Small python script to pull out all versions of one or more drawables or resources, recreating their paths for all densities. Run with e.g.: python extract_assets.py ic_launcher

extract_assets.py

import sys, os

def findAsset(asset, folder):
    for file in os.listdir(folder):
        if os.path.isdir(folder + "/" + file):
            findAsset(asset, folder + "/" + file)
        if asset in file:
            inFile = "%s/%s" % (folder, file)
            outFolder = "exported/%s" % (folder)
            outFile = "%s/%s" % (outFolder, file)
            print(" - copying %s to %s" % (inFile, outFile))
            if not os.path.isdir(outFolder):
                os.makedirs(outFolder)
            with open(inFile, 'rb') as src, open(outFile, 'wb') as dst: dst.write(src.read())

def extractAsset(asset):
    findAsset(asset, 'src/main/res')

if len(sys.argv) == 1:
    print("Call with the name of the asset you want to extract, like:\npython %s ic_launcher ic_login" % sys.argv[0])

for i in range(1, len(sys.argv)):
    print("looking for resource %s" % sys.argv[i])
    extractAsset(sys.argv[i])
