Python获取android设备cpu和内存占用情况

46 次  2020-11-21  分类 : python教程

功能:获取android设备中某一个app的cpu和内存

环境:python和adb

使用方法:使用adb连接android设备,打开将要测试的app,执行cpu/内存代码

cpu获取代码如下:(输入参数为脚本执行时间)

# coding:utf-8

          print(cpu, now)
          cpu_list.append(cpu)
          break
        # 适配高版本手机

# csv头部
def write_head():
  headers = ['name:']
  headers.append(app_list[0])
  headers.append('init_cpu')
  with open('log_su/cpuinfo.csv', 'w+', newline='') as csvfile:
    writer = csv.DictWriter(csvfile, fieldnames=headers)

    header_row = next(reader)
    highs = []
    for row in reader:
      high = row[2]
      highs.append(high)
    # print(highs)

  wights = time_list
  highs_float = list(map(float, highs))
  # print(f"****{highs}")
  print(f"CPU值:{highs_float}")
  # 输出平均值

  #输出最低值和最高值
  highs_hl = sorted(highs_float)
  print(f"CPU最低值:{highs_hl[0]}")
  print(f"CPU最高值:{highs_hl[len(highs_hl)-1]}")

  # 根据数据绘制图形
  plt.figure(figsize=(11, 4), dpi=600)
  # 生成网格
  # plt.grid()
  plt.grid(axis="y")
  # 折线图
  if package_name[0] == 'com.oneapp.max.security.pro.cn':

  # 坐标轴范围

  plt.xlabel('time(H:Min:S)', fontsize=16)
  plt.ylabel("cpu_realtime(%)", fontsize=16)
  plt.title("cpu real time line chart", fontsize=24)
  plt.legend()

  # 横坐标显示间隔
  if len(wights) <= 15:
    pass
  else:
    t = int(len(wights) / 15)
    plt.xticks(range(0, len(wights), t))

  # 纵坐标显示间隔
  # plt.yticks(range(100, 300, 10))

  # 旋转日期
  plt.gcf().autofmt_xdate()

  # 展示每个坐标
  # for a, b in zip(wights, highs_float):
  #   plt.text(a, b, (a, b), ha='center', va='bottom', fontsize=8)

  # plt.show()

  time_now = time.strftime("%m%d-%H:%M:%S", time.localtime())
  path = "report/" + time_now
  plt.savefig(path)


# 自动识别当前需检测的
def name_app():
  cmd = 'adb shell dumpsys window | grep mCurrentFocus > log_su/name_info.csv'
  os.system(cmd)
  with open('log_su/name_info.csv', encoding='utf-8', mode='r') as f:
    lines = f.readlines()
    for line in lines:
      if 'mCurrentFocus' in line:
        name1 = line.split('/')[0].split(' ')
        name = name1[len(name1) - 1]

  with open('config/director.txt', encoding='utf-8', mode='w') as f_name:
    text = name
    f_name.write(text)
  print(f"将要监测的包名为:{text}")

#控制监测时间
def time_control():
  global filename
  while True:
    end_time = time.time()
    if (end_time - start_time)/60 >= tol_time:  #分钟
    # if end_time - start_time >= tol_time: # 秒
      break

    time.sleep(1)
    adb = "adb shell top -n 1 > log_su/adb_info.csv"
    d = os.system(adb)
    filename = "log_su/adb_info.csv"
    get_cpu()


if __name__ == "__main__":
  name_app()
  tol_time = int(input("请输入脚本执行时间(分钟):"))
  start_time = time.time()
  get_applist()
  write_head()
  time_control()
  write_report()
  mapping()

会在.py文件同级目录下生成3个文件夹,config、log_su、report,其中运行结果在report中

结果以是生成折线图,看起来直观,如下:

这里我解释下,cpu占比是adb获取的实时占比,但是满值并不一定是100%,比如这张图,用的是一个八核的手机,所以CPU满值是800%

内存获取代码如下:(输入参数为脚本执行时间)
