主要内容

• 热启动
• 冷启动
• 使用python脚本实现监控，分析

热启动

adb shell am start -W org.cnodejs.android.md/.ui.activity.LaunchActivity #打开应用
adb shell input keyevent 3   #Home

冷启动

adb shell am start -W org.cnodejs.android.md/.ui.activity.LaunchActivity
adb shell am force-stop org.cnodejs.android.md

基础功能实现

import subprocess
import time
import csv
def getstartapp_time():
    cmd = 'adb shell am start -W -n org.cnodejs.android.md/.ui.activity.LaunchActivity'
    p = subprocess.Popen(cmd,shell=True,stdout=subprocess.PIPE)
    thistime = 0
    for line in p.stdout.readlines():
        line = line.decode('utf8')
        if "ThisTime" in line:
            newline = line.split(':')
            thistime = newline[1]
            thistime = thistime.strip()
    return thistime
def force_stopapp():
    cmd = 'adb shell am force-stop org.cnodejs.android.md'
    subprocess.Popen(cmd,shell=True,stdout=subprocess.PIPE)
def run():
    with open('thistime.csv', 'w', newline='') as csvfile:
        spamwriter = csv.writer(csvfile, delimiter=' ',
                            quotechar='|', quoting=csv.QUOTE_MINIMAL)
        spamwriter.writerow(['title','time'])
    for x in range(20):
        thistime = getstartapp_time()
        with open('thistime.csv', 'a', newline='') as csvfile:
            spamwriter = csv.writer(csvfile, delimiter=' ',
                            quotechar='|', quoting=csv.QUOTE_MINIMAL)
            spamwriter.writerow(["thistime",thistime])
        time.sleep(3)
        force_stopapp()
        time.sleep(1)
run()
