在Android軟件開發(fā)中，增加日志的作用很重要，便于我們了解程序的執(zhí)行情況和數(shù)據(jù)。Eclipse開發(fā)工具會提供了可視化的工具，但是還是感覺終端效率會高一些，于是自己寫了一個python的腳本來通過包名來過濾某一程序的日志。

原理

通過包名得到對應的進程ID（可能多個），然后使用adb logcat 過濾進程ID即可得到對應程序的日志。

源碼

代碼如下:

#!/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

代碼如下:

python logcatPkg.py com.mx.browser

最新代碼

代碼如下:

#!/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

當腳本執(zhí)行后，Android程序如果關閉或者重新啟動，導致進程ID變化，無法自動繼續(xù)輸出日志，只能再次執(zhí)行此腳本。
