Android矢量Drawables VR PNG

Question

Having doubts about this. I know that vector drawables have the scaling advantage. But before i start making all my new icons in this way, is there any good reason to stick with the good old Pngs? I would really appreciate a good advice on this.

if providing only one version of your drawable instead than 3 or 4 scaled versions is not enough a good reason, then you can stick with drawables. Be aware that VectorDrawable are supported from lollipop onwards. For the platforms between ICS and Lollipop, the gradle plugin ( 1.5.0 ) creates a raster versions, of your vector drawable. You can specify the density you want to export adding

 generatedDensities = ['mdpi', 'hdpi', 'xhdpi', 'xxhdpi']

to the defaultConfig section of your build.gradle .

Edit

As point out by @Huteri, the support library v23.2 makes it easier to use it, adding support-vector-drawable and animated-vector-drawable . Have a look here
