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(guān)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。
