Learn how to use the ADB command in Python

Using the ADB command in Python, you can import an OS module.

1 simple adb order.

such as: Os.system (' adb version ')

2 A somewhat complicated adb order.

such as: Os.system (' adb shell ' dumpsys activity | grep "Mfocusedactivity" "")

3 want to save the contents of the ADB read out.

such as: out = Os.popen (the ' adb shell ' dumpsys activity | grep "mfocusedactivity" "'). Read ()

To sum up: Os.system does not support reading, Os.popen supports reading.

Here's a transfer script to learn:

Import OS
import re


os.system (' adb version ')
os.system (' adb devices ') #os. System is out of read operation not supported
Os.popen (' adb shell ' dumpsys activity | grep "mfocusedactivity" "'). Read () #os. Popen supports read operations
print (out)

#下面的代码是获取当前窗口的component参数
def Getfocusedpackageandactivity (): Pattern

        = Re.compile (r "[A-za-z0-9\.] +/[a-za-z0-9\.] + ") #这里使用了正则表达式, the content of the output is restricted, only the string out like" Com.mediatek.factorymode/com.mediatek.factorymode.factorymode "is displayed
        Os.popen ("ADB shell dumpsys window Windows | Findstr \/| Findstr name= "). Read () #window下使用findstr
        list = Pattern.findall (out)
        component = List[0] #输出列表中的第一条字符串

        Return component
Print (Getfocusedpackageandactivity ())
