Fucking android...
Spent my whole day trying to tint (i.e. alter the image color) some svg with a PictureDrawable in an ImageView.
Went android underground, thought it had something to do with LAYER_TYPE_SOFTWARE (since this was required to render the underlying svg), tried my way through ColorFilters and ColorStateLists...
8 hours later I discovered that apparently YOU CANNOT TINT a PICTUREDRAWABLE - this only works with BitmapDrawable. *argh*
And not a word of mention in the fucking documentation *tit*
