python实现过滤单个android程序日志脚本分享

在android软件开发中,增加日志的作用很重要,便于我们了解程序的执行情况和数据。eclipse开发工具会提供了可视化的工具,但是还是感觉终端效率会高一些,于是自己写了一个python的脚本来通过包名来过滤某一程序的日志。

原理

通过包名得到对应的进程id(可能多个),然后使用adb logcat 过滤进程id即可得到对应程序的日志。

源码

代码如下:

#!/usr/bin/env python
#coding:utf-8
#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)

使用方法

代码如下:

python logcatpkg.py com.mx.browser

最新代码

代码如下:

#!/usr/bin/env python
#coding:utf-8
#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)

不足

当脚本执行后,android程序如果关闭或者重新启动,导致进程id变化,无法自动继续输出日志,只能再次执行此脚本。
