Python小工具-查看内存和CPU

 通过循环执行adb的查看内存命令来进行内存比较，分析内存是否泄漏：

def get_total_pss():

    if os.path.exists('total.txt'):
        with open('total.txt','r+') as f2:
            res = f2.readlines()
            print(res)
            f2.seek(0)
            f2.truncate()
    with open('total.txt', 'at') as f1:
        f1.write('TOTAL：
')
    package = "com.wangpos.by.cashier3"
    cmd = "adb shell dumpsys meminfo {}".format(package)
    total = "TOTAL"
    while True:
        lines = os.popen(cmd).readlines()
        for line in lines:
            if total in line:
                # print(type(line))
                total_result = [i for i in re.split(' ',line) if i !='']
                print(total_result)
                with open('total.txt','at') as f:
                    f.write(total_result[1]+'
')
                    sleep(5)

CPU: 

def get_cpu():
    package = "com.wangpos.by.cashier3"
    cmd = "adb shell top -m 10 -n 1 -s cpu"

    while True:
        lines = os.popen(cmd).readlines()
        print(lines)
        for line in lines:
            if package in line:
                result = [i for i in re.split(' ',line) if i !='']
                with open('cpu.txt', 'at') as f:
                    f.write(result[2])
                    print(float(result[2].strip('%')))
                    sleep(5)
