Python analytics android logs get Activit load time

Recently, there is a need to compare the time of a single activity load of two versions before and after

In the Android log we can see similar Info/activitymanager (2486): Displayed activity com.teleca/. contextmenuactivity:240 MS (total 41289 ms) log, which is the load time of the activity

First get the log through adb logcat > xx.txt, and then analyze the log with the following code:

#-*-coding:utf-8-*-#analyze Android adb logcat log extract activity displayed logImportOSImportRedefAndroiddisplayedlog (ApplicationName, logfile):ifos.path.exists (logfile): with open (logfile) as F:log=f.readlines () activityloadtime= []         forLineinchlog:ifRe.search (R"Displayed%s"%ApplicationName, line): Activitymanagerlog= Line.split (":") Activity= Activitymanagerlog[1].split ("/") [-1] Loadtimestr= Activitymanagerlog[-1].strip (). Strip ('Ms'). Strip ('+')                #An integer that converts the log time to Ms                Try: T=Int (LOADTIMESTR)ifT:loadtime=TexceptValueError:#Filter resident system activity for more than a minute                    Try: Loadtime= Int (Loadtimestr.split ('s') [0]) * + + int (loadtimestr.split ('s') [1])                    exceptValueError:Pass                Printactivity, Loadtime activityloadtime.append (activity, Loadtime)returnActivityloadtimeElse:        Print "log file does not exist"a= Androiddisplayedlog ("com.aaa.bbbb","D:\\log.txt")
