Android过滤具体应用日志的脚本

Android过滤具体应用日志的脚本

最近新修改完善了一个Android脚本，贴出来和大家分享一下。

功能：按照程序（包名）过滤某一程序的日志，便于更加准确定位问题。

原理：根据报名找到进程ID，然后根据得到的进程ID过滤

代码：

#!/usr/bin/env python
#coding:utf-8
#author:andrewallanwallace@gmail.com
#This script is aimed to grep logs by application(User should input a packageName and then we look up for the process ids then separate logs by process ids).

import os
import sys

packageName=str(sys.argv[1])

command = "adb shell ps | grep %s | awk '{print $2}'"%(packageName)
p = os.popen(command)
##for some applications,there are multiple processes,so we should get all the process id
pid = p.readline().strip()
filters = pid
while(pid != ""):
 pid = p.readline().strip()
 if (pid != ''):
  filters = filters +  "|" + pid

#print 'command = %s;filters=%s'%(command, filters)
if (filters != '') :
 cmd = 'adb logcat | grep --color=always -E "%s" '%(filters)
 os.system(cmd)

假设上述脚本保存成logcatPkg.py 使用方法:

androidyue~/py_works (master)$ logcatPkg.py com.android.phone

结果：

注意：由于是根据pid过滤，所以可能会过滤出一些数字相关的无相关信息。
