I am using Design Support Library version 23.4.0. I have enabled the gradle flag:
defaultConfig { vectorDrawables.useSupportLibrary = tr
I had a similar problem long ago, it did not work by setting
vectorDrawables.useSupportLibrary = true
only worked when I created the "mipmap" folder, and the code used
imageView.setImageResource (R.mipmap.drawable_image)
It has more Info here
