />
            </shape>
        </item>

        <item>
            <shape android:shape="rectangle">
                <solid android:color="#009688" />
            </shape>
        </item>
    </selector>

However if I use this, then the outcome is not as expected. The rectangle button color does not take up the whole button height, and the button in the toolbar appears before the FAB button disappears.

Here's the xml file where I'm using this button:

<?xml version="1.0" encoding="utf-8"?>

        android:fadingEdgeLength="30dp"
        app:layout_anchor="@id/app_bar"
        app:layout_anchorGravity="right|end"
        android:onClick="openURL"/>

    <android.support.design.widget.FloatingActionButton

        app:layout_anchor="@id/app_bar"
        app:layout_anchorGravity="bottom|end"
        android:onClick="openURL"/>

</android.support.design.widget.CoordinatorLayout>

I've also tried removing the
android:drawableLeft="@drawable/ic_shopping_cart_24dp"

As the stackoverflow post you linked to the other issue said it might be an out of memory exception where the image used might have a higher resolution.

Any idea what might be the issue? And just to state again, this has happened recently when I have not made any changes to this part of the code.

Just realized that it occurs in API level < 19 as you can't use attributes to define colors. Works fine post 19.

Interesting. Let me look into this.
