Vector Drawables compatibility

Support Library supports Vector Drawables, but, if API level < 21, the following attributes are not covered:

• Background

• Compound drawables

• Selectors

• Layer lists

• Preference icons

• …​

In such cases, you have to insert in your Android Studio project an Image Asset.

Custom color

If you would like a custom color, it’s a pain!

1. Grab an SVG file with 24x24 size (for example from Material design icons).

2. Change the color in the SVG file.

3. Convert the SVG file in a PNG image asset, for example using Inkscape:

   $ inkscape -o drawable-mdpi/ic_name.png -w 24 -h 24 ic_name.svg
   $ inkscape -o drawable-hdpi/ic_name.png -w 36 -h 36 ic_name.svg
   $ inkscape -o drawable-xhdpi/ic_name.png -w 48 -h 48 ic_name.svg
   $ inkscape -o drawable-xxhdpi/ic_name.png -w 72 -h 72 ic_name.svg

4. I am confused regarding the need of a particular DPI of the images, however, if you want to set your images to 72 DPI, you can use, for example, ImageMagick:

   $ convert -units PixelsPerInch input.png -density 72 output.png
