在Android軟件開發中，增加日志的作用很重要，便于我們了解程序的執行情況和數據。Eclipse開發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

復制代碼代碼如下:

#!/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)

使用方法

復制代碼代碼如下:

python logcatPkg.py com.mx.browser
