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：
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
@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
@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。
# 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
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
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
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
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
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
