啟動(dòng)service保存android系統(tǒng)log

作為android開發(fā)工程師，出現(xiàn)了BUG是不是苦于沒有l(wèi)og而苦惱萬分呢，以下敝人提供1套自動(dòng)保存log的方法，供大家鑒戒學(xué)習(xí)：

首先，在產(chǎn)品目錄的init.XXX.rc文件中，添加相應(yīng)的service，

# start log service
 start logd

on property:service.logcat.enable=1
    start logcat_service

on property:service.logcat.enable=0
    stop logcat_service

# log services
service logcat_service /system/bin/logcat -b system -b events -b main -b radio -k -n 10 -v threadtime -r5000 -f /data/Logs/Log.0/logcat.log
    user root
    group log system
    class main
       disabled

service logd /system/bin/sh /system/bin/logd.sh
    user system
    group log
    oneshot

然后，在目標(biāo)平臺(tái)的system/bin下添加腳本文件logd.sh，處理存儲(chǔ)的log日志，和設(shè)置屬性，開啟logcat_service,

#!/system/bin/sh

#
# Global folder & cmd params
#

OUTPUT_DIR=/data
LOG=Logs
index=2

LOG_DIR[0]=$OUTPUT_DIR/$LOG/Log.0
LOG_DIR[1]=$OUTPUT_DIR/$LOG/Log.1
LOG_DIR[2]=$OUTPUT_DIR/$LOG/Log.2

RM=rm
MV="mv"
MKDIR=mkdir
UMASK=umask


# set default permission 0775
$UMASK 002

# Init the three folders

i=0
while [ "$i" -le "$index" ]
do
$MKDIR -p ${LOG_DIR[$i]}
i=$(($i+1))
done

# Transfer the three folders
((i=$index⑴))
$RM -r ${LOG_DIR[$index]}/*
while [ "$i" -ge "0" ]
do
$MV ${LOG_DIR[$i]}/* ${LOG_DIR[$i+1]}
i=$(($i⑴))
done
$RM -r ${LOG_DIR[0]}/*

# start logcat service
setprop service.logcat.enable 1

mkdir /data/www
cp -R /system/var/www/    /data/
ln -s /storage/external/ /data/www/sdcard

諸位，鼓掌吧~~~~
