dustin-graham / import_image_assets.py

Created November 13, 2015 23:52

imports image assets from a source directory into the res directory of an Android project. My designer gave me a directory of dpi-sized assets and this is an automated way to get them into the project quickly. The format this script expects is <nameoffile>_<densitymodifier>.<extension>. The files will be copied into the user-specified res folder…

	import os, sys, shutil

	legalResolutionModifiers = ["ldpi","mdpi","hdpi","xhdpi","xxhdpi","xxxhdpi"]

	# check inputs
	if len(sys.argv) != 3:
	print "illegal usage"
	sys.exit()

	sourceFolder = sys.argv[1]
