Python實現過濾單個Android程式日誌指令碼分享

在Android軟體開發中，增加日誌的作用很重要，便於我們瞭解程式的執行情況和資料。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，於是自己寫了一個python的指令碼來通過包名來過濾某一程式的日誌。

原理

通過包名得到對應的進程ID（可能多個），然後使用adb logcat 過濾進程ID即可得到對應程式的日誌。

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

當指令碼執行後，Android程式如果關閉或者重新啟動，導致進程ID變化，無法自動繼續輸出日誌，只能再次執行此指令碼。
