Android 的图片压缩其实压缩比很小。tinypng 大概可以压缩20%左右，我们工程的所有图片，之前是860k,压缩之后620k，少了200k。

使用：
1。安装python

2.使用pip进行安装tinypng的api：pip install –upgrade tinify

3。执行脚本,脚本如下：

import tinify
import os
import os.path
# reload(sys)
# sys.setdefaultencoding("utf-8")

tinify.key = "s8s--eMb8bFVe4Z-9fHEL9xUfehY6sKC" # AppKey
# src
fromFilePath = "D:/svn/bak2//src/main/res/drawable-xxhdpi" # src
toFilePath = "F:/pytest" # out


for root, dirs, files in os.walk(fromFilePath):
    for name in files:
        fileName, fileSuffix = os.path.splitext(name)
        if fileSuffix == '.png' or fileSuffix == '.jpg':
            toFullPath = toFilePath + root[len(fromFilePath):]
            toFullName = toFullPath + '/' + name
            fromFullPath = fromFilePath + root[len(fromFilePath):]
            fromFullName = fromFullPath + '/' + name

            if os.path.isdir(toFullPath):
                pass
            else:
                os.mkdir(toFullPath)

            source = tinify.from_file(fromFullName)
            source.to_file(toFullName)

其中：

tinify.key = “s8s–eMb8bFVe4Z-9fHEL9xUfehY6sKC” # AppKey 是你的APPkey,去tinypng申请
fromFilePath = “D:/svn/bak2/src/main/res/drawable-hdpi” # 是你要压缩的图片目录
toFilePath = “F:/pytest” # out 是压缩完之后的目录

备注：
申请tinypng api地址
