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。
