我自己写的时间戳差值，好像有好多问题。。老师能帮忙指出来吗？包含语法和类的用法上面的问题

import os
import time

class LaunchApp(object):
def __init__(self):
self.content = ''
def launch(self):
cmd = 'adb shell am start -W -n com.android.browser/.BrowserActivity'

self.content = os.popen(cmd)
def launchTime(self):
currentTime = time.strftime("%Y-%m-%d %H%M%S",time.localtime())
return currentTime

class StopApp(object):
def __init__(self):
self.content = ''
def stop(self):
cmd = 'adb shell input keyboard 3'
self.content = os.popen(cmd)
def stopTime(self):
currentTime = time.strftime("%Y-%m-%d %H%M%S",time.localtime())
return currentTime

class CalculateTime(object):
def __init__(self):
self.timestamp = 0
def calculate(self):
time = self.timestamp = StopApp.stopTime() - LaunchApp.launchTime()
print time

if __name__ == "__main__":
LaunchApp.launch()
StopApp.stop()
CalculateTime.calculate()

改了几次，好多都是这种报错：

TypeError: unbound method stopTime() must be called with StopApp instance as first argument (got nothing instead)
