源码阅读

原来我们主要阅读我们想实现功能是如何实现的（cpu，内存）

我们先从启动类StartUp中run方法看起：

复制代码

for i in range(0,5):
    if self.device.adb.is_connected(self.serialnum):
        is_device_connect = True
        break
    else:
        logger.error("device not found:"+self.serialnum)
        time.sleep(2)

self.serialnum就是配置表中的设备序列号，这一段是用过ADB类中的静态方法is_connected实现的，我们来看一下他们是怎么检查配置中的手机是否链接

复制代码

@staticmethod
def is_connected(device_id):
    '''
                检查设备是否连接上
    '''
    if device_id in ADB.list_device():
        return True
    else:
        return False

复制代码

    @staticmethod
    def list_device():
        '''获取设备列表

        :return: 返回设备列表
        :rtype: list
        '''
        proc = subprocess.Popen("adb devices", stdout=subprocess.PIPE, shell=True)
        result = proc.stdout.read()
        if not isinstance(result, str):
            result = result.decode('utf-8')
        result = result.replace('\r', '').splitlines()
        logger.debug("adb devices:")
        logger.debug(result)
        device_list = []
        for device in result[1:]:
            if len(device) <= 1 or not '\t' in device: continue
            if device.split('\t')[1] == 'device':
                # 只获取连接正常的
                device_list.append(device.split('\t')[0])
        return device_list

通过这一段代码我们可以发现，mobileperf是基于adb命令去读取相应的信息，而他的使用是通过subprocess类中的Popen去操作adb命令，通过adb devices命令判断是否已经链接成功

注：subprocess是python标准库兼容性较好，且是非阻塞性执行，在输入输出的拓展性、错误处理都比较健全完善，后面会在提到这个方法使用。

复制代码

  # 对是否安装被测app的检查 只在最开始检查一次
        if not self.device.adb.is_app_installed(self.packages[0]):
            logger.error("test app not installed:" + self.packages[0])
            return
        try:
            #初始化数据处理的类,将没有消息队列传递过去，以便获取数据，并处理
            # datahandle = DataWorker(self.get_queue_dic())
            # 将queue传进去，与datahandle那个线程交互
            self.add_monitor(CpuMonitor(self.serialnum, self.packages, self.frequency, self.timeout))
            self.add_monitor(MemMonitor(self.serialnum, self.packages, self.frequency, self.timeout))

这里我们节选了一部分代码，当我们知道他基本实现逻辑其实我们大致也可以猜到is_app_installed判断app是否安装他是如何实现的！应该也是通过adb命令去寻找已安装的包是否存在

复制代码

    def is_app_installed(self, package):
        '''
        判断app是否安装
        '''
        if package in self.list_installed_app():
            return True
        else:
            return False

复制代码

    def list_installed_app(self):
        '''
                        获取已安装app列表
        :return: 返回app列表
        :rtype: list
        '''
        result = self.run_shell_cmd('pm list packages')
        result = result.replace('\r', '').splitlines()
        logger.debug(result)
        installed_app_list = []
        for app in result:
            if not 'package' in app: continue
            if app.split(':')[0] == 'package':
                # 只获取连接正常的
                installed_app_list.append(app.split(':')[1])
        logger.debug(installed_app_list)
        return installed_app_list

正如我们所料，他是用过命令adb shell pm list packages 返回的接口进行切割拿到包名，去判断需要测试包名是否在其中

那么他是采集和收集内存/cpu等信息是不是也是这样实现的呢，答案是肯定的

复制代码

        end_time = time.time() + self._timeout
        cpu_title = ["datetime", "device_cpu_rate%", "user%", "system%","idle%"]
        cpu_file = os.path.join(RuntimeData.package_save_path, 'cpuinfo.csv')
        for i in range(0, len(self.packages)):
            cpu_title.extend(["package", "pid", "pid_cpu%"])
        if len(self.packages) > 1:
            cpu_title.append("total_pid_cpu%")
        try:
            with open(cpu_file, 'a+') as df:
                csv.writer(df, lineterminator='\n').writerow(cpu_title)
        except RuntimeError as e:
            logger.error(e)
        while not self._stop_event.is_set() and time.time() < end_time:
            try:
                logger.debug("---------------cpuinfos, into _collect_package_cpu_thread loop thread is : " + str(threading.current_thread().name))
                before = time.time()
                #为了cpu值的准确性，将采集的时间间隔放在top命令中了
                cpu_info = self._top_cpuinfo()
                after = time.time()
                time_consume = after - before
                logger.debug("  ============== time consume for cpu info : "+str(time_consume))

这里我们截取了一段收集cpu的代码，可以发现他是通过一个while循环去调用_top_cpuinfo方法

复制代码

    def _top_cpuinfo(self):
        self._top_pipe = self.device.adb.run_shell_cmd(self.top_cmd, sync=False)
        out = self._top_pipe.stdout.read()
        error = self._top_pipe.stderr.read()

我们接着往下看

复制代码

    def run_shell_cmd(self, cmd, **kwds):
        '''执行 adb shell 命令
        '''
        # 如果失去连接后，adb又正常连接了
        if not self.before_connect and self.after_connect:
            cpu_uptime_file = os.path.join(RuntimeData.package_save_path, "uptime.txt")
            with open(cpu_uptime_file, "a+",encoding = "utf-8") as writer:
                writer.write(TimeUtils.getCurrentTimeUnderline() + " /proc/uptime:" + self.run_adb_cmd("shell cat /proc/uptime") + "\n")
            self.before_connect = True
        ret = self.run_adb_cmd('shell', '%s' % cmd, **kwds)
        # 当 adb 命令传入 sync=False时，ret是Poen对象
        if ret == None:
            logger.error(u'adb cmd failed:%s ' % cmd)
        return ret

不难发现，最终依旧是调用的run_adb_cmd方法去执行的adb命令，最后把收集到数据写入对应文件中，看到这里我们大概可以自己实现一下了

开发自己的安卓性能工具

注：这里工具页面开发我们使用gui开发工具pyside6

前面我们提到了标准库subprocess 这里介绍一下我们会用到的两个方法communicate从子进程的stdout和stderr读取数据。这个方法会阻塞主程序，直到子进程完成，poll检查子进程是否结束，如果子进程正常退出，输出应该为 0；否则为非0值
