获取应用的包名和activity

adb logcat | findstr START

I/ActivityManager(  785): START u0 {act=android.intent.action.MAIN cat=[android.
intent.category.LAUNCHER] flg=0x10200000 cmp=com.xxx.ordersystem/.activity.We
lcomeActivity bnds=[540,960][798,1248]} from uid 10015 on display 0 from pid 177
4

aapt dump badging xxx.apk

package: name='com.xxx.ordersystem' versionCode='123' versionName='1.6.0'
sdkVersion:'14'
launchable-activity: name='com.xxx.ordersystem.activity.WelcomeActivity'  lab
el='' icon=''

启动时间

冷启动

每次杀掉应用进程启动

adb shell am start -W -n package/activity
Starting: Intent { cmp=com.xxx.ordersystem/.activity.WelcomeActivity }
Status: ok
Activity: com.xxx.ordersystem/.activity.WelcomeActivity
ThisTime: 317
TotalTime: 317
WaitTime: 326
Complete

ThisTime的值为启动时间

热启动

每次从后台启动应用

编写Python脚本自动获取启动时间

可以有两种方式

import os
import time
import csv


class App:
    def __init__(self):
        self.package = 'com.xxx.xxx'
        self.activity = '/.xxx.xxxActivity'
        self.content = ''
        self.start_time = None

    def launch_app(self):
        "启动app"
        cmd = r'adb shell am start -W -n {package}{activity}'.format(package=self.package,
                                                                     activity=self.activity)
        self.content = os.popen(cmd).readlines()

    def stop_app(self):
        '停止app'
        # cmd = r'adb shell am force-stop {}'.format(self.package)  # 冷启动杀进程
        cmd = r'adb shell input keyevent 3'  #热启动返回
        os.popen(cmd)

    def get_launch_time(self):
        "得到启动时间"
        for i in self.content:
            if i.startswith('ThisTime'):
                self.start_time = i.split(':')[1].strip()
                break
        return self.start_time


class Controller:

    def __init__(self, count):
        self.app = App()
        self.count = count
        self.data = [('timestramp', 'start_time')]

    def test_process(self):
        "单次运行"
        self.app.launch_app()
        time.sleep(5)
        starttime, ctime = self.app.get_launch_time(), time.strftime('%Y-%m-%d %H:%M:%S', time.localtime())
        self.app.stop_app()
        time.sleep(3)
        self.data.append((ctime, starttime))

    def run(self):
        "执行入口"
        for i in range(self.count):
            self.test_process()
        self.save_date()

    def save_date(self):
        "保存数据"
        csvfile = open('start_time1.csv', 'w')
        writer = csv.writer(csvfile)
        writer.writerows(self.data)
        csvfile.close()


if __name__ == '__main__':
    p = Controller(10)
    p.run()

cpu

获取cpu数据命令

adb shell dumpsys cpuinfo | findstr "packagename TOTAL"
  30% 14862/com.xxx.xxx: 29% user + 0.7% kernel / faults: 4976 minor
4.5% TOTAL: 4.1% user + 0.4% kernel + 0% softirq

这里表示:当前cpu的总占用为4.5%， com.xxx.xxx的cpu占用为4.5% * 30%

流量

获取流量数据

adb shell ps | findstr com.xxx.ordersystem

USER     PID   PPID  VSIZE  RSS     WCHAN    PC        NAME
u0_a592   24393 360   2291360 174244 ffffffff 00000000 S com.xxx.ordersystem

24393为应用的PID

adb shell cat /proc/24393/net/dev

wlan0中的Receive和transmit之和为当前流量数据，运行app一段时间后再次获取流量数据，计算差值即可得到当前时间段内的流量消耗值

电量

获取电量数据

adb shell dumpsys battery
Current Battery Service state:
  (UPDATES STOPPED -- use 'reset' to restart)
  AC powered: false
  USB powered: true
  Wireless powered: false
  status: 1
  health: 2
  present: true
  level: 32
  scale: 100
  voltage: 3819
  temperature: 218
  technology: Li-poly

level值为电量信息

内存

获取内存数据

adb shell top | findstr package

adb shell top -d 1 | findstr com.xxx.xxx  # -d 刷新间隔时间 1s
PID PR CPU% S  #THR     VSS     RSS PCY UID      Name
14862  5   5% S    56 2404772K 176380K  tv u0_a149  com.xxx.xxx
14862  5   4% S    56 2404772K 166136K  tv u0_a149  com.xxx.xxx

VSS - Virtual Set Size 虚拟耗用内存,单个进程全部可访问的地址空间
RSS - Resident Set Size 实际使用物理内存,单个进程实际占用的内存大小
关注这两个值变化即可

FPS和过度渲染
