Important hints for kangers. Due that aosp depreciated hex color values on this stage
I decided to remove also in colorpicker this support in general to be aosp consistent.
This means that for defaultValues only int colors are accepted. Two ways to do this.

1. Set defaultValue in xml code. Like android:defaultValue="0xff33be5e" or link it there
   to a integer color resource (before there was only the possibility to set eg "#33be5e" which
   is depreciated from aosp)

2. Do it with the new integrated method I did about 2 month ago. setNewPreviewColor(int color)
   Of course at this point you can do to get hex resources like it was before, eg
   setNewPreviewColor(getResources().getColor(com.android.internal.R.color.holo_blue_dark)

3. or do both :p

cheers
