ImageView tint below L cannot reference Theme Attribute

I recently added different themes to my app and therefore need to have icons tinted differently for each theme.

<ImageView
        ...
        android:src="@drawable/ic_info"
        android:tint="?colorControlNormal"

But on API levels below 21 this does not work. I'm using vectordrawables and already tried to use 

vectorDrawables.useSupportLibrary = true

and

AppCompatDelegate.setCompatVectorFromResourcesEnabled(true);

but that didn't help either.

The tinting support documentation is quite ambiguous and with the combination of using VectorDrawables and referencing a theme color, I couldn't find any information.

currently trying to use:

<android.support.v7.widget.AppCompatImageView
    ...
    android:tint="?colorControlNormal"
    android:src="@drawable/icon"/>

which results in:

Finally found the issue!

By referencing the theme color ?colorControlNormal

you implicitly use a ColorStateList (abc_secondary_text_material_light.xml) which is not supported below L. Unless you are using <android.support.v7.widget.AppCompatImageView> and also use the tint attribute from the support lib app:tint attribute. So the proper tint attribute solved it in the end.

Try using:

<android.support.v7.widget.AppCompatImageView
    android:id="@+id/my_appcompat_imageview"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/my_image" // change to ur own.
    android:tint="#636363" // also change this part to our own case
/>

This work to API < 19
