cmd中之行adb

在用python编写脚本对android操作时，有时需要通过cmd命令直接对app操作。这样的好处是，如果你想对一页界面操作，不用一步一步的进行界面跳转，可以从主界面一下子调到你想要操作的界面。
通过os.popen()方法打开一个cmd命令

1、os.popen(“adb wait-for devices”)：等待连接设备

2、os.popen(“adb shell screencap -p /data/local/tmp.png”)：截屏后将图片以.png格式放在 /data/local/文件夹下

3、os.popen(“adb shell pull /data/local/“ +PATH(path+”/“ +timestamp + “.png”))：将手机/data/local/文件夹下文件传到手机文件夹下，并对图片以当时时间命名

4、os.popen(“adb shell am start -n com.xxx.xxx/com.xxx.xxx.plugins.PluginCenterActicity”)：直接跳转并打开com.xxx.xxx下的com.xxx.xxx.plugins.PluginCenterActicity界面

下边是手机截屏并上传到电脑中的代码：
