system.img镜像转换为system.new.dat + system.transfer.list
android 8.1上面验证，支持所有的android版本，直接放到sdk中执行即可。
img2sdat.py
#!/usr/bin/env python
#coding=utf-8
import sys
if sys.hexversion < 0x02070000:
print >> sys.stderr, "Python 2.7 or newer is required."
sys.exit(1)
from hashlib import sha1 as sha1
import common
import sparse_img
OPTIONS = common.OPTIONS
try:
PARTITION_NAME = str(sys.argv[1])
SYSTEM_IMG = str(sys.argv[2])
OUTPUT_DIR = str(sys.argv[3])
OPTIONS.outpath = OUTPUT_DIR
except IndexError:
print('\nUsage: img2sdat.py \n')
print(' eg: img2sdat.py system system.img system_new\n')
print(' : input partition name')
print(' : input image name')
print(' : image new dat dir')
print(' Visit xda thread for more information.\n')
try:
input = raw_input
except NameError: pass
input('Press ENTER to exit...')
sys.exit()
def main(argv):
system_tgt = sparse_img.SparseImage(SYSTEM_IMG);
system_tgt.ResetFileMap()
system_diff = common.BlockDifference(PARTITION_NAME, system_tgt, src=None, check_first_block=False, version=4)
if __name__ == '__main__':
main(sys.argv[1:])
目前transfer.list已经最新的支持version=4， system.transfer.list版本进化，这里针对不同的android版本，传入不同的version=1/2/3/4即可
对common.py打patch
diff --git a/tools/releasetools/common.py b/tools/releasetools/common.py

tmpdir = tempfile.mkdtemp()
OPTIONS.tempfiles.append(tmpdir)

然后即可在android的根目录下面执行如下命令：

即可在目录
out/target/product/xxxx/sdat看到有system.new.dat与system.transfer.list文件生成。
命令格式： img2sdat.py 分区名 img路径 new.dat路径
