What is the best way to create drawables for different dpi

Question

Do you create the MDPI drawable first and just scale it accordinly to the .075/1.00/1.50/2 ratio by pixels in photoshop or do you recreate each individual drawable?

Answer 1

I use Inkscape, working with vector images as well, then export to the required raster size for the various resolutions. An article I wrote on producing icons from Inkscape can be found at https://tekeye.uk/android/android-launcher-icons-using-inkscape

Answer 2

Looks like there's a tool in Android Studio:

Expand your project folder in the Project View > right click on app > New > Image Asset

Icon Type: Action Bar and Tab Icons

Asset Type: Image

Choose the Path for original image (it should be big)

Shape: None (to make background transparent)

And it will generate the images in the appropriate drawable folders.
