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。
