1、将adb logcat内容输出到控制台

import subprocess

logcat = subprocess.Popen(["adb", "logcat"], stdout=subprocess.PIPE)
try:
    flag = 0
    while not logcat.poll():
        line = logcat.stdout.readline()
        if line:
            formatted_line  = str(line,encoding="utf-8")
            print(formatted_line)
        else:
            break
except  KeyboardInterrupt:
    exit(0)
